Answer:
The microorganisms present metabolic wastes that serve as the primary source of food for other living things.
Bacteria that live free in the soil or in symbiosis with plants are essential to fix nitrogen, both nitrates and ammonia. These bacteria take nitrogen directly from the air, originating compounds that can be incorporated into the composition of the soil or living beings.
This property is restricted only to prokaryotes and is widely distributed among different groups of bacteria and some archaeobacteria. It is a process that consumes a lot of energy that occurs with the mediation of the enzyme nitrogenase, which the rest of the living organisms that cannot do or comply with this process is because they lack said enzyme.
Dunaliella is a genus of microscopic algae of the Chlorophyceae class and of the order Volvocales. All are unicellular, although with very varied morphologies.
Morphologically, its main characteristic is that they lack a rigid polysaccharide cell wall.
The ecology of this genus of green algae is characterized by its high tolerance to salinity, with eukaryotic organisms having greater tolerance to salt. They are euryhaline, adapted to salt concentrations from 50 mM NaCl to almost 5.5 M NaCl.
Explanation:
By nitrogen fixation is meant the combination of molecular nitrogen or dinitrogen with oxygen or hydrogen to give oxides or ammonia that can be incorporated into the biosphere. Molecular nitrogen, which is the majority component of the atmosphere, is inert and not directly usable by most living things. Nitrogen fixation can occur abiotic (without the intervention of living beings) or by the action of microorganisms (biological nitrogen fixation). Fixation in general involves the incorporation into the biosphere of a significant amount of nitrogen, which globally can reach about 250 million tons per year, of which 150 correspond to biological fixation.
No because sugar is transported into the cell by active transport.
Answer:
Trunk flexor endurance test.
Explanation:
McGill’s torso muscular test is generally used to assess the muscle endurance of the torso muscles that works as a stabilizer. This test generally includes the four major test.
The test that includes the trunk flexor of the endurance test is a timed test that involves the static isometric contraction of the muscles. This test stabilizes the spine til the individual cannot hold the assumed position and the individual exhibits the fatigue.
Thus, the correct answer is option (A).
Answer:
Last electron level
Explanation:
Valance electrons are always in the outside level!

The answer to this question would be: Inhibited grief.
Inhibited grief happens when someone <span>does not display any sign of mourning. This kind of grief can cause a health problem like a stomach ache or a headache. It is important to resolve the grief when losing someone important so that grief doesn't come back as an unexplained medical problem.</span>
