answer:

Coal is formed by the decomposition of dead plant and animal under the earth for millions of years under heat and pressure.

This leads to the formation of coal.

Coal is termed as non renewable source of energy as it takes millions and thousands of years for the formation of a small quantity of coal.

Coal is considered a non renewable source because the earth cannot replenish it.

if you were to watch an individual neurotransmitter molecule just after it was released what would happen to it

Olenka [21]

Neurotransmitter leaves the presynaptic cell by exocytosis. It is released in the synaptic space, and moves to the postsynaptic membrane to meet its receptor. When binding occurs, it triggers a response in the new cell.

-----------------------------------------

Every neuron forms connections with another cell.

When a presynaptic cell sends information, a neurotransmitter is released.

After the exocytosis event, this chemical substance travels through the synaptic space forward to the other cell. Once there, it binds to its receptors in the postsynaptic membrane.

When the joining occurs, the receptor acquires a channel shape. This change allows the ion transference that will make possible the modification of the action potential.

This binding produces the excitatory postsynaptic potential -depolarization-.

A new action potential initiates in the postsynaptic cell and spreads to the rest of the membrane, depolarizing it.

If the communication between cells needs to stop, the neurotransmitter will be taken out from the synaptic space instead of binding to its receptor.

There are two mechanisms by which the neurotransmitter can be eliminated: by deactivation or reuptake.

If you have a hamster with long fur, what possible genotypes could the hamster have?

Vadim26 [7]

Answer:

Ll, Ll, LL

Explanation:

So, there is one thing we must remember to answer this:

1# dominant genes(long fur) are expressed over reccesive genes(short fur)

Knownign that dominant is over reccesive, it is simple. If the genotype was Ll or lL then the dominant long fur would be expressed over reccesive short fur. Long fur - Ll, lL

Next, we know that LL will be long fur since its both long and long, and there is no possibility for short fur. Long fur - LL

Finally. we have ll, and since there isnt a dominant long fur, and only reccesvie short, then this cannot be long fur. Short fur. - ll

The one on the bottom

bonufazy [111]

Natural selection or survival of the fittest can cause a major evolution as the species at risk need to stay alive and therefore need to become more adapted to the situation at hand. The species can evolve through generations to become more crafted to the predatorial habits of their predators. If the females are less at risk than the males then the males might evolve to become more protected or if some of the species live in a different situation maybe not even that far away, that can have a big impact on the evolutionary habits of the species at hand.

I hope I'm right

What happens to the undigested Good in the body?

Tanzania [10]

It shows up in your stool. Specifically the undigested food includes material that cannot be absorbed by the vili found in the small intestine. Thereafter the material moves to the large intestine, goes through the bowel tract, turns into feces and exits the GI tract via the rectal cavity
