Answers:
It is how oxygen and carbon dioxide travel across the cell membrane
Molecules travel with the concentration gradient
Explanation:
In simple diffusion, molecules move from an area of high concentration to area of low concentration until equilibrium is achieved. This occurs randomly unlike in facilitated diffusion where this flow is regulated through channels by facilitators. Nonetheless, these molecules still travel down the concentration gradient, similar to simple difussion.
Answer: Active transport
Explanation:
In this type of transport, energy is required. This is especially because, in endocytosis and exocytosis, the membrane has to form some structure (some form of a vessicle) to facilitate these transport modes. This requires energy from ATP. More so, usually transport in this case is against concentration gradient.
Answer:
Osmosis.
Explanation:
Osmosis is the movement of water from a lower concentrated solution to a higher concentrated solution through a semi-permeable membrane. In this case, the cell membrane has pores that allow only water molecules to pass through but the solute molecules are too large to pass through. Therefore only water is moving down its concentration gradient.
