Hi!
I’m not 100% sure but I think it is the global warming since increased reenhouse effect leads to a warmer climate and that’s what the global warming is.
Anyways, I hope it helped!
An increased greenhouse effect and the depletion of the ozone layer are examples of global climate change. These are largely driven by human activities, in particular, the emission of greenhouse gases, such as carbon dioxide, which trap heat in our atmosphere, causing global warming. Depletion of the ozone layer, mostly caused by human-made chemicals, reduces Earth's natural protection against harmful ultraviolet rays.
Explanation:The increased greenhouse effect and the depletion of the ozone layer are two examples of global climate change and environmental issues that are primarily driven by human activities. The greenhouse effect refers to the warming of Earth due to the increasing levels of atmospheric carbon dioxide and other greenhouse gases in the atmosphere. These gases absorb and emit radiation, thus trapping heat in Earth's atmosphere, causing global warming.
The depletion of the ozone layer is another important environmental concern. Damage to the ozone layer is mostly caused by human-made chemicals, such as chlorofluorocarbons (CFCs), which reduce the layer. This can reduce the protection we have against the sun's harmful ultraviolet rays.
Both these issues lead to broader impacts on global ecosystems, affecting various species and altering global weather patterns. It's also worth noting that these impacts can be intensified by other environmental issues such as pollution, deforestation, and industrial farming which also contributes to greenhouse gases emissions.

Which statement about natural selection is true?
A.)Natural selection and evolution are two terms for the same phenomenon.
B.)Natural selection is an outdated theory to explain how evolution took place.
C.)Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.
D.)Natural selection is the process by which organisms develop variation in traits, which gives them a better chance of survival.
Answer: C). Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.
Explanation:
Natural selection is a natural phenomena which involves differential survival and reproduction of individuals who have better phenotypic traits over others. Such organisms survive and reproduce in adverse environmental conditions. Thus nature selects the individuals with better traits.
Which of the following scenarios would prevent a population from being in Hardy-Weinberg equilibrium?
A. The population is evolving, and natural selection is favoring one allele over another.
B. The population is stable, but younger generations of the population have a different allele frequency.
C. The population mates at specific times of the year, causing the population to fall out of equilibrium at that time of year.
D. The population will fall out of Hardy-Weinberg equilibrium if natural resources such as food are limited.
The answer is A.
the Hardy–Weinberg equilibrium states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.
hope this helps:)
Answer:
(A) The population is evolving, and natural selection is favoring one allele over another.
Explanation:
According to Hardy-Weinberg equilibrium, the frequency (genetic variation) of population remains stable from one generation to the next generation.
The population will follow Hardy-Weinberg equilibrium if the population size is large, random mating, no natural selection , absence of mutation and gene flow.
If the population is evolving and natural selection favors an allele over another, this scenario will prevent that population to follow Hardy-Weinberg equilibrium.
Thus, the correct answer is option(A).

A)
ATP
B)
CO2
C)
H2O
D)
NADPH
Answer:
the energy needed is carbon dioxide
This energy-carrying molecule is needed to produce glucose. This molecule is ATP. Thus, option A is correct.
What is light-independent (dark) reaction?The light-independent (dark) reaction of photosynthesis is the second chemical reaction of photosynthesis that takes place in the stroma within the chloroplast.
Light-Dependent Reactions of Photosynthesis. The first major set of processes in photosynthesis, in which light energy is initially converted into chemical energy as ATP and NADPH, takes place across the chloroplast thylakoid membranes, between the chloroplast stroma and the thylakoid space.
These electrons move through structures in chloroplasts and by chemiosmosis, make ATP. The hydrogen is converted to NADPH which is then used in the light-independent reactions. Oxygen diffuses out of the plant as a waste product of photosynthesis. This all happens in the grana thylakoid of chloroplasts.
Therefore, This reaction uses the products of light dependent reactions which are the energy carrying molecule (ATP) and NADPH (which provides electron) to convert carbon dioxide and other compounds into glucose.

