____________ is the ability of an organism to maintain a stable internal balanced environment.
What is homeostasis?
______ is the most direct source of energy that a CELL USES to carry out life processes.
What is ATP?
Respiration (breathing) involves the exchange of these two gasses
What is oxygen and carbon dioxide?
The ________ variable is the thing that changes because of the independent variable.
What is the dependent variable?
This form of reproduction is beneficial because it increases variation among its offspring.
What is sexual reproduction?
_________ is the process of storing the energy from the sun in the chemical bonds of glucose (organic molecule).
What is photosynthesis?
