Answer: relationships between two continuous variables.
◍ What do the control and experimental groups differ by?.
Answer: one variable
◍ What is the dependent variable.
Answer: how much will it grow - What I am measuring
◍ Reasons for Heart attacks.
Answer: 1) plaque builds up in the coronary arteries2) a piece of plaque
breas, causing a clot to form3) clot blocks blood flow through a coronary
artery4) myocardium in that area dies off because of lack of oxygen
