QUESTION 58

1. Menstruation is part of the uterine cycle. Why does it happen?

   	A.	Scientists have not entirely explained why women menstruate.
   	B.	When an egg is released, the endometrium or uterine lining develops to support an embryo in case of pregnancy. If pregnancy does not occur, the lining is shed.
   	C.	When an egg is released, there is also a release of endometrial fluid from the ruptured follicle. This must be shed in order to prepare the uterus for possible pregnancy.
   	D.	The corpus luteum secretes estrogen and progesterone, causing development of the endometrial ovarian lining in preparation for possible pregnancy. If no pregnancy occurs, hormone levels plummet and the lining is shed.
   	E.	Estrogen levels increase at ovulation, causing the development of the endometrial vaginal lining in preparation for pregnancy. If there is no pregnancy, the lining is shed.

Answer 1

56) c) to look for risky sexually transmitted diseases  

Because some diseases like hiv ,hepatitis b, are chronic diseases which have no cure and these are transfmitted through blood, and sexually and through fluids so, doctors check the blood to have an idea about the diseases .and also to find the chromosomal disorders in the blood of the foetus.

A doctor does urine tests along with blood tests so, this option is eliminated.

Actual Pregnancy is known by urine tests only, becsuse human chorionic harmone is present in the urine of mother .with this presence only we can identify that she is pregnant. So, this is eliminated.

A doctor doesn't do blood tests to prove his father.

57) d) equal probability to both man and a woman Is correct.

Because there are 50% chances to both of them .

Always the problem doesn't lie particularly in either man or woman, so c) and e) are eliminated.

And moreover the cause is determined, it is quite natural. And it can happen by the combination of the two in some cases.  

58) b) when egg is released, the progesterone level increases which leads to the development of endometrium for the protection of baby in case if pregnancy. But when fertilization doesn't occur it leads to the shedding of the endometrium, and this is menustration.

Scientists completely explained about menustration.

And moreover endometrial fluid is not present in the egg to be released at the time of menustration.

Progesterone leads to the development of endometrium not the estrogen. So, estrogen doesn't develop endometrial vaginal lining so, d) option is eliminated.

E) is eliminated because corpus leutum doesn't secrete estrogen .

It releases only progesterone.

59)

D ) intravaginal insemination is correct answer because the term insemination means transfer of sperm from male donor.

And it is clearly mentioned that sperm is directly inserted into female vaginal tract so, the answer is intravaginal insemination.

Term artificial insemination means the semen is injected into the uterus or fallopian tube.

Artificial fertilization means fusion of sperm and egg.

C) invitro fertilization means fusion of both gametes in external conditions ( lab conditions)

60)

A) harmonal conception pills contain both estrogen and progesterone because these harmones are very necessary. And estrogen and progesterone harmones inhibit the release of lutinising and follicle stimulatind harmones from the pituitary of the brain. These stimulating harmones are necessary for the development of endometrium and release of egg.

Testosterone is not at all related because it is a male harmone.

FSH is also not related because it is not a harmone, it stimulates a harmone.

Chorionic growth harmone acts as pregnancy harmone but not as contraceptive.

61) apgar means appearance pulse, grimace, activity, respiration.

E) option is correct because it tells about how the mother delivered the child in healthy conditions.

It tells about the skin color, heart rate,reflex irritability, muscle tone and breathing rate.

And moreover doesn't give information about chromosomes .as such pku ( phenyl ketonuria) is chromosomal disorder. so , it is not known by the apgar.

Also apgar doesn't tell about eye infection.

Tells only about Child's health.
