Answer:
A step that is not part of natural selection is people select which individuals breed and which ones do not.
Explanation:
Natural selection is a process in which favorable or unfavorable environmental conditions determine the evolution of species, producing differences in their genotype over a long period of time.
As its name indicates, it is a natural selection, in which no intervention by people is contemplated, so that <u>people cannot determine which individuals breed</u>.
Natural selection implies that the characteristics on which the environment influences are inheritable, that there is genetic variability in the population and that the variability of these characteristics implies the ease of reproduction and survival capacity.
<em>The other options do form part of natural selection, since they are based on the three premises of this process:
</em>
- <em>Inheritable characteristics.
</em>
- <em>Genetic variability.
</em>
- <em>The variability of characteristics influences reproduction and survival.</em>
<span>Are mirror images of one another
in science, an enantiomer, otherwise called an optical isomer, where you have two stereoisomers that are perfect representations of each other that are non-superimposable , much as one's left and right hands are the same aside from being turned around along one pivot.</span>
It’s D (example a turtle draws its head back into its shell when it’s shell is touched) I’d say it’s kinda of the same as odor (if u already answered it then dang)
If a cytosine base is substituted for by a thymine base in a DNA segment during DNA replication, the sequence could code for the wrong amino acid during translation.
The change in the sequence of DNA is known as mutation.
When a base substitution occurs in the sequence of a DNA during replication, the genetic information in the region where the substitution occurred becomes compromised.
During transcription, the process of encoding genetic information on DNA into RNA, the base substituted is also transcribed along. If cytosine is substituted by thymine, adenine is transcribed instead of guanine.
During the translation of the genetic codes, the wrong amino acids might end up being translated due to the substituted base, leading to a faulty protein.
