<span>The outer hair cells respond to sound by slightly tilting and changing length. because of the consequence of this, the action of the outer hair cells is called the cochlear amplifier. 

This activity of outer hair cells can amplify the vibration so it's called cochlear amplifier. A disturbance in this mechanism can cause hearing loss.</span>

If 32 packed volume units of cells are separated from 46 volume units of plasma from a blood sample, the haematocrit is _______
nordsb [41]

Answer:

If 32 packed volume units of cells are separated from 46 volume units of plasma from a blood sample, the hematocrit is <u>41,02%</u> percent. The hematocrit value is <u>within the normal</u> range.

Explanation:

Hello!

Hematocrit (or packed cell volume -PCV-)is defined as the percentage of red blood cells (vol%) in a blood sample. One common method of determining it is by centrifuging a heparinized blood sample in a capillary tube at 10 000 RPM for five minutes. This separates the blood sample in two layers, formed elements (RBC and WBC) and Plasma.

The length of the layers is directly measured from the tube and represents the volume of packed cells and plasma. Since the number of white cells is negligible compared to the number of red cells, the formed elements are considered to represent the red blood cells.

The hematocrit can be calculated as the volume of packed cells divided by the total volume of the blood sample.

\frac{PCV}{TOTAL(pcv+plasma} * 100

<u>In the question:</u>

\frac{32}{32+46} * 100 = \frac{32}{78} * 100 = 41,02%

In humans the normal hematocrit range is 40,7% to 50,3% for men and 36,1% to 44,3%. Taking these reference values into consideration, this sample is within the normal range.

I hope you have a SUPER day!

Other than the modern horse, what was important of the evolution of an organism?
Marat540 [252]

Answer:

Evolution is considered a way in which past generations were able to adapt to the difficulties and changes that the world around them imposed, from the need to seek food to survival in the face of different climatic and landscape changes, becoming stronger and therefore allowing the enduring and transcendence of it.

Explanation:

The importance of evolutionary studies is very large, since all organisms and their characteristics are products of evolution. It has an enormous interest applied in topics such as biodiversity conservation, medicine, agriculture, livestock, etc. Evolutionary biology is concerned with understanding the processes that have given rise to the current characteristics of organisms, and explaining why the characteristics of those organisms are what they are and not different ones.
