Answer:
C: nitrogen that cannot be used by organisms
Explanation:
Free nitrogen is simply molecular nitrogen (N2). Nitrogen, in its molecular form, consists of two nitrogen atoms bound together with a tripple bond. ... So basically, any nitrogen that is in an organic compound is considered “fixed” nitrogen and N2 is considered to be “free” nitrogen.

Wild salmon spend most of their lives in the ocean but return to freshwater rivers to spawn, or reproduce. Most wild salmon will only spawn in specific spawning grounds in the rivers in which they were born. The construction of hydroelectric dams in rivers has blocked the paths of some salmon returning to their spawning grounds. This has led to population declines. Which method would be most effective in preventing further wild salmon population declines caused by the construction of hydroelectric dams?
Answer:
The creation of natural sanctuaries may be a useful approach to combat the extinction of this species
Explanation:
Natural sanctuaries are areas protected by the Government. These delimited areas preserve the habitat of native species with the aim they can reproduce and thus avoid their extinction.
Answer and Explanation:
Answer: A
Constructing passage ways near the dams to allow to salmon to swim around blocked rivers.
The development of dams in streams has hindered the way of certain salmons getting back to bringing forth grounds. The most ideal approach to defeat this is to make the entry ways close to the dams to permit salmons to swim in regions which have impeded because of dams. So salmons can got back to the producing ground and can generate which prompts increment in their populace.

The data shows that recently the shark population has increased. How will the increase in the shark population affect the other populations? Be sure to explain whether the sea otter population, the sea star population, and the clam population will change, and why
Answer:
There is no data to show but there would definitely be a decrease in the population of the other organisms in lower trophic level (sea otter).
Explanation:
This question involves an aquatic food chain involving organisms like clams, sea stars, sea otters, and sharks. In this question, the shark appears to occupy the highest trophic level i.e. tertiary consumer. Ideally, as the food chain progresses from the lowest to highest trophic level, the population of each organism decreases.
However, an increase in the population of sharks will mean more mouths to feed on other consumers. Hence, causing a decrease in the population of other organisms in lower trophic level especially the organism that occupies the secondary consumer trophic level.
An increase in the shark population can decrease the populations of their prey, like sea otters and sea stars, possibly leading to an increase in their prey, such as clams. However, the impact is complex and depends on the specifics of the ecosystem, including factors like overfishing and environmental changes.
Explanation:The recent increase in the shark population is likely to have a cascading effect on other marine populations. As apex predators, sharks control the populations of other marine species through predation which maintains the health and balance of the ecosystem. With more sharks, the populations of their prey, like sea otters and sea stars, may decrease due to increased predation. This, in turn, could lead to an increase in the populations of sea otters' and sea stars' own prey, such as clams, if sea otters and sea stars are less numerous to hunt them.
However, the overall impact on the sea otter population, sea star population, and clam population depends on the complexity of the ecosystem and the specific feeding relationships. For instance, if sea otters are heavily preyed upon by sharks, their decreased numbers could lead to an unchecked growth in sea urchin populations, which sea otters usually keep in balance. Sea urchins feed on kelp and could decimate kelp forests, negatively impacting many species dependent on this habitat. Conversely, a reduced sea star population could allow for the bivalve populations, including clams, to increase, potentially leading to overgrazing on their food resources.
It's important to note that the dynamics of marine ecosystems are highly complex and influenced by multiple factors including human activities such as overfishing and environmental changes. For example, commercial fishing activities disproportionately targeting large predatory fish such as sharks effect a process known as 'fishing down the marine food web' which can destabilize marine ecosystems. Therefore, changes in shark populations should be monitored and managed carefully to ensure the health of the overall marine ecosystem.
How does a coronal mass ejection (CME) affect the solar wind?
A CME adds more particles to the solar wind, intensifying it.
A CME does not affect the solar wind but it does affect auroras.
A CME blocks the solar wind, causing it to fade.
A CME increases the amount of energy in the solar wind.
Answer:
Option A
Explanation:
Corona is defined by the strong magnetic fields. When these strong magnetic fields confine solar atmosphere and produces violent bubble of gases then it is said to cause coronal mass ejection (CME).
When a CME passes through the solar wind, it causes production of high velocity solar energetic particles that follow magnetic field lines and passes through the space between the Sun and the Earth. The charged particle added by CME intensifies the solar wind.
Hence, option A is correct
Final answer:
A CME adds more particles to the solar wind, intensifying it and causing various effects on Earth such as heating the ionosphere, increasing atmospheric drag on satellites, and the potential for solar storm damage.
Explanation:
A coronal mass ejection (CME) affects the solar wind by adding more particles to it, thus intensifying the solar wind. These ejections send tens of millions of tons of coronal material, primarily protons and electrons, into interplanetary space at high speeds of 500-1000 kilometers per second. This increased density and energy can have various effects on Earth, including heating the ionosphere, expanding it, and causing disturbances to satellites and communications systems due to increased atmospheric drag. Furthermore, when a CME reaches Earth, it can distort Earth's magnetic field, potentially leading to solar storm damage by inducing electrical currents and accelerating electrons to high speeds, which can adversely affect satellite operations.

