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.

By controlling what enters and leaves a cell, the cell membrane A) aids in maintaining homeostasis within the cell. Homeostasis is the process by which organisms maintain life through eating, growing, and living in variable conditions. It would not make sense to answer B) because organisms do not control the homeostasis of their external environment. D) also would not be correct because cell's do not control osmosis in the external environment. The membrane does not control osmosis because osmosis is generally a random process of molecular diffusion whereas the membrane acts in a conscious and controlled way.
Answer:
B. decreased its genetic diversity
Explanation:
if the number of chances the white flower decreases, and there are more purple chances, then there is less genetic diversity.
B. Sympatric evolution. is responsible to this. It's the process of evolving species from one shared ancestor in the same geographic region.
a - fossil fuels
step by step explanation:
fossil fuels are non-renewable and will run out
