Why do embryologist study embryos?

• to see if they are related
• to understand adaptations
• to determine the age
• to learn what parents are vestigial

What is one reason that strawberries are surviving in the winter season?

• they have larger leaves
• they have genetic variations allowing them to be resistant to cold
• they reproduce more
• the color is dark

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
• Hardey-Weinberg equilibrium within a population

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures
