Answer:
it exchanges oxygen and carbon dioxide
Explanation:
You inhale oxygen and exhale carbon dioxide
In spherocytosis, there is a defect in the membrane proteins of the red blood cells, specifically ankyrin and spectrin. These membrane proteins contribute to the biconcave shape of red blood cells therefore the loss of these proteins will lead the red blood cells to lose its biconcave shape--leading to abnormally shaped red blood cells (spheres) hence the name. This can lead to premature destruction of red blood cells and jaundice due to hyperbilirubinemia. Spherocytes do not hold oxygen and carbon dioxide well as spherocytes have a decreased surface area.
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>
The cell is the smallest functional unit of life, which is why it is sometimes referred to as the building block of life.
When there is myelosuppression, the suggestive finding is
there is a decrease in the platelets and red blood cells. Also called the bone
marrow suppression, myelosuppression is a common side effect of the treatment
of chemotherapy. When this side effect happens, there is a decrease in the production
of blood cells. The result which may be the effect of myelosuppression is a
decrease in one, two or all three types of blood cells. Most patients of
chemotherapy experience a decrease in red blood cells. Another effect is the
decrease of white blood cells by most patients. Myelosuppression will be
subcategorized as neutropenia when chemotherapy results to the reduction of
neutrophils which is a specific type of white blood cells. Thrombocytopenia is
the term for a drop in platelet numbers. This kind of suppression is not that common. Only 10 percent of cancer patients undergo
the negative effects of this kind of suppression.
