Assume that a 100 cm3 soil core weighs 78g when oven-dried and 123 g when saturated. Calculate the total pore space and total porosity. Show all of you work.

Answers

Answer 1

To calculate the total pore space, we will find the difference between the mass of the soil when it is oven - dried and when it is saturated. Therefore, the value of the total pore space and total porosity are 45g and 45% respectively

Given that a 100 cm3 soil core weighs 78g when oven-dried and 123 g when saturated.

The given parameters are;

Volume of soil V = 100[tex]cm^{3}[/tex]

Mass ( Oven dried) [tex]M_{1}[/tex] = 78g

Mass ( Saturated) [tex]M_{2}[/tex] = 123g

In the soil formation, pore space refers to the volume of soil. And to calculate the total pore space, we will find the difference between the mass of the soil when it is oven - dried and when it is saturated. That is,

Total pore space =  [tex]M_{2}[/tex] - [tex]M_{1}[/tex]

Total pore space = 123 - 78

Total pore space = 45g

And total porosity will be the percentage of the ratio of total pore space to the given volume of the soil. That is,

Total porosity = (Total pore space / volume of the soil) x 100

Total porosity = 45/100 x 100

Total porosity = 0.45 x 100

Total porosity = 45%

Therefore, the value of the total pore space and total porosity are 45g and 45% respectively

Hereditary spherocytosis (HS) is a disorder of red blood cells that causes the cells to be smaller and spherical instead of having the usual flattened, biconcave shape. The average diameter of normal red blood cells is 7.2μm, and the average diameter of red blood cells in a person with HS was found to be 6.7μm. The normal red blood cell has an average surface area of 136μm2 and an average volume of 91μm3.

Which of the following provides an accurate calculation of the surface area to volume ratio of an HS red blood cell, as well as a prediction of its effect on the efficient transferring of oxygen compared to a normal red blood cell?

Answers

The statement that provides an accurate calculation of the surface area to volume ratio of an HS red blood cell is The ratio is 0.89, and the cells are less efficient at transferring oxygen.

The ratio 0.89 is less than the ratio that is seen in a normal red blood cell, therefore, the cell would be less organized at moving oxygen.

Hereditary spherocytosis (HS) is often referred to as a disease that can be inherited. It is known to affects the red blood cells.

Its symptoms includes the killing of red blood cells in the spleen and their removal from the blood stream amidst others.

Using the principle of binomial probability, the probability that more than 3 friends win a prize is

Recall :

P(x = x) = nCx * p^x * q^(n-x)

Given the Parameters :

Probability of success, p = 1/6 q = 1 - p = 5/6 Number of trials, n = 7x3

Hence,

P(x ≥ 3) = p(x = 3) + p(x = 4) + p(x = 5) + p(x = 6) + p(x = 7)

P(x ≥ 3) = 0.0781 + 0.0156 + 0.0019 + 0.0001 + 0.000003

what type of cell signaling is clonal selection?

Answers

The clonal selection theory proposes that antigen selects lymphocytes for activation from a population of cells precommitted to produce specific antibody. Implicit in this theory is that antibody-forming cells are monospecific and express cell-surface receptors capable of binding foreign antigens.

Interaction of antigen with these side chains induced the cell to synthesize additional antibody molecules. This proposal seemed untenable once Karl Landsteiner demonstrated that the immune system could produce antibodies to a vast array of antigens; for over 50 years theories of antibody formation postulated that antigen instructed cells to synthesize antibodies complementary to the antigen. The introduction of the clonal selection theory of antibody formation by Macfarlane Burnet in the 1950s revived the idea that antibody-forming cells express cell-surface receptors by which they bind antigen. In 1961, Göran Möller provided the first evidence that antibody-forming cells had antibody (immunoglobulin) on their surface. The antigenbinding specificity of these immunoglobulin molecules was shown to be identical to the antibody that cells will produce when activated. Initially, many immunologists thought that the T lymphocyte receptor would also be an immunoglobulin molecule. However, studies by several laboratories in the early 1980s using a combination of monoclonal antibodies and molecular genetic techniques showed that the receptor consists of two polypeptide chains. The antigen-specific receptors on both T and B lymphocytes are associated with other trans-membrane molecules involved in the transduction of activation signals into the cell.
