5 0

Answer:

The answer is a  Hematocrit measure the time for erytrhocytes to settle to the bottom of the upright tube at room temperature.

Explanation:

Hematocrit is the measurement of  percentage of red blood cells or RBC  in a given blood sample.The normal RBC percentage  in blood  of male is 40 percent to 50 percent and in case of female blood is 36 percent -44 percent .

                  The measurement of RBC of a blood sample is very much important because RBC performs the main function of blood that is to transport oxygen and carbon di oxide to and from the body.

                         Hematocrit is done to test anemia(decreased percentage of RBC) and Polycythemia(increased percentage of red blood cells ).

Think about the carbon cycle. Describe how each of the two systems in your experiment modeled
amm1812

To identify how your experiment represents the carbon cycle analyze how each Earth's sphere participates in the cycle and relate it to the experiment.

<h3>What is the carbon cycle?</h3>

This is a natural phenomenon on Earth in which carbon circulates through different spheres.

<h3>What is the role of each sphere?</h3>
  • Atmosphere: Contains gaseous carbon as carbon dioxide.
  • Biosphere: Plants use carbon and release oxygen; on the other hand, animals produce carbon as a result of the breathing process.
  • Geosphere: Contains carbon, which is the result of processes such as organisms' decay.
  • Hydrosphere: Contains dissolved carbon.

<h3>How do you relate the experiment to the natural process?</h3>
  • Identify the components of your experiment and the way they interact with carbon.
  • Compare this function to the function of the speheres.
  • Relate the experiment and natural model.

Note: This question is incomplete because there is not information about the experiment; due to this, the answer is based on general knowledge.

The following options are all reproductive barriers. Which one is an example of a prezygotic barrier in which the two different
12345 [234]

The correct option is this: TWO DRAGONFLY SPECIES REGULARLY MATE BUT THEIR GAMETES ARE INCOMPATIBLE.

In biology, there are different types of reproductive barriers, one of these is prezygotic barrier. A prezygotic barrier is a kind of mechanism that prevent reproduction from occurring by blocking fertilization. In this case, the concerned species will be mating together, but their gametes will not be compatible and thus, zygote will not be formed.

A postzygotic barrier on the other hand is said to occur when the reproduction process is blocked after the formation of zygote or after fertilization has taken place. A good example of this is an hybrid mule that is sterile and can not reproduce.
