Sh’qira reads an article about a family of wildcats. One of them had a mutation for tooth sharpness. Which of these statements about the wildcat with the mutation is true?

• There must have been a change in the wildcat’s genes.

• The wildcat must have sharper teeth.

• There will be no change to the wildcat’s teeth.

• The wildcat must have less sharp teeth.

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.

The wing cells of dragonflies have proteins that connect together. In one dragonfly, the structure of the proteins in the wing 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 amount of that type of protein stayed the same, so its function doesn’t change.

• The changed protein connects differently, but its function doesn’t change.

• The changed protein connects differently, so its function changes.

• The changed protein connects the same, but its function changes.

______ are instructions for proteins.

• Nucleus

• Ribosomes

• Chromosomes

• Genes
