What happened that allowed cells to be studied?
Cells increased in size.
Scientists began to work together.
Scientists became smarter.
The microscope was invented and improved.
What is a benefit of the development of the cell theory?
Cells have made microscopes improve.
There are less biologists today.
There is more diseases on Earth now.
Scientists now know much more about cells and bacteria, which allows them to better treat disease.

A student wanted to know if guinea pigs prefer living in the dark. The student placed one guinea pig in a cage with half the cage covered to simulate night time and half uncovered to simulate daylight and then watched to see if the guinea pig spent most of his time on the dark side or light side. What is wrong with this experiment?
The student should have at least three cages with a guinea pig inside to test the environmental conditions.
The student should take the guinea pig out at least twice a day so it can have company.
The student should add another guinea pig and watch what both of them do.
The student should also track how much food the guinea pig eats.

What does "cells come from other cells" mean?
When cells move they need another cell to go with it.
Cells can be created out of thin air.
Cells are only created by other cells.
Animal cells come from plant cells.
The cell theory was not complete until Rudolph Virchow discovered that...
cells are alive.
there are two types of cells (prokaryotic/eukaryotic)
all cells come from preexisting cells.
cells are the basic building blocks of life.
What is a dependent variable?
an experimental subject that is purposefully not tested
the variable that responds to the manipulated variable
knowledge acquired by observation or experimentation
a method of testing a hypothesis using controlled conditions and clearly defined variables
What is an independent variable?
the variable that is manipulated to test a hypothesis
a theory that is proven with evidence, and widely accepted as true
the variable that responds to the manipulated variable
the variable that stays the same
What is a constant variable?
Responds to the independent variable
Directly tested (and changed) by the scientist
Intentionally kept the same by the scientist
Intentionally omitted by the scientist

Scientists wanted to study the effect of different flower pollen sources on the lifespan of honey bees. They studied six different groups, each with access to a combination of two different flower types. All six groups were treated the same except for type of flower source. The table below shows the average lifespan for each control group in hours.
Which of the following statements are supported by the data?
Bees will exhibit the longest lifespan when feeding on sunflowers, rather than any flower whether in the study or not.
When paired with tulips, daisies will result in the shortest bee lifespan as compared to tiger lilies or sunflowers
Combining all five flowers will lead to the longest lifespan for the bees
None of these
Mr. Krabbs wants to make Bikini Bottoms a nicer place to live. He has created a new sauce that he thinks will reduce the production of body gas associated with eating crabby patties from the Krusty Krab. He recruits 100 customers with a history of gas problems. He has 50 of them (Group A) eat crabby patties with the new sauce. The other 50 (Group B) eat crabby patties with sauce that looks just like new sauce but is really just mixture of mayonnaise and food coloring. Both groups were told that they were getting the sauce that would reduce gas production. Two hours after eating the crabby patties, 30 customers in group A reported having fewer gas problems and 8 customers in group B reported having fewer gas problems.
Which people are in the control group?
Group A
Group B
Both Groups
There is no control group

Continue to accept the explanation that does not fit the evidence.
Ignore the new evidence that goes against the explaination.
Choose all of the tools used for measuring volume.
