Answer:
Action potential in a motor neuron triggers the release of acetylcholine (ACh) neurotransmitter.
Explanation:
Acetylcholine: It is a neurotransmitter released by motor neurons which bind to the receptors end plates of the motor. When an action potential travel down the motor neuron's axon, neurotransmitter release occurs resulting in an influx of calcium and altered permeability of the synaptic terminal membrane.
The Ca2+ ions allow synaptic vesicles to move and bind with the presynaptic membrane which is present on the neuron and released neurotransmitter from the vesicles into the synaptic cleft. Once it's released ACh diffusion occurs across the synaptic cleft to the motor end plate, and binds with ACh receptor. As the neurotransmitter ACh binds, these ions channel open and sodium ions cross the membrane into the muscle cells.
In this phase reduction of voltage inside and outside the cell occurs, which is known as depolarization. When ACh binds to the motor end plate this depolarization is known as end plate potential. Then depolarization spread with the sarcolemma and creating an action potential. This action potential moves the entire cell and creating a wave of depolarization.
The question answered by the information from the Punnett squares is Can furred mice produce furless mice?, 3rd option.
<h3>How does law of segregation apply to Punnett square?</h3>
A Punnett square can be used to predict genotypes which are allele combinations and observable traits, phenotypes of genetic cross offspring. When an organism produces gametes, each one receives only one gene copy, which is chosen at random. This is known as segregation law.
Mendel's law of independent assortment applies to genes rather than chromosomes. In humans, a single chromosome can contain over 1,000 genes. In this study, homozygous furred and furless mice and heterozygous F1 rats answers the question "Can furred mice produce furless mice?" from the Punnett squares.

Answer:
The answer is the second one so B.)
Explanation:
Answer:
The cilia is one of the things that act defensively in the respiratory system.
Explanation:
It propels a mucus-like liquid that covers the airway which traps pathogens (potentially infectious microorganisms) and other particles, preventing them from reaching the lungs.
As the amount of sunlight we see reflected increases, it is called WAXING.
