7ABCDE: Common Ancestry & Evolution Review

Genetic differences between organisms of the same species are:

• variation

• adaptation

• behavior

• environment

The gradual change in species over time is...

• Evolution

• Nucleotide 

• Adaptation

• Natural Selection

Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring? 

• Evolution 
• Variation 
• Adaptation
• Natural Selection 

Predict which moth would increase in population

• light 
• dark

Do organisms "decide" to evolve and change?

• Yes, they know they need to change to survive 
• No, they change because of natural selection

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

What word describes a trait that helps an organism survive in its environment?

• natural selection

• mutation

• camouflage

• adaptation

The more genetic variation a population has,

the more likely it is for some individuals to

• evolve

• migrate

• survive

• mutate

Mutations are important because they bring about

• death of the organism in which they develop

• genetic variation needed for a population to evolve

• benefits for the individual, not for the population

• changes in genotype, but not phenotype

Why do frogs and other organism reproduce so many eggs or offspring?

• so that their babies can have friends to play with
• the more offspring the more likely the offspring will survive
• the more offspring the less likely offspring will survive 
• the more offspring the less competition
