Answer:
The white blood cells i.e. granulocytes and macrophages are specifically stimulated by GM-CSF in response to chemotherapy in cancer patients.
Explanation:
The colony stimulating factors (CSFs) are the regulators of granulocytes and macrophages in blood. The CSFs has the potential to regenerate the white blood cells damaged during chemotherapy. Thus, CSFs mobilize the stem cells to enhance the immune process and produce hematopoietic cells such as granulocytes, macrophages in cancer patients. The CSFs resemble hormones that are specifically targeted to produce blood cells in specified regions where the quantity of those cells is low. The CSFs belong to a group of regulatory factors also known as cytokines and does not produce only a single cell type but stimulates colonies of different blood cell types for any specific organ. Hematopoietic cells produced by CSF are step-wise and formation of blast colonies take place initially. Afterwards, the blast cells regenerate and differentiated into multiple progenitor cells consisting of granulocytes, monocytes, macrophages, eosinophills, erythroids, and lymphocytes. The progenitor cells in the granulocyte-macrophage lineage matures into neutrophilic granulocytes and macrophages.
Out of all types of CSF colonies, the Granulocyte-Macrophage (GM-CSF) colony is specially involved in regenerating immune responses in cancer patients. These cytokines stimulates the dendritic cell formation and produces dendritic activity against the cancerous cells. These GM-CSF colonies enhance the immune response of host against melanomas, tumors by reducing their growth and inducing remission. Hence, it can be said that granulocytes and macrophages are infection protective cells and elevates dangerously low levels of white blood cells in cancer patients following chemotherapy. The GM-CSF induction regenerates the bone marrow which is damaged and improves stem cells production.

Answer: B. Sarcoplasmic reticulum
Explanation: The sarcoplasmic reticulum is the name given to the organelle in the muscle cell, in charge of the storage and regulation of the intracellular calcium levels. It is the smooth endoplasmic reticulum in muscle cells, it means that it does not have ribosomes in its surface.
Option A. Incorrect. A SARCOMERE is the functional and anatomic unit of the striated muscle (skeletal muscle and heart muscle). This word comes from the greek: <em>sarkos (meat), meros (part). </em>That is reason you could find other structures of the muscle cell with this root (SARCO...).
Option C. Incorrect. "Arcolemma" this word does not exist. But if it refers to SARCOLEMMA, this word means: <em>sarko (meat), lema (cortex) </em>in greek<em>. </em>It is the plasma membrane of the muscle cells.
Option D. Incorrect. The SARCOPLASM, comes from the greek: <em>sarko (meat), plasm (matter). </em>This structure is the citoplasm of the muscle cells.
In conclusion, the word SARCOPLASMIC RETICULUM, refers to a <em>structure of the muscle cell, </em>that in this case, is the RETICULUM or the SMOOTH ER.
