The right answer is C.

Sulfur purple bacteria (also called sulfooxidative phototrophic bacteria) are part of the family of photosynthetic bacteria with green sulfur bacteria and cyanobacteria. However, unlike cyanobacteria, purple bacteria such as sulfurous green bacteria do not produce oxygen during photosynthesis. In the sulfur oxidation-reduction process, these bacteria oxidize sulfide (H2SO3) to elemental sulfur (S).

sweet-ann [11.9K]

Answer:

It's possible.

Explanation:

It said if they were nearly as smart as humans. They never said if they were as capable as Humans. Naturally, some would be smarter than others so some might be able to live here but others might have to have their own country. So, it is likely that some Neanderthals will be able to live in modern society, though not all.

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.
