Cells
What is the basic unit of life
What is a genotype?
Genetic makeup of an organism.
What is natural selection?
Process by which organisms with favorable traits survive and reproduce.
What is an ecosystem?
Community of organisms interacting with each other and the environment.
What are the reactants for photosynthesis?

What is the difference between homozygous and heterozygous?
Homozygous has two identical alleles, heterozygous has two different alleles
Name one evidence that supports the theory of evolution.
Fossil records, DNA similarities, homologous structures

What are the three main parts of a eukaryotic cell?
Cell membrane, nucleus, cytoplasm
What is the function of DNA?
Stores genetic information
What is the difference between convergent and divergent evolution?
Convergent evolution: unrelated species develop similar traits, Divergent evolution: species with common ancestor develop different traits
What is the greenhouse effect?
Trapping of heat in Earth's atmosphere
What are the three steps of cellular respiration?
Glycolysis, Krebs Cycle, Electron Transport Chain
What is the nucleus?
Contains DNA, controls cell activities.
What is the difference between dominant and recessive genes?
Dominant genes are expressed, recessive genes are hidden
What is the role of mutations in evoltion?
Introduces genetic variation, drives evolution
What is a carrying capacity?
The maximum amount of individuals in a population that an environment can support.
Light Independent (Calvin Cycle)
