Answer:

That scrape on our knee will never heal and the blood loss due to bleeding will never be replaced. This is because RNA is inside of cells and without the ability to create new RNA you cannot replace missing cells. So the scrape will never heal if your cells cannot create new RNA.

Explanation:

hope this helps. . . <3

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!

Please find me an information about aerobic and anaerobic organisms​
kaheart [24]

Answer:

An aerobic organism or aerobe is an organism that can survive and grow in an oxygenated environment. In contrast, an anaerobic organism (anaerobe) is any organism that does not require oxygen for growth. Some anaerobes react negatively or even die if oxygen is present.

Division of labour occurs even at cellular level. Explain this statement.
OleMash [197]
Division of labor is essentially when tasks are divided and carried out by specific parts. This occurs in cells, where different tasks are distributed among different parts, referred to as the organelles. For example, the mitochondria in the cell produce energy to carry out cellular activities. The nucleus is involved in cellular division and other genetic functions. In such a manner, the "labor" that a cell has to perform is divided among its organelles.
