Natural selection is the process that result in the adaptation of an organism to environment by means of selectively reproducing changes in its genotype, or genetic constitution. It is the a key mechanism of evolution. Charles Darwin popularised the term "natural selection" contrasting it with artificial selection, which is intentional, whereas natural selection is not.
To make it simple, let's have a group of beetle composing of green and some are brown as an example. here, there is a variation in traits. Since the environment could not support continuous population growth, not all species can reproduce to their full potential. Green beetles can easily be eaten by other species like birds compared to brown beetles. The surviving brown beetles will then generate brown offsprings because their trait has a genetic basis. Since more brown beetles survive and becomes more common in the population, the process continues until all individuals will eventually be brown. so basically, if you have variation, differential reproduction, and heredity, you will have evolution by natural selection as an outcome.

This table shows the codons found in messenger RNA (attached). Using this information, what sequence of nucleotides in the templ
Rashid [163]

Answer:

A

Explanation:

The correct answer would be <u>option A</u> - GUA-CAU-ACC

<em>Looking at the table of codons, for the amino acid Val, the first base (which is on the 1st column in the 6th row) is G while the second base (2nd column, 2nd row) is U. The third column can be any of U, C, A, or G (6th column, 4th row). Hence, GUA is plausible</em>

<em>For the amino acid His, the first base is C (1st column, 2nd row), the second is A (4th column, 4th row) while the last could be any of the 4 bases. Hence, CAU is plausible.</em>

<em>For the amino acid Thr, the first base is A (first column, 5th row), the second is C (3rd column, 2nd row) while the 3rth could be any of the 4 nucleotide bases. Hence, ACC is plausible.</em>

Therefore, the correct sequence of nucleotides for Val-His_Thr would be GUA-CAU-ACC

Ash from the fire helps restore nutrients

Fires clear out the brush along the ground level before they reach the trees, hence clearing the way to prevent larger fires

Eucalyptus and pine only feed after a fire event when the soil is rich

Therefore the odd one out is C
