Answer:

B) CFU/mL calculations would not be accurate

Explanation:

In microbiology CFU is the acronym for Colony Forming Unit, which indicates the number of bacteria or fungi capable of multiplying under suitable conditions. In this case, CFU/mL indicates how much bacterial or fungal cells, susceptible to reproduction, exist within 1 mL of a culture solution.

When this solution is used, to make a dilution or other laboratory activity, it is important that it be resuspended, that is, mixed, as the bacteria or fungus cells can accumulate in the bottom or surface of the substance, changing the value of CFU/mL and causing inaccurate dilutions if used. When resuspended, the substance presents the appropriate value of CFU/mL, ensuring that the dilution is accurate and effective.

Ostrovityanka [42]

The law of dominance states that the recessive genes are always masked by the dominant genes.

The genes for brown fur will mask those for white fur.

If there are 160 bunnies then 120 of them have brown fur and 40 have white fur.

Thus, 40 bunnies should be white according to the Punnett square.

dolphi86 [110]

Some substances that were not initially filtered in the glomerulus, but must be eliminated from the blood, become a component of urine through the process of urine formation.

Urine: A liquid excrement consisting of water, salts, and urea, which is made in the kidneys then released through the urethra.

The process of urine formation involves 3 major steps:

  1. Filtration:- Blood enters the afferent arteriole during filtration, flowing into the glomerulus where filterable blood components—such as water and nitrogenous waste—move toward the interior of the glomerulus and nonfilterable blood components—such as cells and serum albumins—exit via the efferent arteriole.
  2. Reabsorption: During this, ions and molecules will be returned to the bloodstream. As the fluid's osmolarity (ion concentration) fluctuates, water and ions are eliminated as it moves through the proximal/distal convoluted tubules, the loop of Henle, and the collecting duct.
  3. The process of secretion involves the removal of various substances from the blood into the collecting duct, including hydrogen ions, creatinine, and medications. Urine, the final result of all these procedures, is essentially a collection of chemicals that have not undergone tubular or glomerular reabsorption.

Answer:

The correct answer is option C. Epstein-Barr virus: virus visible inside red blood cells.

Explanation:

The Epstein-Barr virus is a virus or virions that cause several serious diseases such as Guillain-Barre syndrome and kind of cancers. These viruses can be detected by the making smear of blood in the electron microscope.

The electron microscope shows round capsids that have protein encased genetically material that is loosely enclosed in a membrane. These are transmitted through saliva generally.

Thus, the correct answer is C.
