Internal and external factors regulate cell division
Explanation:
Internally, hormones act as cell signals to regulate cell division. Thyroid hormone, for example, plays a role in regulating cell growth and division in the body. When the hormone is produced in higher concentrations by thyroid glands, it spurs cell division and vice versa.
External factors include aspects like nutrition. If the cell is able to gather enough nutrition from its environment, then it is capable of carrying out several cycles of cell division. However, when resources are limited, cell division is limited to a few cycles. This is why denying babies good nutrition during their early childhood results in stunted growth.

Answer: Replication is called semiconservative because each of the original strand is is used as a template for the synthesis of a new strand
Explanation: DNA is a double-stranded helix containing two antiparallel strands that are complementary to each other.
Replication is the process of making identical copies of a DNA molecule. Before replication begins, the double-stranded DNA is first unwound by helicase so that each strand will serve as a template for new strand synthesis.
DNA replication is semiconservative because each DNA strand serves as a template for the synthesis of a new strand, producing two new DNA molecules each one with one new strand and one strand.
