can you guys help me with my bio lab, please. it will be due tomorrow

PROCEDURE:

- Elodea (an aquatic plant)

- 4 capped test tubes containing 30 ml of phenol red solution each

- beakers

- lamp

- drinking straw s

- aluminum foil

- test tube rack

1. Obtain and number four test tubes of phenol red either 1, 2, 3, or 4 using a wax pencil . Warning: Hold test tubes by their sides and not by their caps. The test tube caps are the “ slip cap ” type and consequently the glass tube can fall out if not held by hand.

2. Uncap one of the tube s and pour its contents into a small beaker. B low into this liquid using a drinking straw until its color changes to a yellow - pale orange. Return the liquid back into this tube and recap . Repeat with the other 3 test tubes.

3. Stuff a large piece of fresh Elodea into Tubes 2 and 4. Fresh Elodea are a brighter green and bushier than older Elodea .

4. Cover Tubes 3 and 4 with aluminum foil so that no light can enter.

5. Place entire rack containing four tubes under a bright lamp , positioning the neck of t he lamp so that it gives maximum exposure . Light should only penetrate the uncovered tubes (1 and 2).

6. Be sure each tube is tightly capped.

7. Observe tubes 1 and 2 throughout the lab period . After 9 0 minutes have passed , remove the aluminum foil from 3 and 4 and observe.

8. Record your observations in the table below.

9. When everyone in your group has recorded the results, clean up by pouring the liquid from the tubes into the waste disposal container and putting the Elodea into the red biohazard waste cans. R ub the wax pencil markings off with a paper towel, rinse the tubes and leave them by the sink. Thanks!
