This is an educated guess that can be tested.
What is a hypothesis?
This macromolecule is the main source of energy for the body.
What is a carbohydrate?
This organelle is the control center of the cell.
What is the nucleus?
DNA is shaped like this.
What is a double helix?
The process by which a cell divides into two identical daughter cells.
What is mitosis?
This variable is intentionally changed in an experiment.
What is the independent variable?
The monomer of a protein.
What is an amino acid?
The powerhouse of the cell, responsible for energy production.
What is the mitochondrion?
The base that pairs with adenine (A) in DNA.
What is thymine (T)?
The phase of the cell cycle where the cell spends most of its time growing and preparing for division.
What is interphase?
A group in an experiment that does not receive treatment and is used for comparison.
What is the control group?
Enzymes speed up reactions by lowering this.
What is activation energy?
These cells do not have a nucleus.
What are prokaryotic cells?
The three parts of a nucleotide.
What are a sugar, phosphate, and nitrogen base?
The stage of mitosis where chromosomes line up in the center of the cell.
What is metaphase?
The factor that is measured as a result of changes in an experiment.
What is the dependent variable?
The site on an enzyme where the substrate binds.
What is the active site?
This organelle is responsible for making proteins.
What are ribosomes?
These molecules make up the backbone of the DNA strand.
What are sugar and phosphate?
The final phase of mitosis where the nuclear envelope starts to reform.
What is telophase?
The term for all variables that are kept the same in an experiment to ensure accurate results.
What are control variables?
This macromolecule stores genetic information in the body.
What is a nucleic acid?
This organelle helps transport materials throughout the cell and can be rough or smooth.
What is the endoplasmic reticulum?
The rules that determine how nitrogen bases pair together in DNA.
What are the base-pairing rules?
A disease that results from uncontrolled cell division.
What is cancer?
