C) they store energy for the cell
Sea levels<span> drop globally </span>during an ice age<span> (also called a glacial period) as seawater is taken up in the </span>ice<span> sheets. There is decreased evaporation </span>during an ice age<span> and therefore less rain. </span>Ice ages<span> (also called glacial periods) are therefore usually, but not always, associated with an increase in aridity (dryness). So its B. Hope this helps :))</span>
Answer:
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.
Explanation:
Peptidoglycan is present in the cell wall of gram-positive bacteria. Bacteria are safeguarded by a robust cell wall comprising peptidoglycan. The layer of peptidoglycan in the cell wall of bacteria refers to a crystal lattice composition produced from linear chains of two alternating amino sugars, that is NAM (N-acetylmuramic acid) and NAG (N-acetylglucosamine). Peptidoglycans is one of the most essential sources of D-amino acids in nature.
