Population growth is regulated by density-dependent and density-independent factors. Understanding these factors is important for managing populations and preventing extinction or overpopulation.
Explanation:Nature regulates population growth in a variety of ways. These are grouped into density-dependent factors, in which the density of the population at a given time affects growth rate and mortality, and density-independent factors, which influence mortality in a population regardless of population density. Conservation biologists want to understand both types because this helps them manage populations and prevent extinction or overpopulation.

How does the average distance between galaxies now compare with the average distance between galaxies at the time the supernova exploded?
Answer: dnow/dpast =
2.9
Explanation:
Stretching of the Universe results in white dwarf supernova, an observed distant had a cosmological red shift of z = 1.6, the cosmological red shift value indicates the Hubble/recession velocity or distance of the object.
Answer:
The formula for these kind of problems is:
Z = ((distance now)/ (distance before)) - 1
We know, Z=1.6
So, we get:
(Distance now)/ (distance before) = 1.6 + 1 = 2.6
Explanation:
The massive cosmic explosions due to burning of stars instead of fading ends their evolution is known as supernovae. The supernovae explosion leads to dropping of matter into space at nearly nine thousand to twenty five thousand miles that is 15,000 to 40,000 km/s. These unconditional blasts produce most of the materials in the universe which includes some elements, such as iron, which helps to make up our needs and even our planets'. The Supernovae is solely responsible for produced heavy elements, so we carry the remains of these distant explosions within our own bodies.

Why does magma in the mantle rise to the crust above it?
The magma rises to the crust above it mostly because of the cracks that appear in the crust and the high pressure from the mantle that pushes the magma through these cracks. The cracks in the crust appear because of the tectonic activities, on and in close proximity to the plate boundaries. This is why the volcanic activities, a product of rising magma, are found along the plate boundaries. The magma can rich the crust and solidify in it, or it can come out on the surface in the form of lava flows. The one that solidifies inside the crust forms the intrusive igneous rocks, while the one that comes on the surface forms the extrusive igneous rocks. The rocks formed from the magma are the basis for the formation of the other rock types, as well as for the formation of land masses, and soils.

