The answer would be C) The solute concentration is equal on both sides of the cell membrane.
This is correct because in an isotonic solution, they would have the exact salt concentration as the blood surrounding the cell. There won't be an effect on the surrounding cells. So, the cells won't gain or loose any water.
Hope this helps!:)

Answer:

The correct answer would be - Cells begin dividing faster, leading to cancer.

In the process of the cell cycle, there are several checkpoints that ensures that the cell is all set to move to next phase, the cell that not match the requirements cell have not move to next phase.

These checkpoints control the rate of cell proliferation or division and if a dividing cell fails to pass through any checkpoints due to the mutation, it is most likely divide uncontrollably and lead to cancerous or tumor cell.

What are the roles of light, carbon dioxide, and water

yuradex [85]

Answer:

The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas. After the sugar is produced, it is then broken down by the mitochondria into energy that can be used for growth and repair.

Answer:

For the Venn Diagram

1 - definite shape (E)

2 - definite volume (B)

3 - definite mass (A)

4 - takes the shape of the container (F)

5 - indefinite volume (D)

For the questions

1 - A - definite mass

2 - B - definite volume

3 - F - takes the shape of a container

4 - E - definite shape

5 - D - Indefinite volume

Explanation:

Definite - Specific

Indefinite - cant be determined

Remember (this is probably the most important note)

ALL MATTER HAS MASS!

A solid is the only state of matter that has a specific (definite) shape

Liquids and gases do not have specific shapes but they can take the shape of containers. Examples would be a glass of water or even just a water bottle full of air

Gas has an indefinite volume. As you can see in the image below gas molecules looser than liquid and solid molecules therefore it does not have a specific volume.

Liquids and solids have definite volumes as they can be easily measured
