<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.
The scientists' conclusions are most likely unreliable because <u>he asked the wrong set of people for his survey.</u> By definition, environmentalists are those people who are inclined to believing that humans are entirely responsible for creating biological foot prints all over the Earth. They always advocate the protection of the environment and even persuade people to follow suit. It is natural for them to react in such a manner that they find dams as something harmful because to them, dams destroy the natural cycle of Mother Earth.
You should draw d.eez nuts XD
Hello,
<span>Winds are caused by air moving around in the atmosphere. Wind turbines harness the mechanical energy in wind and convert it into electricity. Solar energy is the source of the mechanical energy in wind.
