Scientific Method
A scientific investigation that is performed under controlled conditions.
What is an experiment?
This element is required for all biomolecules.
What is carbon?
It is called this, because many substances dissolve in water.
What is the universal solvent?
Powerhouse of the cell.
What is a mitochondria?
Molecules continue to move, but the overall concentration remains the same.
What is equilibrium?
The thing you change.
What is the manipulated (independent) variable?
This marcomolecule is a central energy source in organisms & cellular support.
What are carbohydrates?
Property of water where other water molecules are attracted to each other.
What is cohesion?
What is the golgi apparatus?
Movement of particles from an area of high concentration to an area of low concentration.
What is diffusion?
An explanation or answer that can be tested.
What is a hypothesis?
This macromolecule transmits and stores genetic information.
What are nucleic acids?
Property of water where water molecules form hydrogen bonds with other surfaces.
What is adhesion?
Control center of the cell.
What is the nucleus?
Uses transport proteins to move ions and small molecules across the plasma membrane.
What is facilitated diffusion?
Numerical data gathered from obervations.
What is quantitative data?
Molecules made mostly of carbon and hydrogen that make up the fats, oils, and waxes.
What are lipids?
Substance dissolved in a solvent.
What is solute?
Specialized plant organelle responsible for photosynthesis.
What is a chloroplast?
Diffusion of water across a selectively permeable membrane.
What is osmosis?
Combines observations and experiments into a general explanation for a scientific phenomenon.
What is a theory?
Enzymes are a part of this class of macromolecules.
What are proteins?
Substances that release H+ ions when dissolved in water.
What are acids?
Helps cells maintain their shape and internal organization.
What is a cytoskeleton?
When net movement of water is out of the cell & causes wilting in plants.
What is a hypertonic solution?
