Week 6 Homework

The information provided by fossils about the Earth's history.

• Fossil Record
• Extinction
• Evolution
• Genetic Variation

What would most likely be the cause for a specific species to go extinct?

• They develop aggressive behaviors with fights that led to death

• They were captured and put into captivity and did not survive

• All failed to adapt to the changes in their environment

• They changed their physical characteristics and evolved into a new species.

When dating fossils based on their location the newer the fossil the

• deeper in the sediment

• higher in the sediment

A population of birds has many small variations among the individuals in the population. Variation in beak size among these birds would affect their survival the most if

• size of nesting areas decrease

• weather in the environment changes

• type of food available in the area changes

• amount of water available in the area decreases

If a new predator is introduced to an environment, which mice would most likely survive?

• mice that stand out in their environment

• mice with a low tolerance for lack of food

• fast mice that blend into their environment

• slow mice with a high tolerance for lack of food

Where humans have bred organisms together based on traits we like.

• Evolution
• Natural Selection
• Extinction 
• Artificial Selection

Why did the population of peppered moths in England change from light to dark after the Industrial Revolution?

• Light moths were easy to see against sooty trees and were eaten
• Light moths were killed by soot
• The birds that ate the dark moths were killed by soot
• Dark moths were produced by industrial processes

What is it called when better adapted organisms survive to pass traits along to their offspring.

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

What is the advantage of having different shaped beaks?

• To look different from other species.
• To be able to eat different types of food.
• To fly faster.
• To confuse scientists. 

Evolution means...

• Change over time in a population.
• That everything is the same.
• That organisms never change.
• Negative traits are acquired in populations.
