The drawings below represent two human cell types: a neuron and a rod cell, which is found in the eye. A blue elongated structure labeled neuron branches out on both ends. On one end the branches extend from an area that contains a small circle with a tiny dot inside. Another structure is green and labeled rod cell. The top part is a cylinder shape with stacked discs inside. Attached to the bottom of this cylinder is an oval shape with a smaller oval inside. An elongated structure extends down from the oval and branches out. A blue elongated structure labeled neuron branches out on both ends.

Choose 1 answer: Choose 1 answer: (Choice A) Because the cells have undergone mitosis, the neuron and the rod cell contain different genes. A Because the cells have undergone mitosis, the neuron and the rod cell contain different genes. (Choice B) Because of differential gene expression, the neuron and the rod cell produce different proteins. B Because of differential gene expression, the neuron and the rod cell produce different proteins. (Choice C) Because the cells are the result of a fertilization event, the neuron and the rod cell contain different chromosomes. C Because the cells are the result of a fertilization event, the neuron and the rod cell contain different chromosomes
