Beyond their role in energy transfer, what other benefit do microorganisms that act as producers provide for ecosystems?
insens350 [35]

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.

Diana jones is 5'4" and weighs 145 pounds. would the anesthetic choices be the same for diana as they would be for a 6'3" 210 lb
ankoles [38]

Answer:

Propofol (another name Diprivan) can be used for Diana's surgery. It is a sedative or anesthesia commonly used for children and adults. Studies show that there were no significant differences in dose requirements based on sex or age, except for the too elderly.  The difference in dosing considering different body weights were not statistically significant also.  The same dose is safe

( 0.1-0.15 mg/kg/min IV for 3-5 min) for Diana, the 210 lb man or a 10-year-old girl. However, the dose was higher in patients with bradycardia and hypotension.
