• Both are made up of cells.
The correct answer is (c) maintain homeostasis. Both blood cells and stomach cells play a role in maintaining the body's internal environment and ensuring that it stays balanced and stable. However, they achieve this through different mechanisms, with blood cells transporting oxygen and nutrients and stomach cells secreting enzymes for digestion. While blood cells do require iron for the production of hemoglobin, which is involved in oxygen transport, this is not a characteristic shared with stomach cells.
An eye doctor shines a bright light into a patient's eye. In one to two sentences, explain how the patient's brain perceives the bright light.
The bright light stimulates photoreceptor cells in the retina of the eye, which then send electrical signals through the optic nerve to the brain. The brain then processes these signals and translates them into the perception of a bright light.
