The white feathers of a snowy owl allow it to blend in with its environment during the winter months. This is an example of a(n) ________________.

• species

• environmental change

• adaptation

• variation

Definition: fitness

• ability to survive and reproduce in a specific environment
• organisms with traits well suited to their environment survive and reproduce at a greater rate
• a growing population causes a scarcity of resources
• differences in the DNA sequence

Read the paragraph and decide which of the 4 principles of natural selection is described: variation, overproduction (competition), adaptation, descent with modification. Each color represents a different principle. For question 9, which sentence represents variation?

1. Bacteria have many traits, some have antibiotic resistance (They don't die when they you take antibiotics) some are killed by antibiotics right away. 2. Bacteria reproduce rapidly and make a lot of themselves quickly. When bacteria are initially exposed to an antibiotic, some die off right away because they have no special way to stop antibiotics. 3. Through mutation and selection, bacteria can develop defense mechanisms against antibiotics. For example, some bacteria have developed “pumps” that can remove an antibiotic before it reaches its target. 4. This special adaptation will make them able to survive and pass on this feature to future generations that will also have the special "pump".
