Test tube baby means a baby born when
Updated On: Jul 11, 2024
- It is developed in a test tube
- It is developed through tissue culture method
- The ovum is fertilized externally and thereafter implanted in the uterus
- It develops from a non-fertilized uterus

The Correct Option is C
Solution and Explanation
By in vitro fertilization, the ovum is fertilized with sperm outside the body of a woman, providing the ovum with the same environmental conditions as it would have got inside the uterus. The zygote is grown inside a culture and when embryo is formed, it is then implanted into uterus where it develops into foetus and then into a child. This is called test tube baby Methodology involves the following steps : - Removal of unfertilised ovum from reproductive tract of a female. - Ovum is kept under aseptic conditions. - Fusion of sperm and ovum in a culture medium, outside the female body to form the zygote. - Zygote is stimulated to develop in vitro upto 32-celled stage. - Developing embryo is implanted on the endometrium of the uterus at 32-celled stage. So the pregnancy in the woman starts and further the development of the child continues in the womb till it is bom.

- An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]

What is a medical abortion?
A medical abortion is a procedure in which procedure is used to end a pregnancy. It does not require surgery and is performed through the ninth week of pregnancy. It involves taking two drugs — mifepristone and misoprostol. Mifepristone drug works by blocking the hormone progesterone and without it pregnancy cannot continue to grow in the uterus. Misoprostol drug causes cramping and bleeding to empty the uterus.
Some differences between the different types of abortions include:
- Medical abortions: A woman will take two different medicines (usually within a 48-hour period). The medication is given by a healthcare provider and is either taken in the provider’s office or at home (or a combination of both).
- Surgical abortions: In this type of abortion, a healthcare provider will surgically remove the embryo from the uterus. These types of abortions require mild sedation, local anesthesia or general anesthesia.
