How is a recessive allele different from a dominant allele apex?

For the trait that is coded by a recessive allele to be expressed, the must be homology, which means that an offspring has to inherit that recessive allele from both its parents.

A dominant allele will dominate over the recessive allele, so for the trait coded by a dominant allele to be expressed, the offspring only needs to inherit the allele from one of its parents.

For example: "R" is brown eyes, "r" is blue eyes.
Now you get one R from each of your parents.
RR (homozygote) = brown eyes
Rr (heterozygote) = brown eyes
rr (homozygote) = blue eyes

a The nature of A and D is their ionic properties and as a result of their iron content.

d. The reagent is acetone alcohol, because it causes shrinkage of the peptidoglycan layer.

<h3>What is differential staining?</h3>

Differential staining is a staining process which involves the use of more than one chemical stain.

The use of multiple stains allows for better differentiation between different microorganisms or structures/cellular components of a single organism.

a. The nature of A and D might be their ionic properties and this could be as a result of high content of Iron.

b. Reagents in gram staining represent differential stains used for the microscopic examination of bacterial cultures and laboratory specimens.

c. The appearance of gram positive is purple and gram negative is pink

Gram positives take the color of the primary stain during gram staining which is crystal violet- purple

Gram positive take the color of the secondary stain which is safranin- pink

d. The colorless reagent which is the acetone alcohol should not exceed the recommended time because it would dehydrate and shrink the peptidoglycan layer of the bacteria leading to a false result.

Arturiano [62]

The correct answer is: MAO inhibitors.

MAOI - monoamine oxidase inhibitors are antidepressants that affect the enzyme called monoamine oxidase which normally removes the neurotransmitters norepinephrine, serotonin and dopamine from the brain. As a consequence, neurotransmitter’s activity is increased. MAOIs interact with tyramine, amino acid found in food such as cheese, smoked sausage, and red wine. Tyramin eis normally regulated via MAO. So, when the MAO is inhibited via MAOI, tyramine reaches high levels, causing the blood vessels to narrow and resulting in critically high blood pressure.
