The FDA requires retention of investigational drug study records for The answer is C. At least two years after the investigational drug's approval by the FDA
An investigator shall retain records needed to be preserved under this part for a period of two years following the date a marketing operation is approved for the drug for the explanation for which it is being investigated
Answer:
The balloon drifts in a counterclockwise direction from 9:00 a.m. to 12 (Midnight) 3.
<span>Sam, a mendalien with black eyes and green skin, has a parent with orange eyes and white skin. Sam has a dominant phenotype expressed but he has a parent with a recessive phenotype which means he has a heterozygote gene.
Carole is a mendalien with orange eyes and white skin. Since Carole express both recessive phenotypes she should be homozygote recessive.
The key to this problem is how Sam dominant gene will be inherited. Since there are two heterozygote genes, it will be 50% dominant gene inherited for each phenotype. Then the result should be:
25% Dominant + Dominant =</span>black eyes and green skin<span>
25% Dominant + Recessive =</span>black eyes and white skin
25% Recessive + Dominant =orange eyes and green skin
25% Recessive + Recessive =orange eyes and white skin

A neurotransmitter can have an excitatory or inhibitory effect on the postsynaptic cell, depending on <u>which of its </u><u>receptor(s</u><u>) are present on the </u><u>postsynaptic</u><u> (target) cell.</u>
<h3>How do excitatory and inhibitory neurotransmitters act?</h3>
Sometimes neurotransmitters can bind to receptors and cause an electrical signal to be transmitted through the cell (excitatory). In other cases, the neurotransmitter can prevent the signal from continuing, preventing the message from being carried (inhibitory).
With this information, we can conclude that a neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse.
