Hair Coloring Experiment We test a new brand of red hair coloring (Red Hair Paint) on 6th grade students at Beville Middle School to see how well the coloring “takes” and lasts on different colors of hair. We compare “Red Hair Paint” to a popular brand already being used, L’Oreal. We test both brands of coloring on 40 students (10 blonds, 10 brunettes, 10 with black hair and 10 with red hair)…some with straight hair and some with curls. The students use the coloring for two months, under identical washing and combing conditions and in the same kinds of environments (temperature, humidity, etc). Identify the following:

(what we are testing it on)

coal is not sustainable because it will one day run out.

thats not a question

you know that this symptom is misleading and quite often is related to: heart attack

a heart attack is a condition that occurs when the blood flow that transports oxygen to the heart muscle is damaged or cut off completely. the coronary arteries that supply the heart muscle with blood flow can be blocked by the accumulation of plaque. also, when the plaque within the heart artery breaks, it creates blood clot that can also hinder the blood flow. men that are over 45years of age and women that are over 55years of age are at risk of having a heart attack. the symptoms of a heart attack include chest discomfort, chest pain, coughing, and shortness of breath.
