Answer:
Option-A
Explanation:
In the given question, the person predicts that if CO₂ level in the atmosphere will be increased then the phytoplanktons will grow more and the atmospheric carbon will be absorbed and will be fixed.
This statement juts seem like assumptions and if we consider this as a hypothesis then the facts will not be in favour of this hypothesis.
In the present day, the CO₂ level has already increased but the plants are not been able to utilise the Carbon dioxide and reduce global warming as the carbon uses free carbon from the atmosphere only and not bound carbon.
Thus, Option-A is correct.
Picture B
That is when the cell start to become two identical daughter cells
Well, the asthenosphere is located in the upper mantle. So that is how they are related.
The greatest degree of genetic variation would be found in an offspring resulting from sexual reproduction.
<u>Explanation:</u>
Asexual reproduction produces very less variations. Asexual reproduction requires only one parent and thus the offspring would be very similar to the parent. The chance of variations in offspring is very less.
But the case of sexual reproduction is different. Sexual reproduction involved two parents and each parent contribute equal amount of genetic material to the progeny.
Some characters of the offspring will be like one or the other parent and some characters will be a combination of the characters of both parents
. Such a combination produces variant offspring.
