Question

I need everyones help please

Answer 1

Correct options and their explanations:

Part A.

Correct option: C ( Diffusion).

Diffusion is the movement of a substance from an area of high concentration to an area of low concentration.

NaCl concentration is more outside the cell than inside the cell. So it will diffuse through cell membrane, from high concentration to low concentration.

Part B.

Correct option: C ( into the cell).

Ions ( Na+, Cl-) are more outside the cell than inside so they will move through cell membrane, from high concentration to low concentration, outside to inside the cell.

Part C.

Correct option: B (occur into the cell).

As NaCl concentration is more outside the cell than inside the cell.

Net diffusion = Diffusion into the cell + Diffusion outside the cell

So the net diffusion occurs into the cell.

Part D.

Correct option: D (occur in both directions)

Diffusion of water will be in both direction depending on the concentration of solutes, inside and outside the cell. First water will diffuse outside then inside the cell.

Part E.

Correct option: D (occur outside the cell).

Under these conditions, NaCl concentration is more outside the cell than inside the cell. So water will move oppositely from inside to outside the cell.

Part F.

Correct option: B (hypertonic).

A hypertonic solution is a particular type of solution that has a greater concentration of solutes.

Hence salt solution compared to blood will be hypertonic. because it has more salts concentration than blood.

Answer 2

Part 1.

The option C (diffusion) is correct option.

• According to condition NaCl concentration is more outside the cell than inside the cell.
• So it will diffuse through cell membrane, from high concentration to low concentration.

Part 2.

The option C is correct which is into the cell.

As the concentration both ions is more outside the cell so they will diffuse through cell membrane, from high concentration to low concentration.

Part 3.

The option B is correct which is occur into the cell.

According to condition NaCl concentration is more outside the cell than inside the cell.

So the net diffusion occurs into the cell.

Part 4.

The option D is correct option.

The diffusion of water will be in both direction. First it will be outside the cell, then inside the cell.

Part 5.

The option D is correct option.

• Osmosis the movement of water from its high concentration to low concentration.
• So concentration of water is low outside the cell. Hence osmosis will be outside the cell.

Part 6.

The option B is correct.

The salt solution compared to blood will be hypertonic.

• A hypertonic solution is a particular type of solution that has a greater concentration of solutes.
• Since blood has low salt than solution so solution will be hypertonic.
