The muscles won’t contract. B. The muscle tissues will have to work much harder, and the individual muscles will tire more quickly. C. The muscle cells will start to twitch, which will cause the individual muscles to become weaker. D. The individual cells will lose their ability to coordinate their movements. How do muscle cells form different types of tissues? A. Information in the DNA of the nucleus can tell muscle cells how to develop and perform special functions. A group of these cells that perform similar functions become muscle tissue. B. Information in the RNA of the nucleus can tell muscle tissues how to develop and perform special functions. A group of these cells that perform similar functions become muscle systems. C. Messages from the brain can tell muscle cells how to develop and perform special functions. A group of these cells that perform similar functions become muscle tissue. D. Messages from the heart can tell muscle cells how to develop and perform special functions. A group of these tissues that perform similar functions become muscle organs.

How does the immune system work together with the circulatory system to function properly? A. Red blood cells move through the body (to parts where they are needed) in the blood vessels of the circulatory system to fight infection. B. The white blood cells of the immune system fight and destroy pathogens. C. Pathogens released by immune cells cause increased blood flow to the infection site, which brings other pathogens to the area more quickly. D. The infection site receives oxygen-depleted blood from the circulatory system’s arteries, so the immune system works harder.

A medical researcher measured the diastolic wall thicknesses of the arteries in a young, healthy test subject. The test subject came back 20 years later to have the measurements repeated. The measurements revealed that the subject’s artery walls were half as thick as they were originally. Which of the following is the most likely long-term effect if the measured trend continues? .Arteries and veins will fuse, causing oxygenated and deoxygenated blood to mix. Arteries will be unable to withstand the pressure exerted by the heart, causing an aneurysm. Blood pressure will decrease, causing nausea, dizziness, loss of consciousness, and potential death. Blood volume will increase, causing the kidneys to work harder to maintain blood pressure.
