There could be a chance of the plants growing faster, but that would also depend on sunlight and water balances. Photosynthesis would be about the same
Answer:
The ability to reproduce on land without needing external water. (Ans. A)
Explanation:
Internal fertilization is defined as the process where, sperm is fertilizing the egg within the female reproductive tract. Internal fertilization helping in to protects the fertilized embryo from harsh environment, predation, and they are able to reproduce on land without any need of external water, which results as higher survival rates.
This fertilization includes 3 main methods for fertilization:
1) Oviparity: In this fertilization eggs are placed outside the female body and nourishment of embryo comes from the yolk which is a part of the egg.
2) Ovoviparity: In this process eggs held within female and nourishment is comes from the yolk.
3) Viviparity: In this process development of embryo occurs within female followed by live birth and nourishment is received directly from the mother with the help of placenta.
In internal fertilization, fertilized eggs are protecting from dehydration on land this is the advantage of this method of fertilization.
Answer:
Once a star has reached the main-sequence stage of its life, it derives its energy almost entirely from the conversion of hydrogen to helium via the process of nuclear fusion in its core
Adaptive genes are selected and passed from generation to generation.
<h3>Natural selection and the evolution of long necks in giraffes</h3>
According to Darwin's theory of natural selection, natural selection selects for adaptive genes in organisms and deselects non-adaptive genes.
Thus, adaptive genes are passed from generation to generation.
In the case of the giraffes. It is plausible that their ancestors kept on stretching their necks in order to feed as the trees they fed on kept growing taller. The taller the tree grows, the longer the ancestors of giraffes stretched their necks to reach it. Otherwise, they just might have to die of starvation.
This adaptation activated the long-neck genes in the ancestors of giraffes. Natural selection selects this trait and it was passed down across generations.
