Answer:

What is a colony-forming unit and how is it used to infer microbial numbers in a sample? A colony-forming unit is the measurable number of colonies that are formed on the agar plate solution. In this experiment, each colony formed of S. cerevisiae will be a colony-forming

Inhibitory neurotransmitters such as glycine and GABA make a postsynaptic cell harder to depolarize by allowing what?
Mashutka [201]

Inhibitory neurotransmitters such as glycine and GABA make a postsynaptic cell harder to depolarize by allowing "an influx of Cl-".

<u>Explanation:</u>

The neurotransmitters which have inhibitory influence on the neuron are termed as "Inhibitory neurotransmitters". The major inhibitory neurotransmitters involve serotonin and gamma-aminobutyric acid (GABA) in the brain and brain stem (spinal cord) respectively.

GABA uptake is temperature and ion-dependent as require both N a^{+} and C l^{-}. Even glycine transporters are also members of the large family of N a^{+} / C l^{-} dependent neurotransmitter transporters. Both of them with the GABA transporters share approximately 50% sequence identity.

A cross between heterozygotes for a single trait will lead to a genotypic ratio of 1:2:1. How many phenotypes will be observed i
Vladimir79 [104]

There will be 3 phenotypes observed if incomplete dominance is occurring in this organism.

<h3>What is incomplete dominance?</h3>

The so-called incomplete dominance is the one in which the alleles are expressed in heterozygosity, however, they produce an intermediate phenotype, since none is totally dominant. In the case of complete dominance, the phenotype is equal between zygotes and heterozygotes.

With these information, we can conclude that there will be 3 phenotypes observed if incomplete dominance is occurring in this organism.

As a small change in a person's DNA can cause a genetic disorder
zzz [600]

Affirmative, that is correct.

A genetic disorder is nothing more than an abnormal occurrence in a genome, which means that if you change DNA you'll change the genome, and if the change isn't acceptable, genetic disorders can occur easily.

Genetic disorders is a fun field within genetics, and it isn't easy. The functioning of a gene might be an easy concept now a days, but we haven't mastered it. For example, it's not like maths:

- Somebody comes up with a new, unsolved problem, and tries to solve it, and while doing that, the person can create laws, theorems, equations, etc.

Once you come up against a genetic disorder (you can't just create a genetic disorder to study it) you have to study the genetic disorder itself, what caused it and why.



Hope it helped,
