Use equation 1 from the section to calculate the PCV in each centrifuge tube from the blood sample your group was assigned to test . Record each PCV in the data table below
The packed cell volume is checked in cases where there are symptoms of anemia or erythrocytosis.
The PCV which is also known as packed cell volume is equal to the volume of packed red blood cells which is divided by the total volume of the given blood sample.
GIVEN - Red blood cell volumes are -
5.5 , 5.0 , 5.0 , 5.0 , 4.0
Total blood mixture volume is -
10.0, 10.5 , 10.0 , 10.5 , 9.5
SOLUTION - To calculate the packed cell volume -
5.5 / 10.0 = 0.55
5.0 / 10.5 = 0.47
5.0 / 10.0 = 0.5
5.0 / 10.5 = 0.47
4.0 / 9.5 = 0.42
The main function of packed cell volume is to calculate the red blood cell mass because any increase in the red blood cell mass will be equal to erythrocytosis which means the count of red blood cells is more than the specific sex normal range which is because of plasma volume reduction and also if it decreases then it will lead to anemia because it will have lesser number of red blood cell count and for determining anemia or erythrocytosis the blood test is advised and the reason behind this is cell destruction, blood loss, or failure of bone marrow production and the other name for packed cell volume is hematocrit or volume of packed red cells or erythrocyte volume fraction.

What is population?The number of times a repeated event occurs in a given amount of time is known as its frequency. It is also sometimes called "temporal frequency" to stress the contrast to "spatial frequency" and "ordinary frequency" to underline the contrast to "angular frequency." Hertz (Hz), which is equal to one (event) per second, are the units used to express frequency. The reciprocal of frequency, the period is the length of time occupied by one cycle in a repeating event.
The period, T—the space between beats—of a heart beating at a frequency of 120 beats per minute (2 hertz), for instance, is half a second (60 seconds divided by 120 beats). Science and engineering employ frequency as a key characteristic to define the temporal scale.

Enzymes are proteins capable of recognizing and binding to very specific small molecules, such as glucose. Which level of protein structure most directly leads to this binding specificity?.
Enzymes are proteins capable of recognizing and binding to very specific small molecules, such as glucose. The tertiary structure of protein leads to this binding specificity. The correct answer is option(c).
The three-dimensional structure of proteins is a result of the tertiary structure of the protein. The outer functional groups of a protein are visible on the exterior because of the protein's three-dimensional structure. An interaction between a protein and other molecules is made possible by these functional groups.
Proteins can acquire a very specialized structure because of the tertiary structure. The precise region of a protein called an enzyme known as the "active site" where a specific molecule can fit is known as an enzyme. The active site is in charge of binding particular molecules that can only fit into a particularly active site.

If you mix 172 grams in water and bring it to a final volume of 1,078 ml, what will be the concentration of the resulting solution in g/l? answers cannot contain more than one decimal place.
159.6g/l is the concentration of the resulting solution in g/l
Mass = 172 grams
Final volume = 1,078 ml (convert this to litre)
1000 ml = 1 l
1,078 ml = 1.078l
Initial concentration in g/ml = 172g / 1078ml
Since concentration is given as;
C = n*V
Where c = concentration (g/l)
n = number of moles (grams)
v = volume (litres)
Thus, if 172g is dissolved in 1078 ml
Xg would be dissolved in 1000 ml
By cross multiplication,
1078 * Xg = 172 * 1000
Xg = 172,000/ 1078
Xg = 159.56 g/l

1. The cell membrane plays an essential role in the life of the cell. How does the cell membrane help maintain the health of the
cell?
The cell membrane can govern the processes of waste removal and bringing in necessary supplies by regulating what enters and leaves the cell.
Cells produce the waste molecule carbon dioxide during the process of cellular respiration. Due to the high concentration of carbon dioxide within the cell, it diffuses out of the cell and into the bloodstream (lower concentration). Carbon dioxide is transported by the blood to the lungs, where it can enter the air sacs and be expelled.
The cells require additional ingredients. Glucose is required by cells to supply energy. Through channel proteins in the membrane, glucose can pass from the bloodstream, where it is more concentrated, into cells, where it is less concentrated. This process is called facilitated diffusion.
