Answer:
A PICC line is a long catheter inserted through the veins of the antecubital fossa.
Explanation:
PICC (peripherally inserted central catheter) that are mainly used as a part of chemotherapy for the administration of the particular substances. This can be used for the long period of time in the individual.
The long catheter is inserted in the body through the skin mainly at the peripheral site of the body. This can be inserted for the weeks depending on the severity of treatment. The veins of the antecubital fossa is used for the insertion of the tube.
Thus, the correct answer is option (3).
Tyrosine is listed as a non-essential amino acid because it can be synthesised from the essential amino acid phenylalanine.
<u>Explanation:</u>
Amino acids are classified as essential and non essential according to whether they can be synthesized in the body itself or should be supplied by the diet. Essential amino acids cannot be synthesized in the body of the organism and thus can be obtained only from the diet. In the case of human beings, valine, phenylalanine, methionine etc are examples of essential amino acids.
Non essential amino acids can be synthesized within the body of the organism. Thus they need not be supplied by the diet. Alanine, aspartic acid etc are some of the non essential amino acids in human beings. It is given here that animals cannot synthesize tyrosine from shikimate-3p due to the lack of EPSP synthase.
But the amino acid tyrosine can be synthesized from the amino acid phenylalanine which is an essential amino acid. Thus tyrosine will be a non-essential amino acid.
Animal fats and hydrogenated vegetable margarine contain saturated triglycerides. Saturated triglycerides are those that are made of saturated fatty acids. These saturated fatty acids are capable of forming atheroma (/plaques) along arterial walls, causing atherosclerosis or arteriosclerosis. These could both result in coronary thrombosis (blocking of a coronary artery by a clot of blood), and hence a myocardial infarction (heart attack).
