Find the odd one out from the following.

Options:
A Cervical cap
B Lippies loop
C Progestasert
D Multiload 375

The correct answer is:
Cervical cap

Solution:
Physical barriers: cervical cap, diaphragm, condoms, vaults, etc.
In barrier methods, ovum and sperms are prevented from physically meeting with the help of barriers. Such methods are available for both males and females. Diaphragms, cervical caps and vaults are also barriers made of rubber that are inserted into the female reproductive tract to cover the cervix during coitus, while condoms are barriers made of thin rubber/ latex sheath that are used to cover the penis in the male or vagina and cervix in the female, just before coitus so that the ejaculated semen would not enter into the female reproductive tract.
IUDs: Multiload 375, Lippies loop, Progestasert.
IUDs increase phagocytosis of sperms within the uterus and the Cu ions released suppress sperm motility and the fertilising capacity of sperms. The hormone-releasing IUDs, in addition, make the uterus unsuitable for implantation and the cervix hostile to the sperms. IUDs are ideal contraceptives for the females who want to delay pregnancy and/or space children. It is one of most widely accepted methods of contraception in India.
Multiload 375 (Cu releasing)
Lippies loop (non-medicated)
Progestasert (hormone-releasing)

D Saltation - Thomas R Malthus

The correct answer is:
Saltation - Thomas R Malthus

Solution:
Saltation is referred to as a sudden and large mutational change from one generation to the next. Hugo de Vries stated that new species are not formed by continuous variations but through the sudden appearance of variations called as mutations. He believed that mutation causes species formation and thus known as saltation. Based on these observations, he put forward his theory of mutation. Therefore, the theory of saltation was coined by Hugo de Vries.

Fission of nuclei is possible because the binding energy per nucleon in them:

Options:
A increase with mass number at low mass numbers
B decrease with mass number at low mass numbers
C increase with mass number at high mass numbers
D decreases with mass number at high mass numbers

The correct answer is:
decreases with mass number at high mass numbers

Solution:
proportional to the atomic mass of the nucleus.
5. As the mass number increases, the binding energy per nucleon gradually decreases and ultimately binding energy per nucleon of heavy nuclides (such as uranium, etc) is comparatively low. Hence, these nuclides are relatively unstable.
6. Fission occurs generally for elements with high atomic mass.
7. Therefore, we can say that fission of nuclei is possible because the binding energy per nucleon in them decreases with mass number at high mass numbers.
