Answer: option B) False
Explanation:
The body relies on SEVERAL sources for its energy or glucose supply.
Firstly, understand that Glucose could be supplied from the following:
Glycogenolysis (Glycogen break down induced by Glucagon)
Amino acids metabolism (once amine group is removed)
Fatty acid oxidation.
All of the pathways mentioned can directly or indirectly yeild GLUCOSE, thus making it UNNECESSARY for Carbohydrate meals to be consumed every 3 to 4 hours.
Therefore, the answer is False
Answer:
B. Produce cells that are genetically identical to one another
Answer:
1. deoxyribonucleic acid, a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
2.the material or protoplasm within a living cell, excluding the nucleus.
3.a microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence.

Answer:
B) Na+
Explanation: Na+ molecule is polar, oxygen and carbon dioxide are nonpolar molecules. The cell membrane is a <em>phospholipid bilayer</em> made up of lipid molecules with polar and nonpolar ends. Since it is a bilayer, two phospholipid layers are arranged, one on the other in such a way that one faces the back of the other. The non polar ends are away from outside and inside of the cell, while the polar ends faces towards all the molecules inside and outside the cell.
Since polar-polar molecules repel each other, Na+ can't pass through the cell membrane easily. So it uses the proteins attached the cell membrane inside and outside to transport such molecules by using energy in terms of ATP.
