Answer:

Tyrosine.

Explanation:

Tyrosine is a non-essential amino acid, it is part of proteins and is considered an aromatic amino acid. Its synthesis occurs from the hydroxylation of phenylalanine as long as it contains an adequate supply of this amino acid.Phenylketonuria is a hereditary disease whose main treatment is dietary restriction of the amino acid phenylalanine. People with phenylketonuria may have low levels of the amino acid tyrosine in their blood.Phenylalanine hydroxylase is an enzyme that converts phenylalanine to tyrosine. Deficiency of the enzyme phenylalanine hydroxylase is a congenital error of metabolism.

In the state of washington, the prevailing winds blow eastward off the ocean and up and over two mountain ranges. biologists are
stepan [7]
The fern should be found on the west side of the mountain ranges at higher elevations because the prevailing winds are from the west off the Pacific Ocean so bring moisture in the clouds and as the clouds rise up over the westernmost mountains they cool off and precipitate so in the warm seasons rain would be concentrated in this area and higher up would be cooler.

Transcription is the process by which the DNA molecule makes an RNA molecule using enzyme RNA polymerase and other proteins. The mRNA is then used to generate proteins by a process called translation which occurs in the cytoplasm. Transcription occurs in the nucleus because DNA cannot leave the nucleus.

Do you think osmosis occurs when a cell is in an isotonic solution explain your reasoning
Bumek [7]
The word isotonic is used to refer to the solutions (two solutions) which have the same osmotic pressure in both sides of the semipermiable membrane. The condition allows the free movement of water across the membrane. However, this does not change the concentration of the solution across the membrane. 

Hence, osmosis may not occur in this condition.
