Explanation:
Answer:
A neuromuscular junction is a junction between a <em>nerve fiber</em> and a <em>muscle cell.</em>
Explanation:
<em>A neuromuscular junction (or myoneural junction) is a site of chemical communication between a nerve fiber and a muscle cell, is analogous to the synapse between two neurons. </em>
A motor neuron is able to transmit a signal to the muscle fiber, causing muscle contraction upon stimulation by a nerve impulse, the terminal releases the chemical neurotransmitter acetylcholine from synaptic vesicles binding to the receptors, the channels open, and sodium ions flow into the endplate, this initiates the end-plate potential, the electrical event that leads to contraction of the muscle fiber.

Answer:
Explanation:
a. Since both the parents are carriers, they have one allele that is the gene for the normal trait and one gene that is for the sickle cell trait. So the genotypes of the parents are Hh
b. If we use a punnett square:
H h
H HH Hh
h Hh hh
Genotypic ratio: 1 HH: 2Hh: 1hh
Phenotypic ratio: 1 normal blood cell: 2 sickle cell carriers: 1 sickle cell disease
The process is known as the greenhouse gasses effect
