Describe the electron transport chain including its reactants and products

Answers

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

Where are coral reefs most threatened by pollution, and what effects has pollution had so far?

Answers

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.

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.​

Answers

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.

Alana summarized what happens when a ball sitting on top of a grassy hill rolls down the hill.

The motionless ball has potential energy. Once the ball starts to roll down the hill, new kinetic energy is made. As the ball rolls across the grass, it slows down. The kinetic energy of the ball is converted to other forms of energy.

Which best describes Alana’s error?

The motionless ball does not have energy because it is still.
Kinetic energy is not made; it is a result of energy transformation.
The ball cannot slow down unless someone touches it.
The energy is not converted; it disappears.

Answers

Answer:

It's actually B that guy is wrong on Edge.

Explanation:

Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.

What are the various types of energy?

The law of conservation of energy says that energy is neither created nor destroyed but only converted from one form to another, such as from the kinetic to the potential and vice versa. Here, the ball is placed at the top, where it has no motion, but the ball has potential energy, and that potential energy gets converted into kinetic energy when the ball starts to roll down the hill. After sometime, the ball spontaneously stopped on the ground, and the kinetic energy was converted into potential energy.

Hence, Alana's error regarding the energy of the ball is that kinetic energy is not made; it is a result of energy transformation. The second option is true regarding the energy conversion.

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.

Answers

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.

There are two continents with an ocean between them. Today, the continents have very different plants and animals on them. However, a geologist found fossils of the same type of organism on both continents. Millions of years ago, when this type of organism was alive, we know it lived in only one place. The geologist is using the fossils as evidence to argue that the two continents used to be touching. How could the continents have gotten so far apart, and how long did it take for this to happen?

Answers

Answer:

The continents could have gotten so far because of plate tectonic movement. We know that the plates are always moving so if these plates were very active then it would have caused supercontinent pangea to drift apart. This process must have taken more than a million years to happen.

Answers

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.
