Answer:
D. Genetic material (DNA/RNA)
Answer:
• Nitrogen cycle shows how nitrogen is cycled in the environment whereas carbon cycle shows the cycling of carbon. • The reservoir for nitrogen cycle is atmospheric nitrogen whereas for carbon it is carbon dioxide gas. • Nitrogen reservoir is much larger compared to carbon reservoir.

Answer:
The strands of the hybrid helix are less complementary than the original helix.
Explanation:
Complementary DNA strands are bonded to each other through hydrogen bonding. The nitrogenous base adenine (A) forms 2 hydrogen bonds with thymine (T). Guanine forms 3 hydrogen bonds with cytosine. Due to the presence of 3 hydrogen bonds, GC rich regions of DNA or RNA are more strongly bonded.
Therefore, if the two strands will be less complementary or contain more AT rich regions, the double helix will denature or melt at a lower temperature.
Answer:
building proteins storing energy providing structure to cell walls carrying genetic information building proteins. storing energy. providing structure to cell walls.
Answer:
Change the number of neutrons in an atom and it becomes an isotope, change the number of electrons, it becomes an ion. When you change the number of protons in an atom, you will change the atom from one element to a different element. Sometimes, when you add a proton to an element, the element will become radioactive.
Hope this helps!
