Answer:

Standard anatomical position is the agreed-upon reference for body position when studying anatomy (option 2).

Explanation:

Anatomical position consists of the placement of the human body for its anatomical study, following certain norms established and accepted by convention.

The body is observed from its front face.
The members must be extended, showing their ventral surface and with a slight separation from the rest of the body.
The hands show the palms, while the feet are hyperextended showing their backs.

This position is useful to provide the description of any area of the body in a specific posture, and that can be understood even by those who do not observe.

The other options are not correct because:

1) Histological, refers to the study of cells and tissues.

3) Superior, is a directional term, indicating something located at the top of the body or closer to the head.

4) Mnemonic refers to the association of words used to remember names or lists of names.

Bad White [126]

Answer:

4 tablets t.i.d. (Three times a day)

Explanation:

By use of Dimensional Analysis, you can figure this out:

First, find how many mg she will take in a day:

$(132 lbs)(\frac{0.454 kg}{1 lbs})=59.9 kg\\(59.9 kg)(\frac{70 mg}{1 kg} )=4,195mg\\$

Since she will take 3 equal doses, divide this by 3:

$\frac{4,195 mg}{3} =1398\text{ mg dose}$

To find the # of tablets per dose, divide dose in mg by mg per tablet:

$(\frac{1398 mg}{dose})(\frac{1 tablet}{350 mg} )=3.995\frac{tablets}{dose}$

Since you can't realistically take .995 of a tablet, round up to 4.

What will happen if you lose all of your Tcells?

Leno4ka [110]

Answer:

This is why Killer T-cells are also called Cytotoxic T-cells. The pieces of destroyed cells and viruses are then cleaned up by macrophages. The other type of T-cell is the Helper T-cell. When a T-cell finds its virus match in your body, it makes many copies of itself to attack that virus.
