W Within a forest ecosystem, there is a large amount of diversity among members of a warbler species. Of the following stages of meiosis illustrated for a typical cell, which contributes most to diversity among the warblers? Pay special attention to the chromatids.
Answer:
Explanation:
How a Forest Ecosystem Matures . Forest ecosystems tend to always be moving toward maturity or into what foresters call a climax forest. This maturing, also called forest succession, of the ecosystem increases diversity up to the point of old age where the system slowly collapses. One forestry example of this is the growth of trees and the entire system moving toward an old growth forest.
A Large amount of warbler species, crossing over between homologous chromosomes, is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.
There are different mechanisms involved in producing genetic variation among descendants, are-
Crossing-over between homologous chromosomes (prophase 1), The Random lining of homologous chromosomes (metaphase 1), Random fertilization
The Crossing-over events occur between two homologous chromosomes within the equatorial plane and make the daughter cells genetically different from the first one.
The Chiasma is the position where two homologous chromatids interchange genetic information, giving an area for brand spanking new genetic material or information to be provided to descendants.
After crossover, homologous chromosomes get separated again. In the attached image there are four different stages of meiosis.
Stage C is the one that contributes foremost to diversity. We can see that crossover has already occurred between homologous chromosomes and that they have already interchanged segments.
In the image, you will see the difference between chromosomes that have gone through the crossing over mechanism, and chromosomes that have not. The difference in color represents segments interchange and variation.
Therefore, that answer shows the contribution to diversity among the warblers.

systematic desensitization.
aversive conditioning.
Explanation:
it is systematic desensitization.
Creating a list of anxiety-triggering situations and training in relaxation are important aspects of SYSTEMATIC DESENSITIZATION.
Systematic desensitization is a type of therapy based on the combination of relaxation methods with gradual exposure to the fear (phobia).The objective of the exposure to the fear is that the patient feels progressively less anxious about his/her phobia.In consequence, systematic desensitization increases the feeling of self-control and gradually reduces fear.In conclusion, creating a list of anxiety-triggering situations and training in relaxation are important aspects of SYSTEMATIC DESENSITIZATION.

Which human activity is correctly paired with the greenhouse gas that it increases?
rice cultivation and water vapor
landfilling and carbon dioxide
deforestation and methane
sewage treatment and nitrous oxide
Answer:
land filling and carbon dioxide
Explanation:
landfilling and carbon dioxide human activity is correctly paired with the greenhouse gas that it increases.
What is Landfilling?The emission of methane gas from landfills is the primary environmental issue. Methane gas is generated during the breakdown of organic material in landfills.
Methane is one of the most potent greenhouse gases and a major cause of climate change since it is 84 times more efficient than carbon dioxide at absorbing heat from the sun.
In addition to methane, landfills also release water vapour, carbon dioxide, and small amounts of oxygen, nitrogen, and other non-methane organic molecules. If not under control, these gases can also contribute to climate change and lead to pollution.
Therefore, landfilling and carbon dioxide human activity is correctly paired with the greenhouse gas that it increases.

For the Rock Pocket Mouse, what accounts for the difference in the color of the environment?
Answer:
Changes in the Mc1r gene sequence are not responsible for the colour difference in the mice sampled from New Mexico, however, leading the researchers to conclude that the almost identical dark coat colours developed multiple times in rock pocket mice, an example of convergent evolution.
Changes in the Mc1r gene sequence are not responsible for the colour difference in the mice sampled from New Mexico,
yet, leading the researchers to conclude that the almost identical dark coat colours developed multiple times in rock pocket mice, an example of convergent evolution.
Why are rock pocket mice different colors?
There is natural variation of coat color in the population of rock pocket mice living on the lava flow.
The mutations can cause a change in coat color, and these genetic changes are passed on to offspring.
Thus, due to the Mc1r gene there are difference in the color of the environment.

Answer:
The community will slowly decline, or be just fine, or be better off.
Explanation:
Wolves being killed in Yellowstone showed that Yellowstone suffered, because there was nothing to kill the elk, so their population exploded and they ate everything.
If certain rats were gone in certain areas, then the community/environment would be fine, because rats eat birds and other small animals (they eat too many of them).
And if stray cats were gone then certain forests would be better off and see an increase in birds population, stray cats eat birds.
Where are coral reefs most threatened by pollution, and what effects has pollution had so far?
Answer:
In the great barrier reef
Explanation:
It has effected plants and sea creature populations because of their homes being destroyed
Coral reefs are most threatened by pollution, as they are becoming extinct due to air pollution, water pollution, etc., and then human interference again lets them go extinct, and these reefs that are present in the site of the population are lost mostly.
What is the significance of the coral reefs' extinctions?Coral reefs are negatively affected by pollution and human activities, which include coral bleaching; and again, climate change that is caused by human activities such as the burning of fossil fuels, etc. induces the coral bleaching. Different chemicals that mix with water destroy the corals and the algae present in them.
Hence, coral reefs are most threatened by pollution, as they are becoming extinct due to air pollution, water pollution, etc., and then human interference again lets them go extinct, and these reefs that are present in the site of the population are lost mostly.

O plant; pure water
O animal; pure water
O plant; 3X salt solution
Answer:
Plasmolysis occurs when a plant cell is inmersed in a 3X salt solution.
Explanation:
Plasmolysis is a phenomenon only observed in plant cells, and consists of cell dehydration accompanied by separation of the membrane and cell wall when the cell is exposed in a hypertonic environment.
When a plant cell is in a hypertonic solution —such as 3X salt solution— the permeability of its membrane allows water to escape, so the cell dehydrates and reduces its size. The cell wall is rigid and maintains its shape, but the cell membrane separates from it, which is known as plamolysis.
The other alternative answer combinations are not correct because:
Plamolysis does not occur in animal cells. Pure water does not produce plasmolysis.What is the term for "anything that takes up space and has mass"?
