Answer:
(C) maleness results from the minimal presence of one Y chromosome
Explanation:
Human males have one Y and one X chromosome as their sex chromosomes. However, the human males with Klinefelter (XXY) syndrome have two copies of X chromosome as the human males but also have one Y chromosome. Similarly, human females have two X chromosomes as sex chromosomes but the females with Turner (XO) syndrome have only one X chromosome and the females with poly-X (XXX, XXXX) have more than two X chromosomes.
This means that the Y chromosome regulates sex in human beings. If one copy of the functional Y chromosome is present in the cells, the fetus will develop into a male. The absence of a functional Y chromosome will make the fetus develop into a female.

Answer:
See the answer below
Explanation:
Person X is feeling a burning sensation in several muscles<u> because of the accumulation of lactic acid due to inadequate oxygen in their system.</u> When oxygen becomes inadequate during exercises, anaerobic respiration takes place to augment the oxygen shortage and this leads to the production of lactic acid which accumulates up in the muscles and gives a burning sensation.

Person Y does not feel any burning sensation in their muscles <u>because oxygen is adequate in their system and they do not need to respire anaerobically.</u> <em>Person X exercise regime must have been more rigorous than that of person Y.</em>
