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

WHAT IS ADAPTIVE ADVANTAGE?

Gives organisms a greater chance of surviving because of characteristics that allow them to be more successful than other organisms

HOW ARE XY GAMETES AND XX GAMETES ALIKE? DIFFERENT?

Alike both gametes can develop into adult humans

Different: XX gametes become Females

XY gametes become Males

WHAT DOES THE THEORY OF DESCENT WITH MODIFICATION STATE?

More recent species are changed descendants of earlier species

HOW 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.

WHAT IS AN INNATE BEHAVIOR?

One that is inherited and does not have to be learned. It is present at birth.
