Unit 1
Types of bias that can negatively affect science are selective sampling, selective reporting, and/or industry sponsorship.
What types of bias can negatively affect science?
A cell is the basic structural unit of all living organisms
What is a cell?
A machine-like molecule that can carry out specific functions in a cell.
What is a protein?
A collection of fossils placed in chronological order.
What is the fossil record?
Behaviors or activities performed by an organism that increase its fitness.
What is a behavioral adaptation?
Graphs can express more information within a smaller area than text can. Graphs make it easier to identify trends in data.
What are the benefits to using graphs in science?
All living things are made up of one or more cells, they come from previously living cells, and cells carry out the functions needed to support life.
What are the three basic statements of the cell theory?
What does dominant mean?
The extinction of a large number of species in a relatively short period of time.
What is a mass extinction?
They reduce their body temperature and their body functions slow down.
During hibernation, how does an animal’s body change?
A bar graph shows data using rectangles that are equally spaced apart and shows relationships between sets of data. A histogram compares data ranges that contains bars next to each other instead of spaced apart.
What are the differences between a bar graph and a histogram?
An amoeba is a unicellular organism.
What type of a cell is an amoeba?
A molecule that reflects only certain colors of light and absorbs the rest.
What is a pigment?
Characteristics that were not present in a common ancestor.
What is a derived trait?
Anatomical features that increase an organism's fitness.
What are physical adaptations?
