I think it's A
the cell membrane contain protein molecules
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.
An enzyme works like a key to a lock. If it finds the right thing it can work.

Answer:
Red algae
Explanation:
Coral reefs are the structure which are one of the some most important underwater ecosystems of the world. They are characterized by the formation of roof-building corals which are basically the colonies of dead or living polyps(corals) attached together through deposition of calcium carbonate.
Red algae has an important role in the formation of coral reefs because their thread like structure traps the particles present in the sand of water which ultimately gives the algae a mechanical support for their growth as well as the formation of coral reefs.
