Exam 1: An Introduction to Life on Earth

Consider the observation that people taking Drug X for headaches also seem to have low blood pressure. Design a simple experiment based on this observation, and include a hypothesis statement and your actual experimental design for the study.

The main difference between an autotroph and a heterotroph is A) how they reproduce. B) their ability to move. C) how they respond to stimuli. D) how they obtain energy.

Science cannot answer certain faith- based questions because

Which of the following statements about the Bacteria and Eukarya domains is TRUE?

A mutation is a

Scientific inquiry is based on

All of the following are examples of adaptations EXCEPT

A mutation can be the cause for

Which of the following is TRUE regarding faith- based beliefs and scientific theories?

Which is the correct sequence of increasing organization?

Scientific theories are the same in any part of the world (meaning they do not vary by location).

Suppose that a meteorite crashes into Earth and a sample of it is taken to a local research lab for analysis. Embedded several inches within the rocky structure, a microscopic cluster of dormant, spore- like structures is found. The scientists culture some of this material in a standard microbiological nutrient broth, and they are surprised to find many single- celled "organisms" moving around, growing, and reproducing in the broth. The "organisms" behave the same in both daylight and dark conditions, do not require oxygen, and thrive under a wi range of temperatures and pH levels. They stop moving, growing, and reproducing, however, when fewer nutri available in the medium. In this scenario, the "organisms" most closely resemble a(n)

Describe at least two cellular- level differences between a photosynthetic prokaryote and a plant.

All of the following are important to the theory of evolution EXCEPT

In a word, "evolution" means

Evolution is based on adaptations that aid in the survival and reproduction of a species. List three different adaptations.

Adaptations include all of the following EXCEPT

A scientific explanation that is conditional and requires more investigation is called a(n)

Which of these would be an example of a NON- scientific study?
