Answer:
False.
Explanation:
Cell membrane is made of the lipids and proteins with the attached moieties of carbohydrates. The plasma membrane is the selectively permeable membrane that allows the diffusion of some selected particles only.
The transport along the cell membrane depends on the size and the hydrophobicity of the molecule. The size of oxygen is although higher than magnesium but to its highly hydrophobic nature it can easily pass through the plasma membrane as compared with the magnesium. The oxygen diffuses out faster than magnesium.
Thus, the answer is false.

The brainstem can be defined as a structure which is present in between the midbrain and the cerebrum. This controls the flow of information from the brain and the rest of the body. It also controls the functions like breathing, heart rate, consciousness, sleep and wake cycle and blood pressure. The brain stem consists of pons, midbrain and medulla oblongata.
The part of the amino acid that gives the molecule its unique or characteristic chemical properties would be the R-group. Every amino acid has three main groups in it namely the amino group, carboxyl group and the R group. "R" represents different organic chain that is specific to a certain amino acid which gives different properties of the molecule.
