Using a molecular clock, scientists are able to estimate the amount of time that two species have been evolving independently.
Hope this helps :)

Answer:
c) Gives a cell its distinctive characteristics
Explanation:
Carbohydrates perform two main functions in the cell's membrane: <em>they participate in cell recognition and adhesion</em> (cell-cell signaling or cell-pathogen interactions), they also have a structural role as a physical barrier.
Most of the carbohydrates linked to the membrane are in the form of <em>glycoproteins oy glycolipids</em>, these are the molecules that share information and recognize host cells. <em>Glycocalyx </em>is another way we find carbohydrates in the cell membrane, this layer has cell-adhesion molecules that enable cells to adhere to each other.
I hope you find this information useful! Good luck!
Answer: I think the answer is c
Explanation:
The condition of acidosis can also cause hyperkalemia because the higher H+ concentration diffuses to the intracellular fluid, pushing K+ towards the extracellular fluid.
Hyperkalemia describes a potassium level in the blood which is higher than normal. Potassium is a vital substance to the function of nerve and muscle cells, including those of the heart. Blood potassium is normally 3.6 to 5.2 millimoles per liter.
