B
Energy is needed to move sugar from low to high concentration while using a membrane protein.
Explanation:
The reason that energy is needed in this process is that the movement of the molecules is moving up the concentration gradient. This means decreased entropy and increasing Gibbs's free energy.
This is not a spontaneous process and therefore energy input is required. It is called active transport. This is why ATP energy is used to power the process. Atp enables the transmembrane proteins to change conformation and transport the sugar molecules into the cell.
In facilitated diffusion, while the molecules are facilitated by membrane proteins, no energy is input because the molecules are still traveling down the concentration gradient.

Explanation:
During quiet breathing, the diaphragm and external intercostals must contract. A deep breath, called diaphragmatic breathing, requires the diaphragm to contract. As the diaphragm relaxes, air passively leaves the lungs. A shallow breath, called costal breathing, requires contraction of the intercostal muscles.

Answer:
IT IS BEST FOR A CELL TO HAVE A LARGE SURFACE AREA AND A SMALL VOLUME. THEREFORE, A LARGE SURFACE AREA TO VOLUME RATIO IS MORE DESIRABLE.
