Answer:

The correct option is: (A) stem cells

Explanation:

The bone marrow is a semi-solid tissue which is generally found in the spongy portions of the bones. In the bone marrow, all the blood cells are produced from the unspecialized precursor cells, which are known as the stem cells. Firstly, the stem cells divide and form the immature blood cells. These immature blood cells then further divide and mature to form the mature blood cells.

Therefore, the stem cells are the precursor cells which transform and mature to form the blood cells.

Anon25 [30]
The best fossil evidence to suggest that Neanderthals could produce a language like that of modern humans comes from the “hyoid bone” collected at Kebara Cave in Israel. Because of the descended larynx, it may be indicated that Neanderthals are capable of human-like speech.
