Glassy igneous rocks (i.e. obsidian) are cooled very rapidly.
An object that absorbs light would be much hotter upon touch. It might also expand by a few milimeters depending on what material it's made of.
<h3>Lipoproteins</h3>
Explanation:
Lipoproteins are aggregate molecules of lipids and proteins which carry cholesterol in the blood. Cholesterol binds with water-soluble carrier molecules of the lipoproteins.
Based on their density, lipoproteins are classified as very low density lipoproteins (VLDL), low density lipoprotein (LDL), high density lipoprotein (HDL)
The serum lipoprotein levels are diagnostic markers to detect blood fat levels and are checked in the blood lipid profile tests.
If LDL levels are increased it indicates higher risk for heart diseases like atherosclerosis
If HDL is increased, it reflects a healthy heart and reduces the risk for heart diseases or failure
