Many animals who live where it snows have fur. Explain how white fur makes surviving in the snowy environment easier.

• Orange fur make them easier to spot.

• White fur allows them to better blend in with their habitat.

• The color of fur doesn't effect an animals chance of survival.

• White fur is cooler then other fur colors.

Explain how the fossil record is evidence for the scientific theory of evolution.

• It proves what future species of animals will look like in the future.

• It shows that extinct animal have become a fossil through selection.

• It shows that extinct species share similarities with current species.

• It allows scientist to compare fossils from the past to undiscovered fossils.

The pictures are from different types of animals. What can be said about them that is true?

• They all have different bones, which implies that they all share a different ancestor.

• They all have different bones, which implies that they all share a common ancestor.

• They all have similar bones, which implies that they all share a different ancestor.

• They all have similar bones, which implies that they all share a common ancestor.

The picture below shows parrots that existed in the past. Why are they all different colors?

• Different colors allow the parrots to fly at different levels so they can breed with other types of birds to become the same color.

• The parrots are different colors due to the color of the water they consume while eating various types of fruit in the environment.

• Changes in the environment have changed the available food sources, allowing the parrots with the best color to catch food easiest, survive, and reproduce better.

• Various explanations can explain why the parrots are different colors based on the amount of time the parrots sat in the sun.

Explain why the finches have different shaped beaks according to Charles Darwin.

• Environmental changes changed the type of available food, allowing finches with the best shaped beaks to survive and reproduce more.

• Environmental changes chemically altered the type of available food, allowing finches with the best shaped beaks to survive and reproduce more.

• Environmental changes changed the type of available food, killing finches with the best shaped beaks not allowing them to survive and reproduce more.

• Environmental changes changed the type of available water and space, allowing finches with the best shaped beaks to survive and reproduce more.

Why are adaptations important for an animals?

• They make life pass by more quickly for the animal.

• They help them survive in their environment.

• They complicate life for the surviving animal.

Charles Darwin wondered why the finches all had different shaped beaks. Which explains why?

• The finches all had the same beaks due to adaptations favorable for feeding on the types of food available and reproduction.

• The finches all had different beaks due to adaptations favorable for feeding on the types of food available and reproduction.

• The finches all had different beaks due to lack of vitamins favorable for feeding on the types of food available and reproduction.

• The finches all had different beaks due to adaptations favorable for feeding on the food that is no longer available in the area and reproduction.

• when scientists make observations about some aspect of the natural world when facts have been repeatedly confirmed through observations.
