Question 1

A childless couple can be assisted to have a child through a technique called GIFT. The full form of this technique is

  • Gamete inseminated fallopian transfer

  • Gamete intra fallopian transfer

  • Gamete internal fertilization and transfer

  • Germ cell internal fallopian transfer

Solution

B.

Gamete intra fallopian transfer

The full form of GIFT is 'Gamete Intra Fallopian Transfer'.
The method is used in females who cannot produce ova but can provide suitable environment for fertilization and further development of embryo in the oviducts. In such cases, ovum from the donar female is surgically removed and is then introduced into the Fallopian tube of such females. Such women then accept sperms from her husband during copulation. 

Question 2

A young infant may be feeding entirely on mother's milk, which is white in colour but the stools, which the infant passes out is quite yellowish. What is the yellow colour due to?

  • Intestinal Juice

  • Bile pigements passed through bile juice

  • Undigested milk protein casein

  • Pnacreatic juice poured into duodenum

Solution

B.

Bile pigements passed through bile juice

The stools, which the infant passes out is quite yellowish due to bile pigments passed through bile juice.

Question 3

About which day in a normal human menstrual cycle does rapid secretion of LH (popularly called LH surge) normally occurs?

  • 14th day

  • 20th day

  • 5th day

  • 11th day

Solution

A.

14th day

Rapid secretion of LH leading to its maximum level during the mid- cycle, i.e about the 14th day of menstrual cycle, popularly called LH surge induces rupture of Graafian follicle and thereby the release of ovum (ovulation).

Question 4

Artificial insemination means

  • transfer of sperms of a healthy donor to test-tube containing ova

  • transfer of sperms of a husband to test-tube containing ova

  • artificial introduction of sperms of the healthy donor into the vagina

  • an introduction of sperms of healthy donor directly into the ovary

Solution

C.

artificial introduction of sperms of the healthy donor into the vagina

infertility due to the inability of the male to inseminate the female or due to very low sperm counts n the ejaculates can correct by artificial insemination.

Question 5

At which stage of HIV infection does one usually shows symptoms of AIDS?

  • When viral DNA is produced by reverse transcriptase

  • When HIV replicates rapidly in helper T- lymphocytes and damages large number of these

  • With 15 days of sexual contact with an infected person

  • When the infecting retrovirus enters host cell

Solution

C.

With 15 days of sexual contact with an infected person

HIV enters into T -lymphocytes replicates and produces progeny viruses. The progeny viruses released in the blood other helper T-lymphocytes.This is repeated leading to a progressive decrease in the body of the infected person. During this period, the person suffers from bouts of fever, diarrhoea and weight loss. The person starts suffering from an infection.
