Answer:
No, because a cell wall is only present in plant cells and is located outside the cell to give it structure.
Answer:
exergonic; endergonic.
Explanation:
Exergonic reactions may be defined as the reactions in which the energy is released during the reaction. Endergonic reaction are the reaction in which energy is required for the occurrence of reaction.
Catabolism reaction in which the large substance is broken down into simpler substance. Large amount of energy is released during the reaction and considered as exergonic reaction. Anabolism reaction in which small substance combine together to form a large molecule. A large amount of energy is required in this reaction and considered as endergonic reaction.
Thus, the correct answer is option (b).
Answer:
The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.
Explanation:
I believe the first one is faster and the second one is smaller. Hope this helps. :)
Answer:
The return of blood to the heart is assisted by the action of the skeletal- muscle pump. As muscles move, they squeeze the veins running through them. Veins contain a series of one-way valves, and they are squeezed, blood is pushed through the valves, which then close to prevent backflow.
