• Molecule

• Protein

Complex molecules that are responsible for traits

• Protein

• Sugar

• Genes

• H2O

The way in which traits are shared in the population

• Predominant

• Resistance

• Distribution

• Heritable

The ability to be unaffected by something usually harmful

• Resistance

• Mutation

• Natural Selection

• Adaptation

Changes in a species over generations, due to changes in the environment

• Distribution

• Mutation

• Adaptation

• Resistance

Process in which traits become more/less common due to some traits making it more likely for individuals to survive and reproduce

• Natural Selection

• Mutation

• Distribution

• Adaptation

A random and permanent change to a gene

• Protein

• Gene

• Natural Selection

• Mutation

When nearly all individuals in a population have a certain trait

• Predominant

• Resistance

• Adaptation

• Mutation

What needs to be true for adaptation to occur?

• A trait exists in a population

• Organism's ability to survive and reproduce are increased

• Trait is heritable

• The trait needs to be predominant in a population

Which statement(s) are true about mutations, Mutations....

• are not necessary for adaptation to occur

• can lead to a new predominant trait in a population

• only happen when the environment changes

• are very common
