Front

What type of solution is a red blood cell in when there is equal movement of water in and out?

Back

Isotonic solution

Front

What is the main sugar produced by plants during photosynthesis?

Back

Glucose

Front

What is an isotonic solution?

Back

A solution where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes outside the cell, causing water to move out of the cell.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes outside the cell, causing water to move into the cell.

Front

What is the significance of the density of ice in aquatic ecosystems?

Back

It allows ice to float, insulating the water below and providing a habitat for aquatic life.

Front

What are lipids?

Back

A group of organic compounds that are insoluble in water, including fats, oils, and waxes.
