bisphosphoglyceric acid (bpg) is a byproduct of glycolysis released into the bloodstream when an animal's supply of oxygen is lo
valentina_108 [34]

When an animal's oxygen supply is limited, bisphospoglyceric acid increases the oxygen level by acclamitization.

Acclimatization is the term used to describe the advantageous physiological changes brought on by frequent exposure to a hot climate. Increased sweating effectiveness is one of these physiological modifications. It is converted into a molecule identical to that of 2,3-bisphosphoglyceric acid (2,3BPG). A mechanism called 2,3BPG is employed to control the effective emission of oxygen from haemoglobin. As one of the processes of acclimatization, 1,3-BPG levels will rise in a patient's blood when concentration is low. Low oxygen levels increase 1,3BPG levels, which in turn increase 2,3BPG levels and change how well oxygen separates from hemoglobin.

The number of differences between cytochrome c of humans and cytochrome c of other organisms is as follows: Rhesus monkey - 1 di
liubo4ka [24]

Answer:

The species that will be most similar to humans will be

1. rhesus

2. pigeon

3. fruit fly

Explanation:

Evolution can be described as the process in which different organism evolve from common ancestors over a long period of time. Evolutionary studies show that some organisms have more shared characteristics as compared with other organisms. These organisms with common characteristics are believed to be closer to one another and evolved from the same ancestors.

In the above question, as there is only one difference between the cytochrome c of humans and rhesus, hence rhesus is the closest to humans. Pigeons has lesser number of differences than fruit fly, hence it is second on the list. Fruit fly has the maximum differences hence it is placed last.
