Help plz A number of studies are carried out in order to verify if there is a relation between the death rate by cardiac diseases ánd the cholesterol level in the blood. The results are shoen in the adjacent graph..

1) explain the relation between the level of blood cholesterol and the risk of cardiac accident
2) firmulate the hypothesis tested in this study
3) what do you conclude concerning the formulated hypothesis?
​

The correct answer is :

1. increase in cholesterol level leads to more death due to cardiac disease.

2. Hypothesis: "if the cholesterol level is high in an individual, then the risk of death due to cardiac disease is high"

3. Everyone should limit or control their cholesterol level to avoid cardiac disease or it might be lethal.

Explanation:

In this graph, it is represented that there is an increase in the deaths due to cardiac disease with the increase in the cholesterol in the body. The death increase slowly up to 2.5 gL and after that, there is a huge spike in death, which explains that the higher the cholesterol level higher the chances or risk of death due to cardiac disease.

Hypothesis: "if the cholesterol level is high in an individual, then the risk of death due to cardiac disease is high"

On the basis of this one should control its body cholesterol to avoid the chances of cardiac disease as it may lead to death.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
