Answer:
The best explanation if we observe an epithelial cell with chromosomes are visible and two cell nuclei is that the cell has just gone through telophase but not cytokinesis (option b).
Explanation:
A somatic cell, when found in mitosis, exhibits the chromosomes distributed in both poles and the outline of two nuclei in the telophase phase, just before cytokinesis.
In mitotic telophase:
- Chromatids, which are chromosomes, are found in the cell poles.
- It initiates the formation of the nucleus membrane.
- The chromosomes begin to turn into chromatin.
- Disappearance of the mitotic spindle, duplication of organelles and cytoplasmic invagination.
The division and differentiation of the nuclei in telophase is called karyokinesis. Later, cytokinesis occurs, where the daughter cells are separated.
The other options are not correct because:
<em> a and d. In the other phases described, </em><em><u>S and G1,</u></em><em> no chromosome distribution is observed at the poles.</em>
<em> c. A somatic cell does not experience </em><em><u>meiosis</u></em><em>.</em>
A couple of the methods of molecular biotechnology are cloning and recombinant DNA.
Answer:
end of cytokinesis
Explanation:
Telophase is the last stage of cell division. It ends with cytokinesis which is the splitting of the mother cells into two daughter cells. The cell pinches in the equator region with the help of a ring of contractile protein filaments. The formed cleavage furrow grows until the two cells pinch off completely.

Reduce osteoblast activity while boosting osteoclast activity
osteoblast:
- Untreated celiac disease has a number of potential side effects, including the failure for children to reach their ideal bone density and adult bone loss, both of which raise the risk of osteoporosis. Following a gluten-free diet is the only way to treat celiac disease.
- As a result, celiac disease is common in both children and adults with low bone density. When celiac disease is discovered in an adult, the risk of osteoporosis is very significant (because they have gone longer without absorbing enough calcium and other nutrients).
- Osteoporosis is a bone disease that appears when bone mass, bone mineral density, or both drop or when the quality or structure of the bone deteriorates. This may result in a loss of bone density and an elevated risk of fractures (broken bones).
