Why do so many (~30%) gorilla babies die within the first few months of their lives?
katrin2010 [14]

(30%) gorilla babies die within the first few months of their lives because of inherent weakness of the infant or disease.

What is inherited disease?

Genetic factors play a role in almost all health conditions and traits, but there are some conditions in which genetic alterations play a role in almost all of the causes that cause the condition.

Genes are passed from parent to child, so are DNA changes within the gene. DNA changes can also occur spontaneously, first appearing in children of unaffected parents. This is called a new mutation, and the word mutation means change.

Therefore, (30%) gorilla babies die within the first few months of their lives because of inherent weakness of the infant or disease.

Autonomic dysreflexia is characterized by a. hypotension and shock. b. hypertension and bradycardia. c. pallor and vasoconstrict
omeli [17]

Answer:

B) hypertension and bradycardia.

Explanation:

Autonomic dysreflexia is a syndrome which is characterised by the sudden rise in the blood pressure of the human. The disease is common in the people with a higher level of spinal cord injuries above the T6 level.

The condition occurs when some external stimuli like pain or irritant activate the involuntary response in the body which cause the blood pressure to rise (hypertension). This leads to the slowdown of the heartbeat (bradycardia) to restore the blood pressure but the body cannot restore the blood pressure due to the damage in the spinal cord.

Thus, Option-B is the correct answer.
