Answer: The correct answer is- A.Gene Pool.
Gene pool can be described as the collection /set of all the genes that are present withing a particular population of interbreeding individuals.
In other words, it includes all the variants of a gene (also called allele, such as dominant and recessive allele) present in a population. Gene pool is generally related to a population of around a specific species.
Thus, option A) is the right answer.

Answer:
The most radioactive purified biological molecule will be RNA
Explanation:
RNA (ribonucleic acid) like DNA, is a long, unbranched macromolecule consisting of nucleotides joined by 3' - 5' phosphodiester bond.
In the cultured yeast, RNA is the most radioactive purified biological molecule because RNA is normally single stranded and does not undergo mutation, replication nor transcription.
Hence, it conserves the ultraviolet light absorbed from the radioactive phosphate during the culturing of yeast
Answer: It increases the amount of solar radiation that is reflected into space. It increases the amount of solar radiation that is absorbed by oceans and lakes
(hope it helps)
Explanation:
This statement is true. Only active transport can move molecules up a concentration gradient using energy. Passive transport on the other hand, uses no energy and occurs naturally. Therefore molecules can only move a concentration gradient.
