Chapter 1: Introduction to Biology
Art Connection Questions
1. Figure 1.8

A. Tissues exist within organs which exist within organ systems.
B. Communities exist within populations which exist within ecosystems.
C. Organelles exist within cells which exist within tissues.
, D. Communities exist within ecosystems which exist in the biosphere.

B. Communities exist within populations which exist within ecosystems.
2. Figure 1.18
In the example below, the scientific method is used to solve an everyday problem. Which part in
the example below is the hypothesis? Which is the prediction? Based on the results of the
experiment, is the hypothesis supported? If it is not supported, propose some alternative
hypotheses.
1. My toaster doesn’t toast my bread.
2. Why doesn’t my toaster work?
3. There is something wrong with the electrical outlet.
4. If something is wrong with the outlet, my coffeemaker also won’t work when plugged into it.
5. I plug my coffeemaker into the outlet.
6. My coffeemaker works.
Answer
The hypothesis is #3 (there is something wrong with the electrical outlet), and the prediction is
#4 (if something is wrong with the outlet, then the coffeemaker also won’t work when plugged
into the outlet). The original hypothesis is not supported, as the coffee maker works when
plugged into the outlet. Alternative hypotheses may include (1) the toaster might be broken or (2)
the toaster wasn’t turned on
