Some differentiated cells become senescent almost immediately, leaving the cell cycle and undergoing terminal differentiation. Other cells have a high need to proliferate in order to grow and repair the organ or tissue, so they do not enter senescence for a long period of time. Which cell type would be most likely to put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair?
brain cells

lung cells

skin cells

heart cells

Answers

Answer:

skin cells.

Explanation:

for connexus friends

The cell that will most likely put off senescence and terminal differentiation so it could continue to replicate in order to grow and repair would be skin cells.

The skin is a tissue whose cells are constantly dividing to replace old, damaged, or worn-out cells.

Damaged, and worn-out cells are frequent on skin tissues because they directly interact with the environment, exposing them to mechanical, chemical, and other forms of damages.

Thus, the skin cells cannot afford to go into senescence or terminal differentiation due to the fact that they need to constantly divide and replace damaged ones.

Diploid
Haploid
Description
Homologous chromosome pairs
Designated N
Designated 2N
Has one member of each
homologous chromosome pair
Includes gametes
Includes somatic cells
Heart and liver cells
Sperm and Egg cells

Answers

Answer:

Please find the description and it's pair below:

Homologous chromosome pairs - DIPLOID

Designated N - HAPLOID

Designated 2N - DIPLOID

Has one member of each

homologous chromosome pair - HAPLOID

Includes gametes - HAPLOID

Includes somatic cells - DIPLOID

Heart and liver cells - DIPLOID

Sperm and Egg cells - HAPLOID

Explanation:

1. Diploid organism is an organism with two sets of chromosomes, with each set contributed by each male and female parent. Chromosomes from the male parent is found side by side with chromosomes from the female parent to form HOMOLOGOUS CHROMOSOME PAIR in a diploid organism. Diploidy is denoted by 2N, where N represents number of one set of chromosomes. Diploid cells include somatic or body cells such as heart and liver cells.

2. Haploid organisms are organisms that contain one set of chromosome, formed as a result of meiotic division of diploid cells. Hence, a haploid cell contains one member of each homologous chromosome pair. Haploidy is denoted by N, meaning number of one set of chromosome. Haploid cells include gametes or sex cells such as sperm and egg cells.
