Unit 5: Urbanization: Lesson 1& 2 Flashcard

Front

What are dependent variables?

Back

Dependent variables are the outcomes measured in an experiment that are influenced by independent variables.

Front

Define phenotypic variation.

Back

Phenotypic variation is the observable differences in traits among individuals of a species.

Front

How do certain species adapt to urban environments?

Back

Species adapt by changing their diet; strategic actions include preserving natural food sources and reducing waste.

Front

What is phenotypic expression?

Back

Phenotypic expression is the manifestation of an organism's genotype in its observable traits.

Front

Explain what is meant by physical variations.

Back

Physical variations are the differences in physical traits among individuals of the same species.

Front

What is urbanization?

Back

Urbanization is the process by which rural areas become urbanized as a result of population growth and migration.

Front

What are independent variables?

Back

Independent variables are the factors that researchers manipulate during an experiment.

Front

What is the significance of preserving natural habitats in urban areas?

Back

Preserving natural habitats supports biodiversity and helps species adapt to urban environments.

Front

What role does diet play in species adaptation?

Back

Diet changes can help species survive in urban environments by utilizing available food resources.

Front

What is the relationship between genotype and phenotype?

Back

Genotype refers to the genetic makeup of an organism, while phenotype is the observable expression of that genotype.
