Answer 1

Q. No. 35. Answer : is " a ".

Because it is autosomal recisive disorder.

Which is caused by mutations in both alleles of the gene phenylalanine hydroxylase, which is found on chromosome 12.

So the answer is " a ".

Q. No. 36 answer : is " a ".

Because the blood will carries oxygen, when the blood supply is decreases automatically the oxygen supply decreases to the cardiac muscles, it leads to necrosis and damage of cardiac muscle.

So the answer is " a ".

Q. No. 37. Answer : is " c ".

Because here the transient spasm of the coronary arteries leads to deficient blood supply to the heart.

And decreased oxygen supply leads to pain in heart so it is called as myocardial infarction.

If pain is in the chest means we can called Angina pectoris.

So the answer is " c ".

Q. No. 38 : answer is " c ".

Because it is also known as idiopathic hypertension.

So the answer is " c ".

The cause is unknown may be age and sex causes.
