Hi, the given question is incomplete, it is missing a diagram, the diagram is given in the attachment below,

Answer:

The correct answer is adaptive evolution.

Explanation:

Based on the given information, it is clear that it best illustrates the phenomenon of adaptive evolution. It is known that different species of finches exhibit an ancestor, which is common, however, all the species have shown adaptation based on the kind of food they are getting within their surroundings.  

The evolutionary modifications that arise by getting adaptive to the specific environment are termed as adaptive evolution. These changes arise due to the phenomenon of natural selection, which further enhances the tendency of reproducing or survivorship after going through some of the challenges presented by the surroundings.

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!

Answer:
