6. A type of cell division that results in four daughter cells.
8. your body's command center
9. nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again.
11. is a molecule that contains the instructions or recipe that directs the cells to make a protein using its natural machinery
13. when the severity of disturbance is insufficient to remove all the existing vegetation and soil from a site
17. is defined as movement of a solute from a region of high electrochemical potential on one side of the cell membrane to a region of lower electrochemical potential on the opposite side.
18. Delivers oxygen and nutrients to cells and takes away wastes.
19. animals that get their energy by eating plants or other animals.
22. A form of viral reproduction involving the fusion of the nucleic acid of a bacteriophage with that of a host, followed by proliferation of the resulting prophage.
