Trivia: What waxy substance in the blood can cause health problems when in excess?
Alveolus
Niacin
Cholesterol
Biotin
The correct answer is Cholesterol
So why is this answer correct? : Despite its reputation, cholesterol isn’t always bad. It is a natural component of the blood that is needed to build cells and make vitamins and hormones. There are two types of cholesterol: LDL cholesterol (the “bad” kind) and HDL cholesterol (the “good” kind). Too much of the bad kind or not enough of the good kind can cause heart problems.
