In order to test hypotheses about natural selection favoring stripes in zebras or otherwise, researchers will have to assume that stripe colors are heritable in zebra.

<h3>Natural selection</h3>

Natural selection forces only act on heritable traits/genes so as to help organisms adapt to changes.

Traits that are developed as a result of the environment without any underlining genes are not heritable and cannot be selected or deselected by natural selection forces.

Living cells cannot use heat to provide the activation energy for biochemical reactions because ________. Which choice(s) comple
postnew [5]

Considering the following;

I. Heat is not readily available to all living cells.

II. Heat at excessive amounts denatures proteins.

III. Heat does not provide the activation energy for their reactions.

IV. When a critical temperature is reached, proteins no longer function

Answer;

I and IV

Explanation;

Living cells cannot use heat to provide the activation energy for biochemical reactions because heat is not readily available to all living cells and also when a critical temperature is reached, proteins no longer function.

Too much heat can kill an organism by rendering its organelles, cells, tissues and organs permanently inoperable and un-salvageable. The same process can be observed in tissues at low temperatures, and is the cause of frostbite. This is because enzymes are denatured by high temperature and inactivated by low.

1. How does the body adjust to a higher altitude?
Anni [7]

During acclimatization over a few days to weeks, the body produces more red blood cells to counteract the lower oxygen saturation in blood in high altitudes. Full adaptation to high altitude is achieved when the increase of red blood cells reaches a plateau and stops.Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). ... At the beginning of exercise, your body removes the parasympathetic stimulation, which enables the heart rate to gradually increase.
