Answer:
<em>The correct option is C) Cells do not use the same sections of DNA in the same proportions, at the same time in development, which leads to differentiation.</em>
Explanation:
All the cells in an organisms body comprise of the same DNA. However, each cell is specialized to perform a different function because a part of the DNA which is active in one cell might not be active in the other cells. In this way, cell differentiation occurs. The genes which are being transcribed in one cell type may be completely repressed in the other cell type. As a result, variations occur in the structure and function of different cells.

Answer: The correct answer is- testes → epididymis → vas deferens → urethra.
Sperms are the male reproductive cells that are produced during spermatogenesis ( process of gamete formation in males).
Sperms are produced in seminiferous tubule ( that lie within testes) and the they migrate to epididymis ( where they are stored and matured). Sperms travel from epididymis to a muscular tube that is called vas deferens. Finally, sperms are propelled towards urethra via ejaculatory duct.
Answer:
a
Explanation:
plants uses oxygen for respiration, so in that process respiration takes place and respiration in plants has to do with the conversion of oxygen to carbon dioxide which serves as a means of respiration and during respiration ATP is being produced which stands for Adeosine triphosphate
