HELP PLEASE PLEASE GIVE RIGHT ANSWERS *Picture is for Question 2*

1. A firefly relies on a protein called luciferase to produce light. Luciferase is an enzyme that catalyzes a light-producing reaction in a special organ in the insect's abdomen. Name three organelles that you expect to be abundant in the firefly cells based on the organelle function AND why?

2. Two eggs are soaked in vinegar to remove the shell and expose the thin semipermeable membrane that surrounds an egg. One egg is placed in a hypotonic solution (distilled water) and the other is placed in a hypertonic solution (highly concentrated salt water). (1) What passive transport process will occur? (2) Describe the movement of molecules that will occur with each of these eggs.

3. Sensors on a spider's legs feel the vibrations of a trapped insect and relay the information to the spider's brain through nerve electrical signals. For nerve cells to maintain these electrical potentials, sodium must be removed from the cell and potassium must be moved into the cell. Describe why this process is a form of active transport and what is required for active transport to occur?
