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.
<span>The answer is letter B.
Some bacteria that interact with humans can cause benefits to the body when they are small in numbers. An example of this bacteria is the lactobacilli which can be found as an ingredient in some drinks that can purify the digestive system. Though, they can only be taken in small amounts because they may overwhelm the immune system which can cause major complications within the internal organs. Some bacteria that interact with humans can be harmful because of their capacity to divide at a fast rate. <span>

Answer:
The correct answer would be - parents, offspring, and siblings of the suspect.
Explanation:
DNA percent that relatives share with an individual varies according to the type of relationship they share with the individual person. The average DNA percentage that is shared with the close biological family that is parents (mother or father), offspring (son or daughter) or the siblings (brother or sister) is about 50% which is the maximum and best choice for the DNA match for the determining whether the suspect committed crime or not.
Other relatives share only 25 % or less average DNA percentage share with the individual.
Thus, the correct answer is- parents, offspring, and siblings of the suspect
Answer: All living things are comprised of cells are in the case of unicellular organisms a cell. And what determines if something is living is whether are not it can reproduce without the assistance of a host organism. Some organelles all cells contain whether prokaryotic are eukaryotic are cell membranes Genetic material (DNA and forms of RNA) a cytoplasm and ribosomes. Obviously there are many more organelles but these are some shared by all cells whether prokaryotic, eukaryotic or plant a type of eukaryote.
