How is atmospheric nitrogen converted into a biologically useful form of nitrogen?

Biology
1 answer:
frutty [35]3 years ago
8 0

Answer:

The atmosphere is the largest reservoir of the nitrogen as it is composed of 78% of Nitrogen. Although 78%, this is not used by the organisms directly as the nitrogen molecule exists in nature in the form of divalent joined via triple bonds.

These triple bonds require a great amount of energy to be broken and used. Only a few prokaryotic organisms called nitrogen-fixing bacteria have the capability to break these triple bonds as they contain enzymes-nitrogenase complex which converts the atmospheric nitrogen to usable forms like ammonia, nitrates and nitrites. About 92% of the atmospheric nitrogen is fixed through this way rest through thunderstorms and Haber's process.

Thus, nitrogen-fixing bacteria is the answer.

During recombination ________________________.
Sonbull [250]

Answer:

2)chiasmata hold chromosomes together.

Explanation:

Chiasma (pl. Chiasmata): it is the point of contact, the physical union between two non-sister chromatids that belong to homologous chromosomes. In a given chiasma, an exchange of genetic material can occur between both chromatids.

1) is FALSE becasue recombination occurs between chromatids of homologous chromosomes, NOT between sister chromatids.

3) is FALSE because more than one recombination event can occur in a given pair of homologous chromosomes.

4) is FALSE becasue synaptonemal complex keeps homologous chromosomes together, NOT sister chromatids. Additionally, recombination occurs in prophase 1, long before anaphase 2.

Yakvenalex [24]

Answer: Diffusion and osmosis

Explanation:

Water, like many molecules, wants to be at equilibrium; it wants to have an equal concentration on either side of the membrane. The movement of water across a membrane to reach equilibrium is called osmosis. Water molecules move through the phospholipid molecules in the cell membrane by osmosis.

Osmosis is a process through which the molecules pass through a semipermeable membrane across a concentration gradient. Water molecules pass from high concentration to low concentration.
