Answer:
87 mg
Explanation:
To find the dose of acetaminophen for a 3-year-old child with the body surface area of 0.30 m², we use the formula given below
Child dose = child surface area/1.73 × adult dose
Given that the child surface area = 0.30 m² and the adult dose = 500 mg,
Child dose = child surface area/1.73 × adult dose
Substituting the values of the variables into the equation, we have
Child dose = child surface area/1.73 × adult dose
Child dose = 0.30 m²/1.73 × 500 mg
Child dose = 0.1734 × 500 mg
Child dose = 86.71 mg
Child dose = 87 mg to the nearest whole number
Answer:
Option A, Release of chemical signals by keratinocytes that have been damaged by UV light will increase the production of melanin.
Explanation:
Negtaive feedback mechanism of homeostasis maintains the stability of any internal condition or function through lessening of output of a system or through slow down of a functional system.
Here in this case the keratinocytes function is reduced by damaging them on exposure to UV light which further triggers the release of chemicals that enhance the production of melanin.
Hence, option A is correct
Answer:
There is no short answer.
Explanation:
Antigen presenting is a term used to describe the action of introducing them to the white blood cells and triggers the production of T cells which are essential to the immune system.
If we complete the sentences given in the question and put them in order;
1 - The antigen presenting cell encounters and processes the antigen.
2 - With the antigen, the antigen presenting cell migrates to the nearest lymph node.
3 - The antigen presenting cell displays the antigen to the T cells.
4 - The T cells initiate the immune response if the antigens are viral proteins or abnormal antigens.
5 - Infected or malignant cells are then destroyed before they can do further harm to the body.

Explanation:
Agonists bind to cell receptors and antagonists also bind to cell receptors.
<h3>What are agonists?</h3>
An agonist is any substance that is similar to a neurotransmitter and therefore these molecules have strong effects on a particular signaling pathway.
An antagonist is another class of molecules that oppose the effects of the agonist by inhibiting its mechanism of action and therefore these substances also need to bind receptors.
In conclusion, agonists bind to cell receptors and antagonists also bind to cell receptors.
