Answer:

It's a Bilayer

Explanation:

<em>The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules. ... The cell membranes of almost all organisms and many viruses are made of a lipid bilayer, as are the nuclear membrane surrounding the cell nucleus, and membranes of the membrane-bound organelles in the cell.</em>

A cell membrane is a bilayer made up of phospholipids. The hydrophobic tails of the lipids make up the inside layer of the membrane while the hydrophilic heads touch the fluid both outside and inside of the cell

Natali5045456 [20]

The question is incomplete, the complete question is:

A client with myasthenia gravis improves and is discharged from the hospital. The discharge medications include pyridostigmine bromide (Mestinon) 10 mg every six hours. The nurse evaluates that the drug regimen is understood when the client says, "I should:

1

Take the medication on an empty stomach."

2

Set an alarm so I take the medication on time."

3

Take my pulse rate before taking the medication."

4

Monitor for an increase in blood pressure after taking the medication."

Answer:

The correct answer is statement 2.

Explanation:

Pyridostigmine refers to an essential drug, which must be consumed on time, as a late or missed dose can lead to extreme neuromuscular and respiratory consequences or even death. Pyridostigmine should be consumed with a small concentration of food in order to inhibit gastric irritation.  

It is not essential to take the pulse rate prior to taking the medication. Pyridostigmine may result in hypotension, however, not hypertension, which is not an indication of cholinergic crisis.

We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the _________ group
Alina [70]

Answer: Option B) phosphate; hydroxyl; 3'

We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the phosphate group attached to the 5' carbon atom of the sugar portion of a nucleotide and the hydroxyl group attached to the 3'

carbon atom

Explanation:

For both RNA and DNA, chemical groups such as phosphate (PO3-) attaches to the 5' carbon of the pentose sugar (deoxyribose in DNA, ribose in RNA).

While hydroxyl group (OH) attaches to the 3' carbon atom of the pentose sugar.

Thus, a nucleic acid structure structure reveals a several repeating units of nucleotides where nitrogenous base links to a pentose sugar, who in turns is linked to phosphate group

Blood cells are _____ in shape because they lack a nucleus.
sesenic [268]


Red blood cells are disc shaped. It is thought one factor that allows them to have this shape is because they do not have a nucleus. This tends to increase amount of space inside the cell for hemoglobin.

They have a flexible disc shape which helps increase the surface- to- area volume ratio  which enables oxygen and carbon dioxide to diffuse across the red blood cell's plasma membrane more readily.

Their disc shape also enables them to squeeze through tiny capillaries that are half their size .
