amount of material being measured, which of the following is an example of an intensive
property?

B. Density
C. Volume
D. Length

hypothesis that air contains bread mold spores?
A. Seal slices of bread in a container to mineralize air contact
B. Place slices of bread in a refrigerated environment
C. Add ingredients to the bread recipe that will slow mold growth
D. Expose a different mold-supporting medium to air

following statements is correct regarding the organisms in which photosynthesis and

forms

scientists' contention that it exists?
A. It serves as a working hypothesis to explain real observations in the universe
B. A basic scientific principle is to consider everything possible until proven otherwise
