The most important factor that determines the percent of oxygen saturation of hemoglobin is
erik [133]

Answer:

This question lacks options, options are:

a) The partial pressure of oxygen

b) Acidity

c) The partial pressure of carbon dioxide

d) Temperature

e) BPG

The correct answer is a. The most important factor that determines the percent of oxygen saturation of hemoglobin is <u>The partial pressure of oxygen </u>.

Explanation:

Hemoglobin is an oxygen transport protein. Partial Oxygen Pressure (PaO2), measures the pressure of dissolved oxygen in the blood, that is, it shows how well oxygen passes from the lungs into the bloodstream. A high partial pressure of oxygen in the blood produces an almost complete saturation of hemoglobin, which indicates the maximum amount of oxygen that combines, but when PaO2 is reduced, so is hemoglobin saturation, when saturation is below 90% hypoxemia occurs, that is, the level below normal blood oxygen levels.

Outline the process of the Carbon Cycle.
Bond [772]

Answer:

Carbon Cycle Definition

Carbon cycle is the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.

Carbon Cycle Steps

Following are the major steps involved in the process of the carbon cycle:

Carbon present in the atmosphere is absorbed by plants for photosynthesis.

These plants are then consumed by animals and carbon gets bioaccumulated into their bodies.

These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.

Some of the carbon that is not released back into the atmosphere eventually become fossil fuels.

These fossil fuels are then used for man-made activities, which pumps more carbon back into the atmosphere.

Hope it helps!!!

Use the drop-down menus to complete the statements. <br><br> Meiosis involves cell divisions.
denpristay [2]

Answer:

Meiosis involves two cell divisions

Explanation:

Mitosis and meiosis are two kinds of cell divisions and one of the main differences between the two is that meiosis goes through <u>2 nuclear divisions</u>.

Meiosis has Meiosis I and Meiosis II division. In Meiosis I, the number of chromosomes in the daughter cells are only half of the parent cells. This is why it is called a reduction division, because the chromosomes will be reduced by half. In Meiosis II, the daughter cells will have the same number of chromosomes as the parent cells, which in this case is the daughter cells of meiosis I.
