Biology
1 answer:
Dennis_Churaev [7]3 years ago
4 0

Answer:

The objective itself is usually a cylinder containing one or more lenses that are typically made of glass; its function is to collect light from the sample.

Explanation:

A telescope mirror can be made from glass that is somewhat less pure than that used to make a lens, since light does not pass through it.

Aneli [31]

Acetylcholine broken down is the process by which this neurotransmitter activates a suitable ligand-receptor to trigger a cell signaling pathway.

<h3>What is Acetylcholine?</h3>

Acetylcholine is a chemical messenger (i.e., a neurotransmitter) that is used to transmit signals inside the body.

Acetylcholine broken down is due to its hydrolysis, which ends cell signaling between brain synapses.

In conclusion, Acetylcholine broken down is the process by which this neurotransmitter activates a suitable ligand-receptor to trigger a cell signaling pathway.

How the process of natural selection canexplainhow evolution occurs?
harkovskaia [24]
In natural selection, there are three main things you need to know. There must be a variance in the genepool of course, or else to selection or evolution will take place. There also must be a selective force and time. Now, lets say that there is a population of many colored moths. But lets say that the brown colored moth blends in with the environment. This means that predators (selective force in this case) will have a much harder time finding these brown moths instead of easily finding some of the other colored moths (variation). This means that the brown moths will survive at a much higher rate because the are harder to find, and over time, the gene pool will narrow down to just brown moths because the rest of the moths die out due to predators and competition. This also means that this moth species has evolved over time to just become the brown colored moths only. Hope you can understand this but feel free to ask for clarification.
