The Himalayan rabbit’s habitat has cold, snowy winters and mild summers. The body is typically covered in white fur except for the nose, feet, tail, and ears, which are covered in black fur. A scientist shaved an area of white fur on the back of a Himalayan rabbit and placed an ice pack over the shaved area. The shaved area grew black fur. Which of these best explains why the hair that grew back where the ice pack was placed was black and not white?

• The genes for black hair were activated by specific temperatures.

• The white hair mutated to black hair as the rabbit’s body temperature decreased.

• The coat color changed from white to black with the age of the rabbit.

• White hair only grows during certain times of the year.

6(G)In the early 1900s, Thomas Hunt Morgan was among the first scientists to contribute to the chromosome theory of heredity. Morgan’s investigations into heredity in fruit flies led him to propose that the event represented in the diagram sometimes occurs. Which statement about the event represented in the diagram is valid?

• The event represents RNA translation in the smooth endoplasmic reticulum.

• The event takes place in bacterial cells.

• The event produces genetically identical daughter cells.

• The event provides genetic diversity in eukaryotic cells.

• The number of carbons in the DNA molecule.

• The sequence of nucleotide bases in the DNA molecule.

• The sequences of phosphates along each DNA strand

Scientists use zebra fish to study human genetic diseases because zebra fish and humans share many of the same genetic diseases. Which statement describes why zebra fish experience similar genetic diseases as humans?

• Zebra fish have nucleotide sequences similar to those of humans.

• Zebra fish go through embryonic stages similar to those of humans.

• Zebra fish produce gametes through a process that is similar to that of humans.
