Answer:

Formation of oxygen and abiotic molecules.

Explanation:

The present day organisms use oxygen for process of respiration. There are very few organisms which require source other than oxygen. The first organisms which make oxygen from photosynthesis were cyanobacteria.

The formation of abiotic molecules like nucleotides and amino acids were responsible for origin of life. These molecules arranged together, thus forming large molecules like nucleic acid and proteins.

Photosynthesis, respiration, volcanic eruption, decomposition
SVETLANKA909090 [29]

Answer:

-> photosynthesis: the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

-> respiration: a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.

-> volcanic eruption: Volcanic eruptions happen when lava and gas are discharged from a volcanic. Volcanic eruptions often cause temporary food shortages and volcanic ash landslides called Lahar. The most dangerous type of volcanic eruption is referred to as a 'glowing avalanche'.

-> decomposition: Dead organisms are broken down into smaller pieces by the process of decay.

Explanation:

Hope you get your answer correct!

Have a good day :D

What Major adaptations necessary for survival are in the temperate rain forest
Ahat [919]
Some plants also have large leaves to soak up nutrients and water, very helpful in this biome since it rains a lot. - Having some needles cased in wax, withstand cold temperatures and losing water from their leaves. - Having thin bark and shallow roots enables trees to withstand fire.

How do the kidneys work to neutralize metabolic acidosis or alkalosis? If metabolic alkalosis exists, the kidneys slow their aci
melomori [17]

Answer:

Attaching letters to the options to make the question readable:

A. If metabolic alkalosis exists, the kidneys slow their acid excretion.

B. If metabolic alkalosis exists, the kidneys slow their acid retention.

C.  If metabolic acidosis exists, the kidneys slow their acid excretion.

D. If metabolic acidosis exists, the kidneys increase their acid retention

The correct answer to the question above is option A (If metabolic alkalosis exists, the kidneys slow their acid excretion.)

Explanation:

Metabolic acidosis is a condition where there is an alteration in the acid-base balance in the blood. Here, as the name implies, a high level of acid than necessary are found in the blood as a product of metabolism caused by an increase in acid production, failure of acid to be expelled in the kidney.  

Metabolic alkalosis is a condition where there is high level of alkaline in the blood than the body requires. Metabolic alkalosis occurs when the kidney is unable to excrete excessive alkaline in the blood and when there is too few acid-producing hydrogen ions present.

Kidneys fight metabolic acidosis by balancing acid levels in the blood by removing excessive acid in the blood through urine. It is also possible for the body to expel volatile acids through the lungs in the form of exhaled air.

Ways kidneys work to neutralize metabolic acidosis, ls If metabolic acidosis exists, the kidneys increase their acid excretion.

Ways kidneys work to neutralize metabolic alkalosis, is If metabolic alkalosis exists, the kidneys slow their acid excretion and increase their alkaline excretion or slow their alkaline retention.

Please answer right! thanks ​
cestrela7 [59]

Answer:

It develops over land and is cold and dry!

Explanation:

It's a continental air mass, so it develops over land! Maritime ones develop over water. It's cold and dry because it's a polar air mass, not tropical!

I hope that helped you!
