Answer:
Explanation:
Oxygen moves onto red blood cells when they are close to the lungs because oxygen needed by cells of other parts of the body is carried by the red blood cells and the only the lungs makes this oxygen available to the body and also ensures to remove other harmful gases such as CO2. Thus, red blood cells must be able to absorb oxygen in the lungs, pass through narrow blood vessels, and release needed oxygen to respiring body cells.

Answer:
a) polar heads on the outside and nonpolar fatty acids on the inside
Explanation:
The cell membrane is made up of phospholipids arranged in a bilayer, where hydrophilic polar (negatively-charged) heads of phospholipids interact with water molecules (i.e., aqueous surrounding media). Moreover, non-polar (uncharged) fatty acid tails are hydrophobic because they cannot be dissolved in water. Thus, the bilayer cell membrane is a structure where non-polar fatty acid chains are localized in the inner region (away from the water), while hydrophilic phosphate heads face outward, interacting with water on both sides of the cell membrane.
