14. Two sharks have different parents. The two sharks have different proteins in their cells for the dark color on the tip of their fins. What can you say about the color on the tip of the two sharks' fins?

• The fins will be the same color since all sharks have the same fin color.

• The fins will be the same color because even with different proteins for fin color, the proteins can connect in the same way.

• The fins will be different colors since offspring from different parents will have different colored fins.

• The fins will be a different color since their proteins for fin color are different so the proteins will connect in different ways.

9. Hannah is trying to figure out how tooth size is determined in two different wolves. In wolf 1, the copies of the gene are different from each other. In wolf 2, the copies of the gene are the same as each other. How does this affect how many types of proteins there are in each tooth cell?

• Wolf 1 has one type of protein for the tooth size feature. Wolf 2 has one type of protein for the tooth size feature.

• Wolf 1 has two types of protein for the tooth size feature. Wolf 2 has one type of protein for the tooth size feature

• Wolf 1 has two types of protein for the tooth size feature. Wolf 2 has two types of protein for the tooth size feature

• It is impossible to say anything about proteins from the given information.

10. There are two bears that both have the same proteins for ear shape in their cells. The bears have different parents. What can you say about the bears' ear shape?

• They will have the same ear shape since their proteins for ear shape are the same so the proteins will connect in the same way.

• They will have the same ear shape since all bears have the same ear shape.

• They will have different ear shapes because even with the same proteins for ear shape, the proteins can connect in different ways.

• They will have different ear shapes since only offspring from the same parents have the same ear shape.

8. The body cells of scorpions have proteins that connect together. In one scorpion, the structure of the proteins in the body cells "changed," but the amount of that type of protein in the cell stayed the same. What happened to the function of that type of protein?

• The changed protein connects differently, so we will see what happens.

• The changed protein connects differently, so its function changes

• The changed protein connects in the same way, but the functions likes to party.

• The amount of that type of protein stayed the same, so its function doesn’t change.

6. Two rabbits have different parents. One rabbit has ears that flop over, and the other rabbit has ears that stand straight up. Why do the rabbits have ears with different shapes?

• The rabbits have different versions of the gene for ear shape. The genes are only standing straight up in the cells of one rabbit’s ears.

• The rabbits have different versions of the gene for ear shape, which instruct for different proteins that connect in different ways to make different ear shapes.

• Each rabbit has a different ear shape because offspring from different parents will have different ear shapes.

• Each rabbit has a different ear shape because they have different versions of the gene for ear shape that connect together to make different ear shapes.
