Matthias Schleiden, a botanist, and Theodor Schwann, a zoologist, studied a wide number of organisms and, together, wrote what we know today as Cell Theory: The cell is the basic unit of life and all living organisms consist of one or more cells.
Of what type of reasoning is this an example?
Inductive reasoning
Julie loved hummingbirds and all summer long she would hang nectar feeders outside her windows and fill them with sugar water to attract those beautiful little flying jewels to her yard. She was always sad when winter came and her beloved hummingbirds would leave for warmer climes. Julie was feeling especially discouraged one cold and bleak winter day in January but comforted herself by thinking, “only three more months and my little friends will return bringing joy back into to my life!”
Of what type of reasoning is this an example?
Deductive reasoning
In class you were shown a diagram representing the process of science; this diagram had three small circles around a large central circle, and there were arrows going back and forth between all the circles. Each of the following are important components of the process of science; which one of these is the focus of the process of science, as indicated by its placement in the large circle at the center?
Forming and testing hypothesis
We discussed an experiment wherein we were testing our hypothesis that drinking caffeinated coffee prevents daily memory decline. In this study, memory decline was measured using a memory test.
What was the control group?
A group of randomly placed participants who were not given coffee
A group of women over age 65
A group of randomly placed participants who were given caffeinated coffee
A group of men over age 65
A group of young adults (average age of 25)
A group of randomly placed participants who were given decaffeinated coffee
A group of randomly placed participants who were given decaffeinated coffee
We discussed an experiment wherein we were testing our hypothesis that drinking caffeinated coffee prevents daily memory decline. In this study, memory decline was measured using a memory test.
What was the independent variable?
The type of coffee
We discussed an experiment wherein we were testing our hypothesis that drinking caffeinated coffee prevents daily memory decline. In this study, memory decline was measured using a memory test.
What was the dependent variable?
The score on the memory test
We discussed an experiment wherein we were testing our hypothesis that drinking caffeinated coffee prevents daily memory decline. In this study, memory decline was measured using a memory test.
What was a standardized variable?
The age of the participants
Which element of this graph represents the dependent variable?
Y-axis

Some people claim that fire is alive. Are they wrong?
Fire is not alive. To be classified as living, a thing must show all seven of the characteristics of life
Fire is not alive. To be classified as living, a thing must show at least 5 of the seven characteristics of life
Scientists do accept fire as living because it meets the standard of showing at least 4 of the seven characteristics of life
Fire is not alive. To be classified as living, a thing must show at least 6 of the seven characteristics of life
Fire is not alive. To be classified as living, a thing must show all seven of the characteristics of life
