This deletion results in a polypeptide missing an amino acid. Cystic fibrosis is a genetic disease that affects mostly the lungs, but also other organs such as the pancreas and the liver. It is caused by a mutation in the gene cystic fibrosis transmembrane conductance regulator (CFTR). This mutation is a deletion of three nucleotides that cause the loss of the amino acid phenylalanine.

<h3>What are Neurotransmitters?</h3>

Neurotransmitters are endogenous chemicals that allow neurons to communicate with each other throughout the body.
Chemical synaptic transmission is primarily through the release of neurotransmitters from presynaptic neural cells to postsynaptic receptors.
There are a number of neurotransmitters used by the body for different functions, including acetylcholine, norepinephrine, glutamate, GABA, glycine, dopamine, and serotonin.
Glutamate is the principal excitatory neurotransmitter used in the brain.
GABA and Glycine serve as the major inhibitory neurotransmitters.

Answer:

Null hypothesis: male and female spiders organized in mating pairs don't differ significantly in respect to body length

Alternative hypothesis: male and female spiders organized in mating pairs exhibit significant differences in respect to body length

The application of one statistical test in order to obtain one p-value (probability value) may provide useful evidence to support the alternative hypothesis (or reject it).

The inference procedure uses the information collected from the sample in order to obtain one conclusion. Frequentism is a type of inference procedure that can be used to test a hypothetical test case, which is here represented by male and female spiders organized in mating pairs.
