physiological adaptations to predict which populations are likely to survive in a particular environment

SPI 0807.5.3 Analyze data on levels of variation within a population to make predictions about survival under particular environmental conditions.

I can: Identify an adaptation as structural, behavioral, or

physiological. Explain how an adaptation helps an organism survive in a

particular environment.
