Shannon thinks that the color of light will affect the growth of pea plants. She set up two experiments – Group A: plants are placed under white light (representing the sun) and Group B: plants are placed under blue light. Every 3 days for a month she measured the height of the plants to see if they have grown and places her data in her data table. What is the independent variable?

The color of light

A red blood cell is placed in distilled water. List the following:

1. What type of solution is the cell in? (hypotonic, hypertonic, isotonic)
2. What can be expected to happen next?
1. hypotonic
2. Osmosis will cause water to move into the cell, causing the cell to swell and possibly burst.
