Explanation

$\textbf{Correct option:}$

$\textbf{(C)}$

$\textbf{Solution:}$

$\bullet$ IVF (In vitro fertilisation) is a technique of fertilisation of ovum with sperm and this process is carried outside the body of female in a glass container in a culture medium (In vitro).

$\bullet$ Either zygote or early embryo is transferred at 8 celled or blastomere stage in the fallopian tube and this process is known as ZIFT (Zygote Intra-Fallopian Transfer).

$\bullet$ This technique helps the infertile couple to solve their infertility problems.

Bull semen for the purpose of artificial insemination is stored in

0%
Ice
0%
Liquid oxygen
0%
Liquid nitrogen
0%
Liquid CO $_2$

Explanation

Artificial insemination is a globally accepted method of breeding cattle and is also effective for other species. Semen can be stored deep-frozen in liquid nitrogen, in a chilled liquid form or at room temperature. Its low temperature of

$-196^0$ C and inert caracteristics prevent the deterioration of biological quality. Hence, option C is correct.

The term test tube baby implies that

0%
Fertilization of ovum takes place in the uterus but develops in the test-tube
0%
Fertilization of ovum takes place in the test-tube but it develops in the test-tube itself
0%
Fertilization of ovum takes place in the test-tube but it develops in the uterus
0%
Fertilization of ovum takes place in the uterus and embryo develops in the uterus

Explanation

$\textbf{Correct option:C}$

$\textbf{Solution:}$

$\bullet$ When couples are unable to conceive a child due to incurable disorder ,then they are assisted through some special technologies to have children .These are commonly known as Assisted Reproductive Technologies(ART).

$\bullet$ IVF stands for in vitro fertilization. In this process,ovum is collected from the female and sprm is collected from the male,and these gametes are fused to form a zygote outside the body in almost similar conditions as that found in the female body.

$\bullet$ When the zygote produced after the fusion of collected gametes is let to divide several times to create 8 blastomeres ,at this stage it is transferred to the fallopian tube this is known as ZIFT (zygote intra fallopian transfer ).

$\bullet$ Intrauterine transfer is when the zygote divides to produce more than 8 blastomeres stage then it is directly transferred to the uterus.

$\textbf{Hence, the correct option is (C)}$

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

0%
Germ cell internal fallopian transfer
0%
Gamete inseminated fallopian transfer
0%
Gamete intra fallopian transfer
0%
Gamete internal fertilization and transfer

Explanation

$\textbf{Correct option:}$

$\textbf{(C)}$

$\textbf{Solution:}$

$\bullet$ GIFT stands for Gamete intra fallopian transfer, an assisted reproductive technique that helps the childless couples to have the child.

$\bullet$ It involves the transfer of an ovum collected from a donor into the fallopian tube of another female.

$\bullet$ This technique is develop for the female who cannot produce one, but can provide suitable environment for fertilisation and development of embryo.

Artificial insemination means

0%
Transfer of sperms of a healthy donor to a test tube containing ova
0%
Transfer of sperms of husband to a test tube containing ova
0%
