Action potential in a motor neuron triggers the release of what neurotransmitter?
vodomira [7]

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.

How do scientists use DNA to support evolution?
guapka [62]
DNA supports evolution  because all life on Earth carries DNA, and evolution happens only after DNA changes. These changes are called mutations and happen spontanoulsy from flawed DNA copying or from mutagens, such as X-rays or chemicals.

Answer:

One significant difference that I noticed was the color of the water. In the control aquarium, the color of the water at 30 days was the same as it was on the 1st day. In the experimental aquarium, the water had a green tint on the 30th day, but on the first day it was clear.

True or false: The energy contained in the food we eat directly powers all of our cellular activities. If false, please make it
Gwar [14]

Answer:

False

"The energy contained in the food we eat is used to synthesize the energy that directly powers all of our cellular activities".

Explanation:

The food we eat undoubtedly contains energy. This energy is stored in the bonds of the molecules that make up the food. However, the food undergoes the process of digestion to yield glucose (a sugar). This glucose sugar is used in the process of CELLULAR RESPIRATION to synthesize a form of chemical energy usable by cells called ATP.

ATP or Adenosine triphosphate is a molecule that stores chemical energy in living cells. It is the molecule that directly powers all of our cellular activities. Hence, the statement in this question is FALSE. The correct statement should be "The energy contained in the food we eat is used to synthesize the energy that directly powers all of our cellular activities".
