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

Why do we need cell division?

Answers

Cell division serves as a means of reproduction in unicellular organisms through binary fission. For growth to occur in living organisms, the number of cells have to increase through cell division until it reaches its maximum size. The human body also repairs injuries by means of cell division.

For the Rock Pocket Mouse, what accounts for the difference in the color of the environment?

Answers

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.

What is some of the evidence used by Galileo to support Copernicus’s model and disprove Aristotle and Ptolemy’s?


Each planet spins in an epicycle.

Planets appear to move backward.

Jupiter has moons orbiting it.

The religious and cultural beliefs supported this model.

Answers

Claudius Ptolemaeus (85-165 AD) or Ptolemy believed Aristotle's theory that the Sun, Moon, and planets circled the Earth.

However, he improved it to account for the fact that planets sometimes appear to travel backward across the sky, called retrograde motion.

Galileo Galilei used various pieces of evidence to support Copernicus's heliocentric model and challenge the geocentric model proposed by Aristotle and Ptolemy. Some of the key evidence and observations that Galileo put forward include:

Observations of the phases of Venus: Galileo observed that Venus goes through phases just like the Moon.Observation of Jupiter's moons: Galileo discovered four moons orbiting Jupiter, now known as the Galilean moons (Io, Europa, Ganymede, and Callisto). Observation of Saturn: Galileo observed Saturn using his telescope and noticed the presence of what he called "ears" or "appendages" on each side of the planet.Lunar observations: Galileo's observations of the Moon revealed mountains, valleys, and craters, contradicting the notion of a perfect and unchanging celestial realm put forth by Aristotle and Ptolemy.Sunspot observations: Galileo observed sunspots, dark spots on the surface of the Sun.

Thus, it's worth noting that while Galileo provided empirical evidence to support the heliocentric model, his ideas and evidence faced strong opposition from the religious and cultural beliefs of the time, as they contradicted the established dogma of a geocentric universe.

Describe the control group for an experiment that examines the effect of fire intensity on the biodiversity of tree communities.

Answers

Answer:

explanation below

Explanation:

The control group would be the biodiversity of the trees without the fire

The control group in the experiment would center on the biodiversity of the trees without the fire. Ideally, both the control group and the experimental groups are usually identical in every way except that the experimental group would receive the treatment that is believed to have an effect on the biodiversity of trees.

For an experiment seeking to study the effect of fire intensity on the biodiversity of tree communities, the control group will be an experimental unit consisting of a community of biodiversity of trees with no fire or treatment.

In a scientific experiment, they are usually two main groups of experimental units. They are:

The Experimental Group: This group of experimental units receive the treatment. In the case of the experiment cited above, the experimental group would be a community of biodiversity of trees that is set on fire.The Control Group: This experimental units do not receive treatment. They serve as the basis for comparison. In the scenario cited in the question, the control group would be a community of biodiversity of trees without the treatment, which is, no fire on the community.

Therefore, for an experiment seeking to study the effect of fire intensity on the biodiversity of tree communities, the control group will be an experimental unit consisting of a community of biodiversity of trees with no fire or treatment.

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.

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.