In the 1920s, a split developed between Nationalists who favored Western democratic ideals and Nationalists who wanted to share land and power with all Chinese people.
Answer:
wanted to share the land and the power with all the Chinese people.
Explanation:
Nationalists fought for the local warlords along with their armies and, they felt like they need to have full power. Some members adopted a communist policy and others adopted the marxism principles. As the communist gained grounds and established the PRC they are they are claimed a legitimate government of China.Scientists discovered that the Eocene time period existed in Earth’s history around 34 MYA.
What do they need to do to determine what time period Eocene belongs to on the geologic time scale?
learn what happened during Precambrian time
study information related to the Cenozoic era
view the timing of events in the Mesozoic era
research events that happened during the Paleozoic era
Answer:
study information related to the Cenozoic era
Explanation:
A good understanding of the geologic time scale is required here.
The absolute age of 34mya for the Eocene falls in the Cenozoic era.
The geologic time scale is divide into Eons, Eras, Periods, Epoch, Age.
The Eons are larger divisions than any other group.
The GTS is divided into 4 era:
Precambrian
Paleozoic
Mesozoic
Cenozoic
The Precambrian era is the oldest while the Cenozoic is just a few million years.
The age of the Cenozoic lies between Recent to 66mya ago. This is where the Eocene should lie.
Study information is the correct option.
What type of rock is continental crust generally made of
Answer:
Granite
Explanation:
The continental crust is the upper most layer of the Earth, being higher than the oceanic crust, and floating on top of the denser mantle layer bellow it. It is 35 km thick on average, but it is not very dense. The continental crust is mostly made out of granitic rocks. These rocks have been made out of mostly by basaltic magma/lava in the past. The majority of this magma/lava that has cooled and created the crust has remained in the form of igneous rocks, while some have experienced metamorphism, and some have become sedimentary rocks. The granite though is not the densest and heaviest of rocks, making this crust the lightest of all. The continental crust currently occupies around 40% of the top layer of the Earth, but that is something that has been constantly changing, with certain periods have only 10%,and others 60%.
What a deep valley that forms where an oceanic plate collides with a continental plate is called?
Answer:
Oceanic trench
Explanation:
On the places where there's convergent plate boundary between an oceanic and continental plate, there's a subduction zone. The oceanic plate is denser, heavier, lower than the continental plate. Because of that, the oceanic plate is moving below the continental plate, slowly getting into the mantle where it is melted and destroyed. On the boundary itself, a gap opens up between the plates, a gap that is under constant pressure and geological activity. This gap is basically a valley at the bottom of the ocean, being much deeper than the surrounding area. The term used for these places is an ocean trench, and there's lot of them around the world where there's a convergent plate boundary between an oceanic and continental plate. The best known of these ocean trenches, also being the deepest place on Earth, is the Mariana trench, located on the boundary between the Filipino and the Pacific plates.
Final answer:
A deep valley formed where an oceanic plate collides with a continental plate is called an oceanic trench. Examples include the Mariana Trench and the Cascadia Subduction Zone, which are known for geological activities like earthquakes and the formation of magma.
Explanation:
A deep valley that forms where an oceanic plate collides with a continental plate is known as an oceanic trench. When the denser oceanic plate subducts beneath the less dense continental plate, it plunges into the mantle, creating a subduction zone marked by a trench. This geological feature is among the deepest parts of the ocean floor, where immense pressures and dark environments exist. The Mariana Trench is a quintessential example of such a formation resulting from this type of plate tectonic activity.
Trenches are significant because they are sites of intense geological activity, including frequent earthquakes and sometimes volcanic activity due to the subduction of the oceanic crust and the resulting formation of magma. This process can also lead to the creation of volcanic mountain ranges or islands adjacent to the continental margin. The Cascadia Subduction Zone, extending from the northwest coast of the United States to the Pacific Coast of Canada, is an active subduction zone that forms part of the Ring of Fire known for its seismic and volcanic activities.
How does oceanic crust move along mid-ocean ridges?
away from dense crust
parallel to the ridge
away from the ridge
under less dense crust
Answer:
away from the ridge
Explanation:
The mid-ocean ridge is formed on the divergent plate boundary. Here the magma from the mantle manages to penetrate to the surface, and as it does, cools off quickly, and creates new crust. With the constant creation of new crust, the old crust is pushed away from the newly created one. The old crust gradually is pushed further and further away from the ocean ridge, while new crust is constantly pilling up at the mid-ocean ridge. Eventually this will lead to the old crust being pushed to a convergent plate boundary where it will be subducted and melted.
Answer:
Oceanic crust is formed in the mid-ocean ridges by volcanic activity. The Mid-ocean ridges are mountain ranges formed by plate tectonics situated under the water, when the tectonic plates move, the ocean crust move away from the ridges. Lithosphere is formed by the crust and the solid mantle layer.

Which independent country shares an island with one of the regions of the united kingdom?
Answer:
The answer is wales.
Explanation:
Hope that helps:)
✌
The Republic of Ireland shares the island of Ireland with Northern Ireland, making it the independent country that shares an island with a region of the United Kingdom.
The independent country that shares an island with one of the regions of the United Kingdom is the Republic of Ireland. The Republic of Ireland shares the island of Ireland with Northern Ireland, which is one of the four constituent regions of the UK, the others being England, Scotland, and Wales. Ireland became an independent nation in 1921, following the Irish War of Independence, while Northern Ireland opted to remain part of the United Kingdom.
Scotland, while also having strong independence movements, is not the correct answer because it does not share an island with an independent country; it is part of the island of Great Britain.
Devolution has allowed Scotland, Wales, and Northern Ireland certain degrees of self-governance, but only the Republic of Ireland is a completely independent state sharing an island with a UK region.

