You examine an epithelial cell (skin cell) and notice the chromosomes are visible however it appears there are two nuclei in the
krek1111 [17]

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>

2. Suggest two ways that reflex reactions help maintain homoeostasis in the human body.
Nata [24]
<span>One reflex reaction to maintaining homeostasis in the body is shivering. In response to cold temperatures, the muscular system moves our muscles quickly to warm them up as a rapid, short term solution for homeostasis. Another example is the withdrawal reflex, which occurs as a response to pain. Pain receptors activated by the painful stimulus activate the motor neurons in the body, which in turn contract muscles to move parts of your body away from the pain.</span>
