Answer:

When a nerve cell is stimulated, the cell membrane becomes MORE permeable to Na+.

Explanation:

When the action potential is fired, opening of Na+ ion channels in membrane makes it more permeable to the Na+ ions. The Na+ ions enter the axon and makes the inside of the membrane more positive. This is called as depolarization. Depolarization of axon is followed by depolarization during which K+ ion channels are opening to allow movement of K+ ion outside the axon and to make the inner side of axon membrane negative again.

Answer:

The answer is "Photosynthesis creates glucose (sugar) which is used in cellular respiration."

Explanation:

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration. We breathe in that oxygen, which is carried through our blood to all our cells. In our cells, oxygen allows cellular respiration to proceed. Cellular respiration works best in the presence of oxygen. Without oxygen, much less ATP would be produced.

During DNA replication:
Anna [14]

Answer:

f. Methylation of the DNA is maintained because methylation enzymes act at DNA sites where one strand is already methylated and thus correctly methylated daughter strands after replication.

Explanation:

DNA methylation is the addition of methyl group to DNA.it is an example  of EPIGENTICS mechanism  in genetics( epigentic refers to modification of expression of genes instead of altering the gene codes),

The objective of this mechanism is to modify the  function of the particular GENE, therefore affecting the expression of the gene,
