Answer:
The correct answers are options A, C and D.
Explanation:
As sexual reproduction enhances the genetic diversity, thus, the procedure entirely enhances the fitness of the population. The sexual females are only half as associated with their offspring in comparison to the asexual females. This is known as the cost of meiosis, this signifies that there is a dramatic decline in the relatedness in the generation of the out-crossed sexual offspring.
According to the Red Queen hypothesis, parasitism encourages sexual reproduction in the host and an evolutionary trade-off between virulence and transmission.
Answer:
The carbon cycle describes the storage and exchange of carbon between the Earth's biosphere (living matter), atmosphere (air), hydrosphere (water), and geosphere (earth). The main reservoirs of carbon are the atmosphere, biosphere, ocean, sediments, and interior of the Earth. Both natural and human activities transfer carbon between the reservoirs.
Explanation:
<u>Answer: -</u><u> </u>Magma chamber.
<u>Explanation</u>:-
1. A magma chamber is a cavity which acts a reservoir of magma and it feeds a volcano.
2.A <em>magma</em> is basically a mixture of molten and semi molten rocks.
3. The magma is less dense than the layers of rocks and as a result of this it tends to move upwards towards the surface of the earth but when it encounters a layer of rocks in this upward journey that hinders its movement then it gets collected in a large pool which is known as the <em>magma chamber</em>.
4. These magma chambers are under a great pressure which results in the breaking of the rock which surrounds the magma chamber with time. Once, these rocks break the magma can then travel upwards and this results in volcanic eruption.
<em>Thus, these magma chambers are the cavities containing the magma that feeds the volcano.</em>
