Answer:
D. "You can take acetaminophen, also known as Tylenol, for pain, but no more than 3000 mg per day."
Explanation:
Due to the large bruise on the patients thigh, he would need medications to relieve him from pain.
As the patient states, he is a truck driver and needs to stay awake. The best medication will be the one that does not cause drowsiness.
Therefore, it will be appropriate for him to take acetaminophen sold by the brand name Tylenol. It does not cause drowsiness like opoids.
1000 mg per day will not be sufficient, however the maximum dosage is 3000 mg per day.
Answer:
"As a molecule moves through the plasma membrane it passes through <em>a hydrophilic layer of phospholipid heads then a hydrophobic layer of phospholipid tails and then another hydrophilic layer of phospholipid heads".</em>
Explanation:
Biological membranes are formed by two lipidic layers, proteins, and glucans.
Lipids characterize for being amphipathic molecules, which means that they have both a hydrophilic portion and a hydrophobic portion at the same time. These molecules have a lipidic head that corresponds to a negatively charged phosphate group, which is the polar and hydrophilic portion. They also have two lipidic tails that correspond to the hydrocarbon chains -the apolar and hydrophobic portion- of the fatty acids that esterify glycerol.
Membrane lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane.
Through this lipidic bilayer, some molecules can move from one side of the cell to the other, which happens because of concentration differences. When this occurs, molecules must pass through the hydrophilic layer of phospholipid heads then through the hydrophobic layer of phospholipid tails and then again through another hydrophilic layer of phospholipid heads.
If you are talking about the amount of material, it will be equivalent. But monomers are usually smaller than polymers.
