In the simulation, when protein molecules were evenly distributed on both sides of the membrane, was the solution isotonic, hypertonic, or hypotonic? Which direction was water flowing?

Answers

Answer 1

Answer:

1. Diffusion is the process of a substance moving from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion where water moves across a semipermeable membrane still from an area of high concentration of water to an area of lower concentration of water. This corresponds to water moving from an area with a low concentration of solute to an area with a higher concentration of solute.

2.

a. A semipermeable membrane allows some substances to pass through it.

b. The plasma membrane of a cell allows small uncharged molecules to pass through it, but not large molecules and not charged ions.

3.

a. The protein molecules were evenly distributed on both sides of the membrane, so this solution was isotonic.

b. In an isotonic solution, water moves both in and out of the cell, which was observed in the simulation.

4.

a. The protein molecules were more highly concentrated on the inside of the cell, so this solution was hypotonic.

b. In hypotonic solutions, water moves into the cell to help dissolve the higher amount of solute inside the cell, which was observed in the simulation.

5.

a. A semipermeable cell membrane is important to allow some molecules, like proteins, to be more highly concentrated inside the cell than outside the cell. If the cell membrane were permeable, the molecules on the inside of the cell would exit the cell and be evenly distributed in the cell and in its environment.

b. If the cell membrane were not permeable at all, the cell would not be able to receive nutrients from its environment.

Explanation:

Answer 2

When protein molecules were evenly distributed on both sides of the membrane, the solution is isotonic.

In isotonic solution the concentration of  solutes on side remain same .There is no net gain or less of water in isotonic solution.

What will be the direction of water flow in isotonic solution?The water will flow freely  across the cell membrane without any change in the concentration of solutes.In isotonic solution the cell neither shrink nor swell because the water concentration will remain same.

Which of the statements regarding the nitrogen cycle is true? a. Denitrification occurs when a nitrogen containing compound is produced from nitrogen in the soil. b. Atmospheric nitrogen is absorbed through the leaves of plants. c. Nitrogen fixation is the process atmospheric nitrogen is converted into biologically usable forms. d. Animals obtain nitrogen through the process of cellular respiration

Answers

Answer: Option C

Explanation:

The nitrogen cycle can be defined as the process by which the nitrogen is being recycled. The nitrogen is transferred from the atmosphere to the plants and then from plants to animals, human beings.

Then from animals and human beings it is again transferred into the soil and then atmosphere.

The nitrogen that is found in the sol is not in the usable form by the plants, nitrogen fixing bacteria converts it into usable form.
