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.

If a cell is placed in an isotonic medium, there will be no net movement of water. True or false?.
ASHA 777 [7]

It is true.

<h3>What is isotonic medium?</h3>
  • A solution that has the same amount of salt as cells and blood. In hospitalized patients, isotonic solutions are routinely utilized as intravenous fluids.
  • When a cell is immersed in an isotonic solution, there is no net movement of water into or out of the cell, and the volume of the cell remains constant.
  • Isotonic solutions include 0.9% normal saline and lactated ringers. A hypertonic solution is one that has a greater solute concentration than the solution across the semi-permeable barrier.
  • The isotonic solution allows the cells to move water and nutrients in and out of the cells. This is necessary for the blood cells to perform their function of supplying oxygen and other nutrients to other parts of the body.

6. How might a disturbance in a food web impact other organisms in the marine<br> environment?
Viefleur [7K]

What is the climate and weather information of freshwater wetlands
ziro4ka [17]

Answer:

The average temperature of a freshwater wetland in summer is 76 degrees Fahrenheit. The average temperature in winter is 30 degrees Fahrenheit. The climate in freshwater wetlands is usually semitropical, as freezing conditions rarely occur.

Explanation:

The most common freshwater wetland is swampland. The freshwater biome is located on every continent except for Antarctica. Most people think of it being a nuisance, but freshwater wetlands are an important part of our ecosystem. More examples of freshwater wetlands are marshes or bogs. In freshwater wetland the water will always be standing water. Most of them will have water in them all of the time, but some will only have water in them during certain parts of the year. There are 4 different seasons in freshwater wetlands. There is Summer, Fall, Winter, and Spring. The average temperature of a freshwater wetland in summer is 76 degrees Fahrenheit. The average temperature in winter is 30 degrees Fahrenheit. The average rainfall in a freshwater wetland is 59 inches or 150 centimeters to 200 inches or 500 centimeters. The freshwater wetlands get and average of 7-10 hours of sunlight a day throughout the year.
