Some students were discussing running the mile in PE. The students all agreed that the cardiovascular system was very important but they could not agree on what other system was important. Which of the following claims and reasoning would be MOST beneficial in their argument? (AKS 2b)

A.
Student 2 said the digestive system was also important because it breaks down waste produced by running, which the cardiovascular system transports to all the cells.

B.
Student 3 said the immune system was also important because it releases sweat from the body while running, which the cardiovascular system will transport away from all the cells.

C.
Student 1 said the respiratory system was also important because it brings oxygen into the body while running, which the cardiovascular system transports to all the cells.

D.
Student 4 said the muscular system was also important because it produces nutrients in the body while running, which the cardiovascular system will transport away from all the cells.

Bisphenol a (often called bpa) is a chemical found in products that people use every day, from water bottles to food containers to children's toys. unfortunately, bpa leaches out of its many products and makes its way into our bodies. what are the health effects of bpa exposure? ongoing research is finding that elevated exposure to bpa can affect a wide variety of developmental and physiological processes, but one of the first studies of bpa's health effects came about because of a simple mistake in the lab. at a laboratory at case western reserve university in 1998, geneticist patricia hunt was making a routine check of her female lab mice. as she extracted and examined developing eggs from the ovaries, she began to wonder what had gone wrong. she noticed that many of the eggs showed problems with their chromosomes, and some had irregular amounts of genetic material, which can lead to miscarriages and birth defects in mammals. she learned that a lab assistant had mistakenly washed the plastic mouse cages and water bottles with a harsh soap, releasing bpa from the plastic. knowing that bpa is an endocrine disruptor, a chemical that can enter organisms and mimic hormones, hunt set out to discover whether it had adversely affected her mice.
