Answer: there is an exchange of chromosome segments between homologous chromosomes during prophase 1
Explanation:
Homologous chromosomes are paired up in their tetrads. Then part of each homologous pair breaks at the same point and reattaches to the other. This results in genetic variation.
Answer: The answer is B. homologous chromosomes join together to form tetrads during prophase I.

how is a strike slip fault different from a normal fault
Answer:
Strike-slip faults are vertical (or nearly vertical) fractures where the blocks have mostly moved horizontally. If the block opposite an observer looking across the fault moves to the right, the slip style is termed right lateral; if the block moves to the left, the motion is termed left lateral.Normal fault describes the downward movement of one side of the fault with respect to the other side

What is the name of the process by which the electron-transport chain generates the electrochemical gradient that drives atp production in the mitochondrion?.
Answer:
oxidative phosphorylation
Explanation:
At the end of this electron transport chain, the final electron acceptor is oxygen, and this ultimately forms water (H20). At the same time, the electron transport chain produces ATP. (This is why the the process is called oxidative phosphorylation.)

Describe three problems caused by rabid human population growth.
Answer:
Well one main and obvious reason would be there wouldn't be enough resources for everyone to use. Another one would probably be air and water pollution would increase immensely. And the last one would be a lot more crimes and political issues? I'm not sure if the last one is valid but the first 2 are definitely counted.
Explanation:
the primary auditory cortex is located in the ________.
Answer:
temporal lobe
Explanation:
The temporal lobe of brain is located in the main auditory cortex.
Thus, in the superior temporal gyrus, which is located on the lateral surface of the brain, it is specially located. A specialized area called the primary auditory cortex is in charge of processing auditory data brought in by the ears.
The auditory pathways provide information, and it analyses different auditory properties including frequency, intensity, and spatial placement. The perception, identification, and interpretation of sound all depend on this area of the brain. The primary auditory cortex helps us detect and comprehend the auditory environment around us by mapping sound signals.

Four substances are involved in both photosynthesis and cellular respiration. They are sugars, water, oxygen, and carbon dioxide. Energy is also transformed from one type to another. Describe what happens to these four substances, light energy, and chemical energy during photosynthesis. Then write a simple equation for the substances and another for energy, using words and arrows to illustrate these changes.
Answer:
Explanation:
The process of photosynthesis is complex. Sunlight energy is converted into chemical energy by using chlorophyll, which is what gives plants their green color. Chlorophyll absorbs red and blue light and uses the energy to convert water and carbon dioxide into glucose then releases the unused components such as oxygen.
Answer:
The four substances recycled during photosynthesis and respiration are carbon dioxide, water, oxygen and glucose.Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
What happens when humans ingest cellulose?
Humans cannot digest cellulose because they lack the enzymes essential for breaking the beta-acetyl linkages. The undigested cellulose acts as fibre that aids in the functioning of the intestinal tract.
THE EFFECT OF SUBSTRATE
CONCENTRATION On Enzyme ACTIVITY
Answer:
Increased substrate concentration increases rate of enzymatic activity.
Explanation:
The more substrate there is for the enzyme to catalyze, the more activity there will be in the reaction. This trend reaches a plateau though, where enzymatic activity levels out after a certain concentration of enzyme is reached.

Why are the average temperatures in the middle of the United States warmer than the coasts? I NEED THIS ANSWER ASAP!
Answer:
Here
Explanation:
The environment of the United States shifts because of changes in scope, and a scope of geographic highlights, including mountains and deserts. By and large, on the central area, the environment of the U.S. becomes warmer the further south one ventures, and drier the further west, until one arrives at the West Coast.
Being near huge amounts of water, such as oceans, lowers the temperature of a site that is just as close to the equator as one without any. As a result, temperatures in the middle of the country rise far more than in coastal states.

identify the structure that regulates the amount of light entering the posterior segment of the eye.
Iris is the structure that regulates the amount of light entering the posterior segment of the eye.
The colored disc-shaped membrane found in the eye of humans and various animals is called the iris.
The pupil appears in the center of the iris: an opening that allows light to enter.It is located behind the cornea, constituting a separation between the posterior chamber and the anterior chamber of the eye.It helps to dilate or contract the pupil to allow more or less light to enter the eye.Therefore, we can conclude that iris is the structure that regulates the amount of light entering the posterior segment of the eye.
