- Intracellular Structures (Organelles)
- Cells
- Tissues
- Organs
- Organ Systems
- Organisms

ATP
Adenosine Triphosphate
The chemical processes involved in the production of ATP, the primary organic compound used for energy
Metabolism
Plants - _________
Animals - ________
Plants - Photosynthesis
Animals - Cellular Respiration
If there is __________, there is a response
Stimulus
Internal Balance
Homeostasis
The ability of an organism to maintain a steady internal environment that is optimal for physiological processes, despite the fluctuating external environment.
Homeostasis
The way life maintains homeostasis
Feedback Mechanism
2 Types of Feedback Mechanism
Negative Feedback
Positive Feedback
Perform to induce/decrease the initial change. It is the system’s way to go back.
Negative Feedback
Not common way of Feedback Mechanism. It will further enhance the system which will then go back to the regular/optimal balance.
Positive Feedback
Type of feedback where it goes more is more
Positive Feedback
The idea where life comes from life
Reproduction
Heritable program within DNA directs __________
Organismal pattern of growth
All things needed to change and develop are encoded in the ________
DNA/Deoxyribonucleic Acid
True or False: All changes in DNA are inheritable
False
A heritable change that occurs within an organism, allowing for better adaptation within its environment.
Evolutionary Adaptation
Basic unit which makes up micro and macro molecules
Atoms
Another term for micro molecules
Micromers
It makes up the DNA (Polymer)
Micro and Macro molecules
4 Types of Biological Macromolecules
Nucleic Acids
Proteins
Lipids
Carbohydrates
