A membrane which limits the type of molecules which will pass through it is called a semi permeable membrane.

A semipermeable membrane is a membrane which can be biological or artificial, that will allow the movement of certain molecules through them by diffusion. Several factors such as pressure, concentration, temperature of the molecules on each side, and also the permeability of the membrane to each solute determine the rate of passage of the molecules.

Naily [24]

be slower at absorbing nutrients than the other cell

Explanation:

The cell without the microvilli will be expected to have as slower absorption rate of nutrient than the other cell.

  • Microvilli are finger-like projections from the surface of the cell.
  • The structure has a large surface area to volume ratio which allows for nutrient to be absorbed easily.
  • These structures are very important during the absorption of digested food in cells.

Cells without this structure will not absorb food faster.

The solutions in the two arms of this U-tube are separated by a membrane that is permeable to water and glucose but not to sucro
DaniilM [7]

Answer:

The correct answer to the question is: the level of liquid in Side A will rise.

Explanation:

  • Sucrose is formed of two molecules of glucose but the membrane is impermeable to it.
  • The given membrane is said to be permeable to water and glucose.
  • Through a semi-permeable membrane, molecules tend to move from a region where its concentration is high to another region where its concentration is low by the process of diffusion until its concentration in the two regions becomes equal. This phenomenon is known as Osmosis.
  • Concentration gradient of a molecule can be defined as the difference in the concentration of the molecule in two different regions separated by a semi-permeable membrane.
  • Considering glucose, the concentration of glucose is low in side A (1M) and high in side B (2M), so it will tend to move from side B to side A down its concentration gradient.
  • Considering sucrose, although its concentration is high in side A (2M) but low in side B (1M), it is unable to move as the membrane is impermeable to it.
  • Water tend to move from a region where the concentration of solute is low (or water concentration is high) to a region where the concentration of solute is high (or water concentration is low).
  • Due to the movement of glucose from side B to side A, the concentration of total solute concentration becomes high in side A as compared to side B. Therefore, water would move from side B to side A.
  • Hence the level of liquid in Side A will rise after sometime.
