structures that are similar in function, but differ in structure

traits that help an organism survive

the color, markings, or body shape that helps to hide an animal or plant in its surroundings

the study of gene structure and function

the seasonal movement of animals from one region to another

an adaptation in which one species looks like another species

process in which living things with beneficial traits survive longer and produce more offspring so their traits increase in a population over time

the study of the development of embryos

change in the inherited traits of organisms over time

inherited structure that is no longer used but is still present in a modern organism that inherited it from an ancestor that used the structure

a state in which an animal’s body processes are slower than usual, and its body temperature falls

the study of similarities and differences of body parts of different species

difference in traits caused by mutations

body parts that are similar in structure but differ in function
