Describe the electron transport chain including its reactants and products
Answer:
The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.
Explanation:
The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.8

if one species in a community dies out or moves, the community will
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.

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.

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.

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.

All of the aforementioned statements regarding fossils are true except: B. Amber-preserved fossils are the most common form of fossils and are actually the least helpful in studying organisms.
What is a fossil?A fossil refers to the mineral impression or remains of both living and non-living organisms that are generally considered to be prehistoric in nature.
This ultimately implies that, fossils are obtained from ancient organisms such as H-o-m-o Erectus, which is an organism that could walk on two (2) feet like humans.
However, amber-preserved fossils are actually very helpful in studying organisms that are generally considered to be prehistoric in nature.

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 is not a function of the respiratory system? *
It warms air entering the body.
O It exchanges oxygen and carbon dioxide.
O It pumps blood to the organs.
O It creates sound through the voice box.
Answer:
it exchanges oxygen and carbon dioxide
Explanation:
You inhale oxygen and exhale carbon dioxide
Out of the given options 3 that is "it pumps blood to the organs" is not a function of the respiratory systems.
The respiratory system is a network of organs and tissues that assist you in breathing. This system assists your body in absorbing oxygen from the air so that your organs can function.
It also removes waste gases from your blood, such as carbon dioxide. Allergies, illnesses, and infections are common difficulties.
The respiratory system contributes to the warming and humidification of the air we breathe. The air is warmed as it goes through the nasal passages and pharynx, which helps to protect the lungs' sensitive tissues.
The respiratory system contributes to the production of sound. When air flows through the larynx (voice box), the vocal cords vibrate, producing sound.
Thus, the option 3 is not the function of the respiratory system.
