I agree because in some cases the student might be bullied or have problems with poor hygiene and not notice. Even though some teacher’s don’t discuss it with students with poor hygiene I feel like it should be Made aware so that they don’t become self conscious and bullied for it and there’s many ways teachers can help Students with poor hygiene but they should never not let the student know about it because in most cases it doesn’t benefit the teacher or the student at all.
This is true. If it has nothing or little to do with genetics than it is a skill based action, practice and repetition can help improve these.
Answer:
The correct answer is A. Tyrosine should be taken in through the diet as the body is unable to produce it.
Explanation:
Tyrosine is an organic chemical compound. It performs important biological tasks as an intracellular transmitter (it can be phosphorylated by protein kinases), and is also a precursor to important hormones and biologically active substances (thyroxine, triiodothyronine, adrenaline, noradrenaline and dopamine).
It is an endogenous amino acid, which means that the human body and most animals are able to synthesize it provided that there is sufficient supply of phenylalanine, from which tyrosine differs by the presence of one hydroxyl group.
Tyrosine is very important for the proper functioning of the thyroid and pituitary gland. Lack of this amino acid causes hypothyroidism, which can manifest itself in the form of fatigue and exhaustion. Reducing the amount of tyrosine in the body causes a deficiency of norepinephrine and dopamine, which can cause depression.
