Answer: Option 'C' is correct.

Explanation:

Every cells change with ageing.

As cell age they tend to become larger and as the body ages it tends to have fewer cell dividing.

As the age of cells increases, cells become less able to divide and multiply.

Due to which when an middle aged or old aged person get wounded, their healing takes so much of time as compare to child because new cells do not develop easily in old age people. It takes time to develop new cell to heal their wound.

Hence, option 'C' is correct.

Answer:

option D, smaller; fewer cells dividing

Explanation:

With aging a cell's performance slows down and after a certain period of time it dies. In this way several cell die in an aging person , thereby making an organ less functional.

The number of living and functional cells in testes, ovaries, liver, and kidneys decreases markedly with aging.

As a cell dies, it shrinks and reduces in size thereby expelling liquid out of it.

Also the rate of formation of new cells reduces with progressing age.

Therefore, as a person becomes old the cell reduces their size and hence die. Also the cell division process becomes slow

Option D is correct

Radda [10]

Answer:

Considering that homeostasis is restored in the patient, his blood pH range would return to normal levels (7.35-7.45), and his hydrogen ion concentration in the blood would normalize. The effect of normalizing the body by getting rid of excess hydrogen ions is achieved by concentrating these ions into the urine for expulsion, therefore increasing the pH levels of urine.

Explanation:

Acidosis is the condition wherein excessive acid build-up within the body causes the blood pH to become lower than normal (normal pH range 7.35-7.45). This may be due to an excessive loss of bicarbonate in the blood, also known as metabolic acidosis, or due to an impairment in the elimination of carbon dioxide in the blood from poor lung function, also known as respiratory acidosis. The body's natural response to acidosis is to increase the breathing rate to eliminate carbon dioxide in the blood, restoring the natural pH of the body.

In people with diabetes mellitus type I, the lack of insulin causes cells to breakdown fat aside from glucose as an energy source. This process produces ketones as a metabolic by-product for energy but also causes the body to be acidic. This is known as diabetic ketoacidosis.

Serjik [45]
<span>Three months after fertilization and development of a placenta around the developing fetus, the corpus luteum regresses and forms the corpus albicans.</span> Formed placenta takes over progesterone production (which was the role of corpus luteum) and the corpus luteum degrades into a corpus albicans. The corpus luteum is being broken down by macrophages, in a process called luteolysis. The remains of the corpus albicans may persist as a scar on the ovary.
