The process of cellular respiration is essential for energy and it takes places in the mitochondria of the cell. The reason why mitochondria are known to be the power house of a cell.

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.
Answer: True
Explanation:
Renin ( angiotensinogenase), is an aspartic protease protein which is secreted by kidney that participates in the body's renin – angiotensin – aldosterone network that mediates arterial vasoconstriction and extracellular fluid volume.
Renin is released by cells of the juxtaglomerular apparatus in response to the stimuli of decrease in arterial blood pressure and the degree of stretch of the arteriole wall.
Hence, the statement is true.
The body controls this process of puberty through release of hormones, leutenizing hormone and follicle stimulating hormone for the development and maturity of the testes and sperm cells. also androgens will be released and are responsible for the male secondary sexual characteristics such as breaking vice and hair presence under the armpits and the pubic area<span />
