Homeostasis refers to the maintenance of a constant internal environment. This includes things like blood glucose, internal pH, blood volume, etc.  Question 25 7 / 8 pts Your Answer: Nice job. I think for your second sentence you meant, they have electrons missing in their outer shell. Free radicals easily attract electrons from a stable molecules (oxidation), possibly disrupting its function. Antioxidants (found in the foods you listed), stabilize free radicals by donating electrons to them. Quiz Score: 79 out of 85 Homeostasis, as deXned in Chapter 1, is the unique ability of living things to maintain an internal temperature. The human body strives to maintain an internal temperature of 98.6 degrees Fahrenheit. Our bodies strive to keep this internal body temperature by sweating in hot weather and shivering in colder weather. What is a free radical? According to our text, what type of nutrient helps to destroy them? Free radicals are unstable molecules that are released into our cells. They are electrons missing an outer shell. According to our textbook, eating certain fruits and vegetables with certain phytochemicals can help counter the production of these free radicals and destroy them. Examples given are Vitamin C, strawberries, cantaloupes, and tomatoes.
