marishachu [46]

Answer:

66 * 10^8 CFU/mL

Explanation:

Given -

a) Number of colonies of bacteria is equal to 66

b) Total volume of the solution is equal to 0.1 mL

c) Dilution factor is equal to 10^{-7}

As we know that

CFU/mL = \frac{N * DF}{V}

Where N is the number of bacterial colonies, DF is the dilution factor and V is the volume

Substituting the given values in above equation, we get -

CFU/mL = \frac{66* 10^7}{0.1} \\= 66*10^8

inn [45]

Answer:

The correct answer is option b, that is, inhibition of vasopressin.

Explanation:

Vasopressin also called ADH or anti-diuretic hormone results in the resorption of water by the collecting duct and the distal convoluted tubule of the nephron, and thus, minimizes the reduction of water via urine. Consuming ethyl alcohol results in the prevention of the secretion of ADH that results in frequent urination.

Carbohydrate residues attached to the membrane lipids are always positioned on the extracellular side of the membrane

Carbohydrates are significant parts of the cell membrane, present just on the external surface of the plasma layer, and are appended to proteins, framing glycoproteins, or lipids, and framing glycolipids. These carbohydrate chains might comprise 2-60 monosaccharide units and can be either straight or branched.

The carbohydrates of the membrane are engaged with cell bond and acknowledgment and go about as a physical barrier. Enormous, uncharged particles, for example, glucose can't diffuse through the membrane.

These carbohydrates structure particular cell markers, that permit cells to perceive one another. These markers are vital in the resistant framework, permitting safe cells to separate between body cells, which they shouldn't assault, and unfamiliar cells or tissues, which they ought to.

Which of the following statements is INCORRECT about how the components of hemoglobin are recycled?
Over [174]

Answer:

C

Explanation:

The globin of the RBC is broken down into constituent amino acids that can be reutilized by the phagocytic cells (this can occur in the spleen, liver and lymph node). The chains cannot be reused in their large form. The heme(iron) is transported by the blood to the bone marrow and is used to make new red blood cells.
