Anything that occupies space and has mass.
What is matter?
100
Large molecules that make up living organisms, such as proteins, carbohydrates, lipids, and nucleic acids.
What is a macromolecule?
100
Simple cells that do not have a nucleus; this type of cell is found in bacteria.
What is prokaryotic cells?
100
The movement of materials into and out of cells.
What is cellular transport?
200
In an experiment, this is the group that does not receive any treatment.
What is a control group?
200
A type of chemical bond where ions are formed by either gaining or losing electrons.
What is ionic bonding?
200
The monomer of carbohydrates, which also means "simple sugar".
What is a monosaccharide?
200
The control center of a cell.
What is nucleus?
200
Processes such as osmosis and diffusion that do not require energy from the cell.
What is passive transport?
300
A substance given to a control group that has no effect on the experiment, but is used to eliminate bias.
What is a placebo?
300
Water forms weak bonds with other water molecules by this type of bond.
What is hydrogen bond?
300
This macromolecule provides long-term energy storage for animals.
What is lipids?
300
Cellular structure that surrounds plant cells and gives them support and protection.
What is cell wall?
300
Having a higher solute concentration outside the cell and causing the cell to shrink.
What is hypertonic?
400
There are two types of variables that are important in an experiment. Fill in the following sentence, "____________depends on ____________."
Dependent variable depends on independent variable?
400
Compounds that produces hydroxide ions in solutions.
What is a base?
400
The general structure of this macromolecule consists of an amino group and a carboxyl group.
What is proteins?
400
A large organelle in most plant cells that is filled mostly with water and helps to give the cell structural support.
What is vacuole?
400
During glycolysis, glucose is broken down into pyruvic acid, and two molecules of ATP are formed. If no oxygen is present, what will happen next.
What is lactic acid fermentation?
500
In order for an experiment to be scientifically valid, it must give meaningful results. To get these results, three things must be carefully done.
What is designed, controlled, & performed?
500
This element is important because it has four valence electrons and can form single, double, and triple covalent bonds with other elements.
What is carbon?
500
This macromolecule is responsible for heredity and the storing & sending of genetic information.
What is DNA?
500
This organelle helps to make proteins and may be free-floating or attached to the endoplasmic reticulum.
What is ribosome?
500
This stage of photosynthesis does not require light; Carbon dioxide and hydrogen ions combine to form glucose.
What is Calvin cycle?
