Answer:
Step 1: Pollination
In general, male gametes are contained in pollen, which is carried by wind, water, or wildlife (both insects and animals) to reach female gametes. The pollen is deposited on a plant's stigma, which is part of the pistil (the elongated part of a flower extending from the ovary). This process is called pollination.
Step 2: Germination
Within a few minutes, pollen tubes begin growing, or germinating, toward the egg cell. These tubes will provide a path for the sperm carried in the pollen to reach the egg.
Step 3: Penetration of the Ovule
The pollen tubes penetrate the ovule, which contains the female gametes.
Step 4: Fertilization
Sperm travel down the pollen tubes and fertilize an egg. Most angiosperms undergo double fertilization, where both an egg and the polar nuclei in the embryonic sac are fertilized.

The sorting of genes during sexual reproduction results in a large amount of genetic variation.because the primary advantage sexual reproduction has against asexual reproduction because of genetic diversity
B is the right option

Answer:
eing ecids combine to form nucleic acids
Explanation:
I truly don't know
I'd mark answer B :) technically it means that you must eat enough food rich in those aminoacids because they can't be synthesized by the organism.
