Answer:
The video says that Tibetan people from birth have higher oxygen saturation due to evolution.
The video says that people in Siberia and the high arctic have adapted to survive extreme cold.
I think that one evolution that could be beneficial to humans is the ability to have more tougher skin because our skin doesn't have too many layers.
Explanation:
Can I have brainliest? It would help me out, if not thanks anyways! Hope this helped and have a nice day! Hope you get an A in that class!!!!
According to the research, the primary purpose of membrane channels is to circulate ions, and of membrane pumps is to maintain differences in ionic concentration.
<h3>What are membrane channels and pumps?</h3>
They are pores in the cell membrane through which ions circulate for muscle contraction or membrane potential changes that may depend on a ligand or voltage, depending on whether their opening is determined by the binding of a ligand or by changes of voltage.
In this sense, membrane pumps is the mechanism of active ion transport, consuming energy across a membrane against an electromechanical gradient to maintain differences in ion concentration between the intracellular and extracellular space.
Therefore, we can conclude that according to the research, the primary purpose of membrane channels is to circulate ions, and of membrane pumps is to maintain differences in ionic concentration.

Are there options too? If yes, then plz provide the options too, the next time you ask :) . Solids would have the lowest kinetic energy and gases have least kinetic energy.
Answer:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
