Hello there!
Your answer should be ATP is a stored form of energy.
You see, Think of it as the “energy currency” of the cell. If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell. Hope this works!
I believe the answer for this would be B. Just using the process of elimination knocks out D and A, and plants make carbs not protein during photosynthesis :)
Answer:
The correct option is <u><em>A. they evolved from land mammals.</em></u>
Explanation:
The process of evolution explains how closely one organism is to another based on their common ancestors. Scientists believe that those organisms which show many similarities in their structures or functions might have evolved from a common ancestor in the past.
As in the above-mentioned question, scientists have observed that cetaceans lack gills and breath air, this is a property of land mammals. The cetaceans have fin bones which are similar to the limb bones. As limb bones are present in land mammals, hence they cetaceans and land mammals might have common ancestors in the past.
The answer would be c. only plant cells and some single cell organisms photosynthesize.
Since this is college level biology, you should know that red blood cells do not contain organelles... therefore it does not do a,c, and d. So, the question should say, which of the following is correct.
