Course Introduction
Environmental Biology Exam Preparation Guide
Environmental Biology examines the interactions between living organisms and their environment, focusing on ecological principles, biodiversity, and the impact of human activities on natural systems. Through exploring topics such as energy flow, nutrient cycling, population dynamics, and conservation biology, students will gain a comprehensive understanding of how environmental factors shape biological communities and influence ecosystem health. The course also highlights current environmental challenges, including climate change, pollution, and habitat destruction, and emphasizes solutions for sustainability and environmental stewardship.

Sample Questions
Q1) Numerous studies have shown that the more often a person performs a workout routine that increases heart rate,the better their overall heart health is.You have two groups of individuals who are willing to participate in a heart-health experiment.Fifty are non-smoking males,ages 18 to 22,who work out three times per week.Fifty are non-smoking males,ages 18 to 22,who do not work out on a regular basis.In the experiment,they will step up and down on an 8-inch-high cinder block 120 times/minute for 3 minutes.Researchers will examine their heart rate before starting,immediately after they finish,and every minute after finishing until their heart rate returns to their original rate.Two common measures of heart health are the percentage increase in heart rate caused by exercise and the time the heart rate takes to return to the base rate.Based on these parameters,what is your hypothesis regarding the heart health and test performance of the two groups?
Answer: The non-exercising group will have a greater increase in heart rate and a longer recovery time than the exercising group,indicating an overall lower level of heart health in the non-exercising group.
Q2) What is the dependent variable in this study?
Answer: The dependent variable is attention span.
