Show Answer
Correct Answer: A [Basin Era]
Notes:
Basin Groups refers to 9 subdivisions of the lunar Pre-Nectarian geologic period. It is the second era of the Hadean. In Basin Era began the Self-replicating RNA molecules on Earth.

[A] Anuria
[B] Aplastic Anemia
[C] Pernicious Anemia
[D] Aplasia
Show Answer
Correct Answer: B [Aplastic Anemia]
Notes:

[D] Solanum melongena
Show Answer
Correct Answer: B [Rhizophora]
Notes:
Allium cepa is onion.
Solanum tuberosum is potato,
Solanum melongena is Brinjal.

10. The Trans-fats cause problems in human body because__:
[A] The fat molecules contain high energy that cause oxidation of the tissues
[B] The structure of the fat molecules is such that more molecules can fit in lesser space
[C] The fat molecules contain lesser energy and can not be used so easily
[D] None of the above reasons
Show Answer
Correct Answer: B [ The structure of the fat molecules is such that more molecules can fit in lesser space]
Notes:
Trans unsaturated fats are particularly risky because the double bond stereochemistry allows the fat molecules to assume a linear conformation, which leads to efficient packing (i.e., plaque formation).
