Answer:
c)peptidoglycan synthesis and cell walls
Explanation:
The main points of action of antibiotics are inhibition of bacterial cell wall peptideoglycan synthesis, cytoplasmic membrane damage and interference with nucleic acid and protein synthesis.
The bacterial cell wall is formed by peptideoglycan. Penicillin and other antibiotics prevent its complete synthesis, consequently weaken the cell wall and the cell lyses. Because human cells lack peptideoglycan, penicillin has low toxicity to the host cell. The synthesis of peptideoglycan components is affected by β-lactam antibiotics (penicillins and cephalosporins).
For this reason, we can conclude that the antibiotics described in the above question are those that target peptidoglycan and cell wall synthesis.
Answer:
The reason is because the heart requires more oxygen when exercising. Several physiological events happen to increase the blood flow and therefore oxygen flow to that muscles,including the heart.
Also the volume of blood that the heart pumps out is maintained so that the body organs receive the necessary amount of oxygen and nutrition, because if it didn't adjust the flow of blood to match activity level, you will be insufficient. Either output method will be lower than needed.

Explanation:
The substance that provides immediate energy is adenosine triphosphate (ATP). ATP is called the energy currency of the cell, and is hydrolyzed to produce adenosine diphosphate and a phosphate group.
ATP is obtained by break down of carbohydrates, fats as well as proteins.
