Answer:

The outer layer of a cell that acts as a gatekeeper to a cell is the Cell Membrane or Plasma Membrane.

The cell membrane made up of mostly phospholipids and proteins and is known as selectively permeable membrane as it allows the entry of some selective molecules into it.

The plasma membrane is the layer present between  the cell and its external  environment. As the gatekeeper takes care of entry, cell membrane also regulates the molecules that enters and exits the cell from external environment.

Cells membrane helps in maintaining appropriate amount of molecules to function inside them.

Hence, the correct option is Cell Membrane.

1. <span>what is the amount of the bolus dose, in both milligrams and milliliters, that you will administer in the first minute? 
</span>The doses is 0.9 mg/kg and the weight of the patient is 143 pounds. So, the total doses of drug needed will be: 
Total doses= 0.9 mg/kg * 143 pounds * 0.453592 kg/pound= 58.37 mg.

10% of the doses will be given bolus for 1 min, so the amount would be:
Bolus doses= 10%*58.37 mg= 5.837 mg.
In mililiters, it would be: 5.837 mg * 1ml/mg= 5.837 ml.

<span>2. what is the amount of the remaining dose that you will need to administer?
The remaining dose would be 90% of the total dose. You can either calculate it directly or subtract the bolus doses from the total doses.
Remaining doses= total doses- bolus doses= </span>58.37 mg- 5.837 mg= <span>52.533mg</span>
