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,

Photosynthesis: Photosynthesis is an enzyme regulated anabolic process of manufacture of organic compounds inside the. chlorophyll containing cells from carbon dioxide and water with the help of sunlight as a source of energy.
Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion
Explanation:
Transport proteins generally perform two types of transport: “facilitated diffusion,” where a transport protein simply creates an opening for a substance to diffuse down its concentration gradient; and “active transport,” where the cell expends energy in order to move a substance against its concentration gradient
The “powerhouses” of the cell, mitochondria are oval-shaped organelles found in most eukaryotic cells. As the site of cellular respiration, mitochondria serve to transform molecules such as glucose into an energy molecule known as ATP (adenosine triphosphate).
