What is the Mitochondrion?
The physical shape of a DNA molecule, resembling a twisted ladder.
What is a double helix?
The type of cell division that results in two identical daughter cells for growth and repair.
What is mitosis?
An organism that makes its own food using sunlight or chemicals, forming the base of every food chain.
What is a producer?

What is mutualism?

What is osmosis?
The stage of cellular respiration that takes place in the cytoplasm and breaks glucose down into pyruvate without needing oxygen.
A permanent change in the chemical sequence of an organism's DNA.
What is a mutation?
Specialized cell division that creates four genetically diverse haploid gametes.
What is meiosis?
A species that has an unusually large effect on its ecosystem; if removed, the entire ecosystem web can collapse.
What is a keystone species?
Biological catalysts-usually proteins-that speed up chemical reactions by lowering the activation energy required.
What is an enzyme?
