A neurotransmitter is a chemical substance that is released by a nerve fiber due to the presence of nerve impulses; it transport chemical information from one nerve to the other. A receptor refers to a protein molecule that is found on the cell membranes of every cell, it functions by responding in an appropriate manner to chemical signals that are coming from outside of the cell.
The relationship between the neurotransmitter and the receptor is that the neurotransmitter molecules typically bound with the appropriate receptors and bring about the expected changes in the targeted postsynaptic cell.
Instructions in the DNA are first transcribed to RNA and the RNA is transported to the ribosome in the cytoplasm.
<h3>Transcription</h3>
Transcription is a process whereby the genetic instructions in the DNA of organisms are transcribed to RNA in the nucleus.
After transcription, the RNA which now carries the genetic codes is transported to the cytoplasm where it gets attached to the ribosome before the genetic codes are translated to their respective amino acids.

Answer:
Calcitonin- reduce blood calcium level
Parathyroid hormone- Raise blood calcium level
Explanation:
The thyroid gland is an endocrine gland which secrete its hormone in the blood directly. Both calcitonin and parathyroid hormone are released by the thyroid gland. Parathyroid hormone is released when the blood calcium level is low.
Parathyroid hormone increases the blood calcium level by osteoclast stimulation which releases calcium from bones and increases blood calcium level. Calcitonin is antagonistic to parathyroid hormone and it reduce the blood calcium level in the blood by stimulating the activity of osteoblast.
Answer:
More sunlight but less space.
Explanation:
The fallen tree would have let in more sunlight as it was blocking sunlight from getting in most of the time. Since the tree fell more sunlight will be able to get in. The only problem would the fact that there will be less space depending on the size of the tree and how it fell over.