Explain how scientists use geologic time to determine the age of landforms.
Answer: every time there is more information it causes the scientist to look for more information
Hope it helped!
Answer:
As explained below.
Explanation:
The age of the earth is derived from studying the geologic time scale of the earth by the carbon dating and analysis of the fossils. Rocks on the earth are sufficient enough to show the age of landforms. The first attempt to make the geologic time scale was done in 18 C.E thus the earth was divided into the Primary, Secondary, Tertiary, and Quaternary landforms. It was William Smith who gave the successive period framework and suggested virtually finite earth. The primary period divided into Precambrian eon which included Hadean, Archean, Proterozoic periods. Which later on developed as Cambrian, Ordovician, Silurian, and Devonian, Carboniferous and Permian periods and the development of the secondary landforms the splitting of super landmasses and the formation of the tertiary period as the Triassic, Jurassic and the Cretaceous periods. The quaternary period stated with the Miocene, Pliocene, Pleistocene and continued to the present Holocene. From 4600-635 million years, and then tp peent 0.0042 million years.9.

What are two ways that harvesting algae from the ocean may benefit human society? How might the harvest of algae negatively impact the ocean communities where the algae grows? How could this be prevented?
Answer: Hope I help!!!!!b:D
Explanation: Well, things eat the algae, and if algae is taken from an ecosystem, then it could unravel. Another thing, depending on the species, algae helps break things down like waste and clean the water!
Answer:
The harvest of algae allows them to be used for food and medicine production, as they are a source of proteins, vitamins and minerals. In addition, this harvest reduces the risks of the process called "red tide", which occurs when the algae population becomes so large in the aquatic environment, that it ends up throwing toxic elements on it, which negatively affects marine life.
The downside of harvesting algae is that harvesting can be done in a way that drastically reduces the population of algae in the aquatic environment and harms animals that have algae as their main food source. In addition, algae are responsible for much of the oxygen in the atmosphere, when harvesting it aggressively, it can impair the concentration of oxygen in the atmosphere. To avoid these problems, it is necessary to harvest the algae in a conscious and sustainable way.
Explanation:
Algae can be described as eukaryotic, autotrophic organisms that can be unicellular or multicellular, present in most rivers and oceans. Despite being very similar to plants, algae are not considered plants, but a totally different and intriguing organism. The algae make photosynthesis and are largely responsible for the oxygen available for our breathing.
Describe the function of a membrane proteins
Answer: Membrane proteins perform a variety of functions vital to the survival of organisms: Membrane receptor proteins relay signals between the cell's internal and external environments. Transport proteins move molecules and ions across the membrane. ... Cell adhesion molecules allow cells to identify each other and interact.
Cell membrane proteins, which include integral and peripheral proteins, play a crucial role in regulating substance movement into, out of, and within a cell. They serve as channels for substance transport, act as enzymes, or help differentiate cells from each other.
Explanation:The function of membrane proteins in a cell is to regulate the movement of substances. These proteins are often embedded in the cell membrane and regulate the concentration of substances like ions, nutrients, and waste products inside the cell. There are primarily two types of proteins associated with the cell membrane: the integral proteins and the peripheral proteins.
Integral proteins are embedded in the membrane and serve as channels or pumps to move materials into or out of the cell. A common example of an integral protein would be a channel protein that selectively allows specific materials to pass into or out of the cell.
On the other hand, peripheral proteins are typically located on the inner or outer surface of the lipid bilayer. They can also be attached to the internal or external surface of an integral protein. These proteins perform a specific function for the cell. For instance, peripheral proteins on the surface of intestinal cells act as digestive enzymes to break down nutrients into sizes that are small enough to pass through the cells and into the bloodstream.

What happens when the fur of a otter is soiled or clumped
Because they rely on their dense fur for insulation from the chilly ocean water, sea otters are particularly vulnerable to the detrimental effects of an oil spill. If a sea otter swims into an oil spill, its fur becomes soiled and loses its insulating qualities, allowing water to penetrate to its skin, causing hypothermia and ultimately, death.
hope this helps?
Soiled or clumped fur in an otter can compromise its insulation by losing trapped air bubbles, increasing the risk of reaching thermal equilibrium with cold water and leading to potential hypothermia.
When the fur of an otter is soiled or clumped, it can lose its insulating properties. The otter's fur is special because it traps air bubbles, which provide insulation against the cold water. If the fur becomes clumped or soiled, these air bubbles can be lost, making the fur less effective at insulating the otter. Without the trapped air, the otter could reach thermal equilibrium with the cold water more quickly, which is dangerous as it could lead to hypothermia and be life-threatening for the animal. Furthermore, otters have hydrophobic lipids in their fur that help to protect them from the elements by repelling water and keeping their fur from getting waterlogged.
