An animal is a living organism that feeds on organ matter.

DNA stores a code that carries the instructions for making proteins.

Genes are the instruction for inherited traits?

Invertebrates are living organism without a backbone, like a slug.

The structure of DNA is a double helix, which is shaped like a twisted ladder.

Alleles are the alternative forms of a gene that governs a characteristic, such as hair color.

DNA is made of subunits called nucleotide.

Phenotype are organism's appearance or other detectable characteristic.

Animal bodies have two basic type of symmetry?

A nucleotide consists of a sugar, a phospate, and a base.

Genotype are the attire genetic makeup of an organism;also the combination of genes for one or more specific traits.

A consumer is an organism that eats other organisms or organic matter.

Proteins are found throughout cells and cause most of the differences that you can see among organisms.

Genetic variation are the differences in the sets of alleles between individuals in a population.
