Ans.
Codons are three nucleotide sequences present on DNA or RNA that codes for the amino acids or provide stop signal at the time of protein synthesis. Each codon codes for a specific amino acid. The amino acid proline (pro) is coded by CCG, CCT, CCA, and CCC; aspartate (asp) is coded by GAT and GAC; glycine is coded by GGA, GGG, GGT, and GGC; and lysine is coded by AAA and AAG.
Thus, the correct answer is 'option D). CCA-GAC-GGC-AAA.'
Answer:
Option B, Most communities never become completely stable
Explanation:
In an ecological succession, most of the species are unstable and they keep on changing continuously. The succession is primarily of two types –
a) Primary Succession – In this, community of species occur on a new habitat which had been never occupied earlier. Or it can be said that it is entirely a new habitat.
b) Secondary Succession – In this, community of species occur in a habitat where earlier life existed but it was disturbed or damaged by some environmental condition.
Hence , the correct answer is option B
The brain structure which monitors his thirst and the need to drink more
water is Hypothalamus.
<h3>What is the Brain?</h3>
This organ is located in the head region of most organisms and serves as
the center of the nervous system.
It has some tissues in which hypothalamus is among which helps to
regulates body temperature, sleep, and appetite. Body temperature is
regulated by drinking water to prevent dehydration.
