Nutrients are delivered and waste products are carried away from the cells of the posterior segment of the eye by blood vessels. However, the cells in the cornea and lens (in the anterior segment) are avascular. Which is the best explanation for how these cells are maintained?
◦ The aqueous humor is continuously replenished and flows from the ciliary process to drain in the scleral venous sinus.
◦ The metabolic activity of these cells is very low. They produce little waste and need few nutrients.
◦ These cells, like the cells of the corneal layer of the integument are not living cells.
◦ The nutrients and waste products of the anterior segment diffuse into and through the vitreous humor of the posterior segment.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
