Exam 1: Science As a Way of Learning: a Guide to the Natural World

Tissues are grouped together in functional units called:

Evolution allows us to explain:

The scientist who demonstrated that the Earth moves around the sun was ________.

The difference between a theory and a hypothesis is that a:

The role of a control in an experiment is to:

A set of disciplines that focuses on varying aspects of the living world falls under the category of ________.

Match the following. A) population B) cell C) biosphere D) molecule E) ecosystem -Members of the same species living in the same area

It doesn't matter whether a hypothesis is correct when it is first stated.

Match the following. A) population B) cell C) biosphere D) molecule E) ecosystem -The building blocks of organelles

What is meant by the statement "science is measurement"?

Organelles are:

A unifying principle of biology states that there is a gradual modification of populations of living things over time that sometimes results in new species. This principle is called ________.

Which scientist disproved the theory of spontaneous generation?

When Pasteur tested the hypothesis of spontaneous generation, he compared the ability of a sterilized growth medium (meat broth) to produce a population of bacteria in two different types of flasks. One had a simple neck open to the outside, and the other had a "goose neck" bend that also was open to the environment. Pasteur expected that bacteria would appear in the flask with the standard neck. In this experiment, the standard neck flask served as a/an:

Discuss why it is important that the public be knowledgeable about science.

Imagine you're a biology instructor lecturing to a group of students interested in ecology, the branch of biology that studies interactions between organisms and their environments. The students complain bitterly that they're not interested in atoms and molecules because these are irrelevant to their interests. As a responsible instructor aiming to provide a complete and meaningful education, you would state:

A tree in your backyard is home to robins, squirrels, beetles, and lichens. Together all these organisms compose a/an:

The liver releases glucose into the bloodstream if you don't eat for a long time. This represents an example of a characteristic possessed by all living things. Which is it?
