evolution occurs at the _ level.

a. individual
b. population
c. community
d. ecosystem

Explanation:

• Question 9: Structural homology refers to the similarity in the structure of organs (like kidneys, stomach, heart, and lungs) across different species (frogs, birds, snakes, rodents). Genetic correlation is about the relationship between genetic traits. Inheritance of acquired characteristics is an outdated theory. Developmental homology is about similarities in embryonic development, not the structure of adult organs.
• Question 10: Evolution is a change in the genetic composition of a population over time. An individual does not evolve (its genes don't change in a way that represents evolution during its lifetime). A community is a group of different populations, and an ecosystem includes communities and their physical environment. Evolution occurs at the population level as it's about changes in allele frequencies within a group of interbreeding organisms.

Answer:

• Question 9: C. structural homology
• Question 10: B. Population
