GENE, CHROMOSOME, REPLICATE, DIVERSITY, MUTATION, EVOLUTION, SCIENTIFIC THEORY, ADAPTATION, HYPOTHESIS, HEREDITY the passing of traits from parents to offspring Heredity

GENE, CHROMOSOME, REPLICATE, DIVERSITY, MUTATION, EVOLUTION, SCIENTIFIC THEORY, ADAPTATION, HYPOTHESIS, HEREDITY generally accepted and tested scientific explanation Scientific Theory

GENE, CHROMOSOME, REPLICATE, DIVERSITY, MUTATION, EVOLUTION, SCIENTIFIC THEORY, ADAPTATION, HYPOTHESIS, HEREDITY change in a gene mutation

GENE, CHROMOSOME, REPLICATE, DIVERSITY, MUTATION, EVOLUTION, SCIENTIFIC THEORY, ADAPTATION, HYPOTHESIS, HEREDITY information about a trait that a parent passes to its offspring gene

GENE, CHROMOSOME, REPLICATE, DIVERSITY, MUTATION, EVOLUTION, SCIENTIFIC THEORY, ADAPTATION, HYPOTHESIS, HEREDITY change that makes an organism better able to survive in its environment Adaptation

A(n) _________________________ ________ is a body part that seems to be useless. Vestigial structure

Sex cells are formed by the process of ________________. Meiosis

A(n) _____________________ results in the death of an organism. Lethal mutation

______________ are body parts that are similar in related organisms. Homologous structures

The genetic changes that are passed on in a population occur in an organism’s______________. Gametes

W HAT IS ADAPTIVE ADVANTAGE ? Gives organisms a greater chance of surviving because of characteristics that allow them to be more successful than other organisms

H OW ARE XY GAMETES AND XX GAMETES ALIKE ? D IFFERENT ? Alike both gametes can develop into adult humans Different: XX gametes become Females XY gametes become Males

W HAT DOES THE THEORY OF DESCENT WITH MODIFICATION STATE ? More recent species are changed descendants of earlier species

H OW CAN A POPULATION ’ S DIVERSITY HELP IT SURVIVE A SUDDEN CHANGE IN ITS ENVIRONMENT ? Diversity enables some individuals in a population to survive sudden environmental changes because they have characteristics that enable them to adjust to the changes.

W HAT IS AN INNATE BEHAVIOR ? One that is inherited and does not have to be learned. It is present at birth.
