Based on their function, you would expect melanocytes in the skin to have a higher than usual number of ribosomes.
Ribosomes are cell structures that functions as the site of biological protein synthesis. Ribosomes are present in all living cells where they produce proteins required for many cellular functions. Ribosomes join amino acids together in the order specified by messenger RNA molecules. Ribosomes are made up of two parts which are; the large subunits (which connect amino acids to create a polypeptide chain) and the small ribosomal subunits (which read the RNA).
The nucleus intructs cells to do their activities
I don't understand its not my language I would like to help but I can't
Answer:
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.
Answer:
By action potential nerve contract the muscle
Explanation:
The muscle contract when the nervous system sends action potential to the muscle. So the nervous system delivers signal to muscle, the first signal reaches the neuromuscular junction. The signals are passed by a chemical messenger called neurotransmitter release by motor neurons, the chemicals bring reaction and shorten the muscle fibre. When neurotransmitter are absent or reduce in concentration the process reverse and muscle relax again.
