Heat can be absorbed or produced
Answer:
The answer is: phospholipid molecules
Explanation:
The plasma membrane of a cell is consists of a lipid bilayer. This lipid bilayer, also known as the phospholipid bilayer, is a polar membrane composed of two layers of lipid molecules, usually amphipathic phospholipid molecules.
The amphipathic phospholipid molecules have a hydrophilic phosphate head on the exterior and a hydrophobic tail consisting of fatty acid chain on the interior of the membrane.
13111 is already an integer (whole number). It also can be expressed as 1 ton or 13111000g.
The total mass is 10.57+6.96=17.53 g.
So, the percent by mass of magnesium is (10.57)/(17.53) * 100 = <u>60.3%</u>
<u />
The percent by mass of oxygen is (6.96)/(17.53) * 100 = <u>39.7%</u>
