Answer:
Her immune system is exhibiting the second line of defense. This defense is part of innate immunity.
Explanation:
The situation above is related to the<em> body's immune system.</em>
The<em> immune system is the defense system in the body that enables an individual to fight against a particular disease or infection.</em> It defends the body through its three lines of defenses, <em>first line, second line and third line</em>.
The first line of defense refers to the outer covering or barrier of the human body such as the <u>integumentary system, particularly referring to the skin.</u> The second line of defense refers to non-specific immune cells such as <em>dendritic cell, macrophages and neutrophils.</em> The third line of defense refers to the <u>adaptive immune system. </u>This consists of highly specialized cells that removes the pathogens and inhibit their growth.
Nina is exhibiting the second line of defense because of her symptoms. The presence of her high fever means that her body is fighting the infection. It is at the second line of defense that the immune system helps protect the body.
This defense is part of the<u> innate immunity.</u> This is also called "Nonspecific Resistance." This type of immunity involves the immune system fighting the body's invader. It is nonspecific and doesn't target any individual. Inflammation and fever is part of this immunity.
Nina is exhibiting high fever, thus the defense is part of the innate immunity.

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.