Here is my biology test, (I'm not even sure if this is biology) I'll only post pictures and I'll do a second post once I get more points. I also bunched up a bunch of them to save time and picture space.
Answer and Explanation:
1) In the position "P" the sun´s solar altitude would be the highest in Rockville, Maryland. At this point, it is summer in the northern hemisphere, and the sun is heating directly to the cancer tropic. Maryland is near this tropic, so position"P" could be considered the season in which the sun would be highest in relation to this point.
2) The earth at position V is experiencing winter in the northern hemisphere because the angle of sunlight is more indirect in this hemisphere. It is summer in the hemisphere that is inclined towards the sun and winter in the other hemisphere which is inclined far from the Sun. The hemisphere that is inclined towards the Sun is hotter because sunlight travels more directly to the Earth's surface and less light is scattered through the atmosphere. This means that whenever it is summer in the southern hemisphere, it is winter in the northern hemisphere. The hemisphere that is inclined towards the Sun has longer days and shorter nights. That is why during the summer the days are longer than during the winter.
3) In position V the sun´s path through the sky would be the highest in Australia. At this point, it is summer in the southern hemisphere, which means that the sun is heating the earth directly in the Capricorn tropic. This tropic passes straight through Australia, so this is the position in which the sun would be the highest in this country.
4) In positions U and D the earth experiences 12 hours of daylight and 12 hours of darkness. At these two points, the sun´s rays reach the equator at approximately the same angle every day. This is why there are no seasons at this latitude. Every single day of the year the equator receives about 12 hours of sunlight and 12 hours of darkness.

how is fresh water collected in the rain forest?
Answer:
if you mean how you can gain water in the rainforest?
Kindly, look at below ^_^
Explanation:
The role of rainforests in the water cycle is to add water to the atmosphere through the process of transpiration (in which plants release water from their leaves during photosynthesis). This moisture contributes to the formation of rain clouds, which release the water back onto the rainforest.
Water Basics
The first thing you should do if you're stranded in the wild is find a source of drinkable water. The most obvious sources are streams, rivers and lakes. Animals always know where the water is, so be on the lookout for wildlife or animal tracks. Lush green vegetation is also a sign that water is nearby. Swarming insects may be a hassle, but they also signal that a water source isn't far away. Bird flight paths in the morning or evening can point you in the right direction. Stay on the move until you find a water source. When you pause to rest, use your ears -- rivers can be heard in the quiet woods from great distances. Remember that water always flows downhill, so low-lying areas and valleys are a good bet.
If you find a muddy area, there may be groundwater available. Dig a hole about a foot deep and one foot in diameter and wait. You may be surprised to find that the hole is soon filled with water. This groundwater will be muddy, but straining it through some cloth will clean it up, and it will get you by in the short term. It's crucial to remember that any time you drink found water without purifying it, you're taking a risk.

Which of the following is not true statement: When the egg hatches, the baby salmon can find its own food right away. The baby salmon knows where to go after hatching. The baby salmon needs the adult salmon to teach it how to navigate. The baby salmon can protect itself from predators.
Answer:
This is a behavior called natal homing. In the behavior, the animal uses geomagnetic cues from the earth as a way of finding its way back to the location it was born as a way of spawning or breeding in the same location.
Explanation:
Hope it works!^^
Final answer:
The incorrect statement about baby salmon is that they need adult salmon to teach them how to navigate. Baby salmon are born with the instincts they need for survival and navigation, and they embark on their journey alone, using their innate behaviors and keen sense of smell.
Explanation:
The statement that is not true about baby salmon is: The baby salmon needs the adult salmon to teach it how to navigate. When salmon hatch from their eggs, they already possess the instincts necessary to find food and begin their journey downstream towards the sea. Unlike ground-nesting birds, baby salmon, newly hatched as larvae with a yolk sac, do not require their parents to teach them how to survive. Rather, they rely on innate behaviors. As juveniles, they embark on a perilous trek downriver to the ocean, facing predators such as bears and eagles along the way. After spending years in the ocean growing and feeding on an abundant diet, mature salmon return to spawn at their birthplace, guided by their remarkable homing instincts, which scientists believe may be linked to their keen sense of smell.

