The answer is A.
Nucleotide sequences are our genetic messages that allow cells to build proteins (aka polypeptides). When the sequence changes, the genetic code can be altered, and therefore the outcome of protein translation can be changed.
B is wrong because the gene change may not even affect the protein, and even if it does, it may not even have a measurable effect on the organism. And it's unlikely that one gene change will change an animal into a different animal.
C is wrong because there's literally entire fields of genetic biology/microbiology dedicated to this subject.
D is wrong because wtf does it even mean? And yes, change in your genetic code can have impact. It's more or less how cancer happens.
Answer:
C
Explanation:
A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction.
Answer:
The stratosphere
Explanation:
Approximately 90 % of the ozone layer resides in the stratosphere and rest 10 % resides in the troposphere .
<u>Stratosphere -</u>
It is the second major layer of the atmosphere , present exactly above the troposphere layer .
The stratosphere has a layers with warmer and cooler region , the warmer layers are present above the cooler layers .
Explanation:
The Sun warms our planet, and with the Moon, creates the tides. The Moon orbits the Earth and in turn, the Earth orbits the Sun. We see the Universe from a platform that is both rotating on its axis, and traveling in an elliptical orbit around the Sun.