During the Carboniferous Period, what were largely responsible for regulating the climate on land masses? Please explain.
A. Large oceans
B. The glaciers
C. Land masses
D. The North and South Poles
Answer:
A. Large oceans
Explanation:
The Carboniferous period, the majority of the time, was a very warm period. The sea levels were high, the continental masses smaller than today, and they were still not connected to one another. This led to a situation where there were multiple large seas surrounding the smaller, flatter, land masses, and one very large ocean. Because of the high sea levels and the positions and size of the continents, the oceans were able to easily dictate the climate throughout the land masses, resulting in a warm and wet period, where the flora and fauna flourished. At the end of this period the climate suddenly changed, and the main cause was the merging of the continents and the formation of Pangaea.
Answer:
Large Oceans

Based on what we know about our own solar system, the discovery of hot Jupiters came as a surprise to scientists because these planets are __________.
Based on what we know about our solar system, the discovery of hot Jupiter came as a surprise to scientists because these planets are extremely close to their host stars, orbiting with periods of just a few days. The option (A) is correct.
The extreme heat and proximity to their stars challenge conventional notions of habitability and planetary dynamics. The study of hot Jupiters has prompted revisions to theories of planetary migration, suggesting that these planets may have formed farther out in their systems before migrating inward.
Understanding their formation and evolution sheds light on the diverse range of planetary systems beyond our own. This contradicted existing models of planetary formation, as these gas giants were thought to form farther from their stars.
This question is not complete, Here I am attaching the complete question:
Based on what we know about our solar system, the discovery of hot Jupiters came as a surprise to scientists because these planets are __________.
A) Extremely close to their host stars, orbiting with periods of just a few days.
B) Composed primarily of rocky material, unlike our gas giant Jupiter.
C) Exhibiting retrograde motion, contrary to the standard direction of planetary orbits.
D) Characterized by thick atmospheres composed mostly of hydrogen and helium.
How is revolution of the earth responsible for change in season?
Answer:
These revolutions of the Earth, refer specifically to its translation movement, which consists of the elliptical orbit that describes the Earth around the Sun.
So, a complete revolution around the Sun occurs every 365 days, 5 hours, 48 minutes and about 46 seconds. It is thanks to this movement and that the Earth's axis is tilted with respect to the plane of its orbit about [tex]23\º[/tex], that the four seasons of the year exist.
That is why some regions receive different amounts of sunlight according to the seasons of the year. These variations are more evident near the poles and softer or imperceptible in the tropics (near the equator). This explains the fact that while in the northern hemisphere it is summer and there are high temperatures (because the Sunlight incides more perpendicularly in this area during this season), in the southern hemisphere it is winter and very low temperatures are recorded, and vice versa.
However, as the Earth continues its translational movement, the solar radiation affects more obliquely, as is the case of the spring and summer seasons.
It should be noted that near the equator, as previously mentioned, these changes are not very noticeable and the temperature tends to be more stable, with only two seasons: rain and drought.

Which of the following represent the largest volume of freshwater found on Earth?A. Ice sheets and glaciersB. Water vapor in the atmosphereC. RiversD. LakesE. Groundwater
Answer:
A. Ice sheets and glaciers
Explanation:
The majority of the freshwater on Earth is not actually in liquid form, but it is frozen. Around 87% of the total freshwater reserves are located in the ice sheets around the North Pole and South Pole, as well as the glaciers in close proximity tot he poles and the higher mountains. This is a big problem since only 13% of the freshwater reserves are in liquid form, 12% of which are groundwater, and only 1% being a surface water. Big portion of the surface water has been polluted, thus it is not good for usage, while the groundwater is constantly being depleted.
The freshwater reserves vary from period to period, and it depends a lot on the climate. In the periods when there's an ice age, the ice sheets and glaciers account for even higher percentage of the freshwater reserves, but in the warmer periods, the surface water and the groundwater increase.

Every nation has its own state.
True or False
Answer: im pretty sure thats false
The statement that every nation has its own state is false. While there are about 195 recognized states, there are around 5,000 nations characterized by shared language and history, and many states contain multiple nations.
The statement 'Every nation has its own state' is false. There are approximately 195 states in the world, each with its own characteristics such as territorial borders, government, and sovereignty. However, there are about 5,000 nations, which are populations with common language, history, and cultural traits. Many states are multinational entities, and very few are nation-states, where the nation wholly comprises the state. For example, Japan is often seen as a nation-state with a majority of the population being ethnically Japanese, but it also includes minority groups like the Ainu.
Nation-states are ideals where citizens share a common heritage and governance, such as Italy for Italians, or Germany for Germans. Yet, this ideal is rarely achieved due to internal diversity and the presence of various ethnic groups within the borders of a state. The concept of a nation-state is more pronounced in Europe but remains a challenge due to cultural diversity.

