Answer the following question given this paragraph: Which of the following statements about the human eye is false? a. Rods detect color, while cones detect only shades of gray. When light enters the retina, it passes the ganglion cells and bipolar cells before reaching photoreceptors at the rear of the eye. The iris adjusts the amount of light coming into the eye. The cornea is a protective layer on the front of the eye. The main function of the lens is to focus light on the retina and fovea centralis. The lens is dynamic, focusing and refocusing light as the eye rests on near and far objects in the visual field. The lens is operated by muscles that stretch it flat or allow it to thicken, changing the focal length of light coming through it to focus it sharply on the retina. With age comes the loss of the flexibility of the lens, and a form of farsightedness called presbyopia results. Presbyopia occurs because the image focuses behind the retina. Presbyopia is a deficit similar to a different type of farsightedness called hyperopia caused by an eyeball that is too short. For both defects, images in the distance are clear but images nearby are blurry. Myopia (nearsightedness) occurs when an eyeball is elongated and the image focus falls in front of the retina. In this case, images in the distance are blurry but images nearby are clear. There are two types of photoreceptors in the retina: rods and cones, named for their general appearance as illustrated in Figure 36.18. Rods are strongly photosensitive and are located in the outer edges of the retina. They detect dim light and are used primarily for peripheral and nighttime vision. Cones are weakly photosensitive and are located near the center of the retina. They respond to bright light, and their primary role is in daytime, color vision. Q: What are the two types of photoreceptors in the retina? Choices: - holes and cones - circles and cones - images and cones - rods and cones A:
rods and cones

Q: Answer the following question given this paragraph: Plants don't have an immune system, but they do respond to disease. Typically, their first line of defense is the death of cells surrounding infected tissue. This prevents the infection from spreading. Q: Because plants lack what kind of system, their first line of defense is usually the death of cells surrounding infected tissue to prevent spread of infection? Choices: - nervous system - digestion system - hormones system - immune system A:
A: immune system
