The bacterial genus that is mannitol salt agar selective is Staphylococcus. Mannitol salt agar or known as MSA is often used in culture of certain bacteria since it is selective and is a differential growth medium. It would only encourage growth specific group of bacteria and inhibit other growth. It is very important in medical studies and laboratories as it is able to determine pathogenic microorganisms in a short time. It has a high amount of salt making it selective only to gram positive bacteria like the Staphylococcus and the Micrococcaceae. The salt level is about 7.5% to 10% which is inhibitory to many bacteria.

Answer:
francium
Explanation:
The most expensive natural element is francium, but it decays so quickly it can't be collected to be sold.
Answer:
The correct answer is - through facilitated diffusion and active transport.
Explanation:
Glucose is a six-carbon sugar molecule that is directly utilized by cells to provide energy. A glucose molecule is large enough to go through a cell membrane with simple diffusion.
Cells help glucose molecules to cross the cell membrane through facilitated diffusion and active transport. Active transport is of two types primary and secondary active transport to help the glucose molecule to cross the membrane.
Thus, the correct answer is - through facilitated diffusion and active transport.