In what formation are Mariana trench plates involved?
Answer:
Subductio zone
Explanation:
The Mariana trench is a result of the convergent plate boundary between the Filipino plate and Pacific plate, creating a subduction zone. The Filipino plate is not a large one, but still the much larger Pacific plate is subducting below it. The reason for this is that the Pacific plate is denser, heavier, lower. At the boundary itself, the Pacific plate moves below the Filipino plate, slowly getting into the mantle layer and getting melted and destroyed. The subduction zone though makes a large gap between the two plates, a gap that is constantly under immense pressure and experiences constant geological activity. This gap is filled with the ocean water, and it is actually the deepest place on the surface of the Earth with over 11 km bellow sea level. The name of it comes from the island chain next to the subduction zone, the Mariana Islands, thus it is called Mariana trench.
Which statement describes summer in the Northern Hemisphere?
Answer:
A. The North Pole is tilted towards the sun

In Northern Hemisphere's summer, the North Pole is tilted towards the sun.
That's why the days are longer and warmer. While it's summer in the North, it's winter in the South.
The other offered answers are wrong:
B. South Pole is tilted towards the sun. That's when it's winter in the Northern Hemisphere.
C. the sun's rays grow less direct. No, on the contrary, that's why we get warmth in summer.
D. The sun appears directly overhead. That's not possible at any time of the year in the Northern hemisphere, you have to be close to the Equator line for this to happen.
The collapse of the iron core in a massive star results in a
A star exists due to the balance between two forces:
1. The gravity force that tries to squeeze the stellar material into the smallest and most compact ball possible.
2. The nuclear force, generating heat and pressure in the center of the star that tries to push all the material out.
Now, when the star has occupied all its nuclear fuel, the expansive pressure can no longer counteract gravity and the star suddenly collapses.
When this happens, a supernova is formed, which causes the expulsion of the outer layers of the star by means of powerful shock waves, enriching the space that surrounds it with heavy elements.
So, it can be said that a supernova is the bright, last breath of a star that is at least five times more massive than the Sun.
Name the layer of the atmosphere where jets fly through and contains ozone layer
Answer:
Stratosphere
Explanation:
The layer through which the jets are flying is the stratosphere. This atmospheric layer is the second layer by distance from the lithosphere, being above the troposphere, and bellow the mesosphere. It is a layer where the gasses are much more dispersed than in the troposphere, thus making it less dense. On the other hand, it has air movements that are are relatively strong and constant, which is something that is very useful for flight, thus the jets are flying in this layer in order to have easier and cheaper flight. What makes this layer very important and marking is the layer in itself, the ozone layer. This layer is crucial for the survival of the living organisms on the planet, as this is the layer that stops and absorbs the majority of the UV rays from the sun, thus not allowing them to reach the surface at their full potential, stopping them to fry alive the living organisms.
Which artificial waterway connects the pacific ocean to the atlantic ocean?
Answer:
The Panama canal
Explanation:
Opened in 1914, the Panama canal allows maritime traffic to travel between the Pacific and Atlantic oceans very rapidly through a system of locks (2 on the Pacific side, one in the Atlantic side), and the boats pass through an artificial lake crossing the whole country of Panama.
It takes just a few hours to cross from one side to the other, while it would take weeks to go down to the tip of South America and back up.
In 2016, the canal opened new locks, that can receive larger boats.
What two kinds of fog are the result of adding moisture to a layer of air?A) radiation and upslope
B) advection and radiation
C) steam and frontal
D) upslope and steam
Answer:
B
Explanation:
Development of fog by radiation occurs mainly over land when the land loses heat by radiation. The land hence cools the atmosphere above. The moisture in this air then reaches dewpoint and fog forms.
Development of fog by advection can occur over both land and water. It involves warm moist air mass moving over a cool/cold land or water and hence the warm moist air cools and the moisture in it reaches dew point forming fog.
