|
What is a nucleotide?

What is the purpose of a ribosome?
To synthesizes proteins.
|
What is a Heterozygote
Possessing different alleles of a certain gene
|
What is a population?
A group of organisms of the same species populating a given area
|
What is the belief that evolution occurs suddenly?
Punctuated equilibrium.
|
What is a mutation?
A change in the nucleotide base sequence of a gene or DNA molecule.
|
What does the chloroplast do?
Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.
|
What is a Phenotype
An observable characteristic
|
What are the three kinds of symbiotic relationships?
Mutualism, Commensalism, and Parasitism

What is Meiosis
Type of cell division that gives rise to haploid gametes.
|
What is a carrying capacity?
Largest number of individuals of a population that an environment can support

Is a trait or an organ that has a similar function in two or more unrelated organisms.