Juanita and Juan visit a marriage counselor because they are contemplating divorce. Although the couple started out blissfully in love, they are not getting along well, especially since their children reached their teens. Based ONLY on the U-shaped curve ofmarital satisfaction, what should the therapist advise?
A)"Hold off on divorcing. You are apt to reconnect with each other at the empty nest."
B)"If you are not happy now, you'll feel worse after the children leave."
C)"Expect to feel exactly the same way about each other after the children leave."
D)"There is no research that addresses this issue."
Answer: The correct answer to the question is option A
HOLD OFF ON DIVORCING.YOU ARE APT TO RECONNECT WITH EACH OTHER AT THE EMPTY NEST.
Explanation: The U-shaped curve of marital satisfaction simply explains that there is always maximum happiness and marital satisfaction in the beginning of marriage or any relationship, however,this happiness and fulfilment isn't long-lived,the happiness declines with age due to overwhelming parental duties and obligation.but the good this out of it is that the declining marital happiness and fulfillment will definitely rise again if the relationship or marriage stand the rest of time through mutual understanding and appropriate/adequate communication and love.
So in a nutshell,we can say that marriages are happiest during the period of honeymoon that is few months following weddings if there is, then this happiness declines but further rises at the empty next.

Answer:
See explaination
Explanation:
The independent variable used in study are - different concentrations of drug used for treatment.
We basically made use of two groups in the experiment, control and treatment.
In control group cells are only incubated in media without drug.
While in treatment group cells are treated with different concentrations of drugs.
These two groups provide the idea that actually effect of drug on cell proliferation. Control group growth will be taken as 100% . And cell growth in presence of drug will be compared with control group to see he effect of drug on cell proliferation.
Both drugs have different toxicity on cells. Gossypol is highly toxic than Fx11. So lower concentration drug has been used for gossypol and a higher range is used for Fx11 in the experiment.
The independent variable is the concentration of the substances FX11 and gossypol. Control cells aren't exposed to these substances while experimental cells are. Researchers may use a different range of concentrations to study dose-dependent responses or due to different potencies of the substances.
Explanation:Given the nature of your question, the experiment seems to involve the usage of a substance referred to as FX11 and another one called gossypol, being tested in different concentrations on cells. The independent variable in this experiment is likely to be the concentration of FX11 and gossypol, as this is what is being manipulated or changed to monitor effects on the cells.
The difference between control cells and experimental cells lies in how they are treated during the experiment. Control cells would not be exposed to FX11 and gossypol, serving as a baseline to compare the results from the experimental cells that have been exposed to these substances. Therefore, any changes seen in the experimental cells can be attributed to the effect of the substances administered.
As for why the researchers used a different range of concentrations for FX11 than gossypol, it might be because they have different potencies or expected effects, or it could be a way to examine dose-dependent responses across a broader range.

After photosynthesis is finished inside of a plant, six molecules of oxygen have been produced, as well as a single molecule of C6H12O6, otherwise known as
In photosynthesis, a plant uses sunlight, carbon dioxide, and water to produce glucose and oxygen. This two-part process, encompassing light-dependent and light-independent reactions, converts low-energy molecules into high-energy ones.
Explanation:After photosynthesis occurs inside a plant, six molecules of oxygen and one molecule of glucose (C6H12O6) are produced. This occurs through a multi-step process that utilizes energy from sunlight, carbon dioxide, and water (6CO₂ + 6H₂O) to create glucose and release oxygen (C6H12O6 + 6O₂). Essentially, the plant uses light energy to convert low-energy molecules (carbon dioxide and water) into high-energy molecules (glucose and oxygen), which are crucial for life.
This is depicted in the overall equation for photosynthesis. However, it is important to note that while the equation looks simple, in reality, photosynthesis consists of two parts: the light-dependent reactions and the light-independent reactions or Calvin cycle. These stages involve various intermediate reactants and products, making the process much more complex than it initially appears.

A population of arctic hares burrows into the snow for shelter. It is found
that the hares on the smaller side are able to burrow between rocks, as
well, providing extra protection from predators. Over time, the hare
population becomes smaller in size, shifting the normal distribution curve for
hare size.
What type of selection is this?
Answer:
well, providing extra protection from predators. Over time, the hare
Explanation:
Artic hares are commonly found in northern Canada and coasts of Greenland. Some are found in artic Europe and Asia. They are found on sea icing and are herbivore dependent on land plants for food. 20% mass part of their body is fat insulation and they are low climate animal. They dig into the ground or burrow under the snow during cold weather. It's a way to offer protection against the harsh weather and protection against predators. This is a form of behavioral selection.
Final answer:
Arctic hares that are smaller in size are favored by environmental pressures because they can hide in snow burrows and rock crevices, leading to directional selection which shifts the population's size distribution curve towards smaller sizes.
Explanation:
The situation described with the population of arctic hares demonstrates a phenomenon known as directional selection. This type of selection occurs when environmental pressures favor one extreme of a trait distribution, in this case, smaller size in hares. As smaller hares can burrow into the snow and also fit in crevices among rocks for protection from predators, they are more likely to survive and reproduce, passing on their genes for smaller body size. Over time, this selective pressure results in the overall population becoming smaller, shifting the normal distribution curve for hare size towards the smaller end.
