5. Which among the following test is most suitable to judge paternity ?
[A] Blood Grouping
[B] Tissue Culture
[C] DNA Test
[D] Genetic Codes
Show Answer
Correct Answer: C [DNA Test]
Notes:
DNA test is most suitable to judge paternity. It looks at specific locations of a person’s genome, in order to find or verify
ancestral genealogical relationships. It can also be used to estimate the ethnic mixture of an individual.

[C] Root Nodules of leguminous plants
[D] Paddy fields for nitrogen fixation
Show Answer
Correct Answer: A [Human Intestine]
Notes:
Escherichia coli, also known as E. coli, is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia. It is a type of bacteria that normally lives in your intestines.
9. In which of the following part of the cell does the pyruvic acid is broken down into carbon dioxide, water and energy?
[A] Mitochondria
[B] Chloroplast
[C] Nucleus
[D] Cytoplasm
Show Answer
Correct Answer: A [Mitochondria]
Notes:
In Mitochondria, pyruvic acid is broken down into carbon dioxide, water and energy.
10. BCG vaccination is to be given to a new born child after what time?
[A] Immediately after birth
[B] Within 48 hours
[C] Within seven days
[D] Within six months
Show Answer
Correct Answer: A [Immediately after birth]
Notes:
Bacillus Calmette Guérin or BCG is usually given around birth to prevent severe TB in infants. The neonatal immune system is immature. Delaying BCG vaccination from birth to 10 weeks of age would enhance the vaccine-induced immune response. The BCG vaccine is an injection given to children who have a higher risk of catching TB. The BCG vaccine helps your child’s immune system fight the germs that cause TB and helps stop them from getting serious TB disease.
