Humans put fertilizer on the crops for growth
Explanation:
The answer is reproductive isolation. This ensures that there is no viable reproduction between
different species or subspecies. Even if reproduction
between species leads to conception, the embryo may not be able to survive to maturity or will be sterile. This ensures that
species remain integral by restricting gene flow.
<h3><u>Answer and explanation;</u></h3>
- DNA is a double stranded molecule. Covalent and hydrogen bonds pray important roles in the functioning of DNA molecules.
- <em><u>Covalent bonds occur within each linear strand and strongly bond the nucleotide bases, sugars, and phosphate groups occurring both within each component and between components.</u></em>
- <em><u> Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.</u></em>
- Hydrogen bonds helps the complementary base pairs in DNA; guanine with cytosine and adenine with thymine to connect to one another. The hydrogen bonds between these complementary pairs helps keep the two strands of DNA helix together.
