Atherosclerosis
Explanation:
Correct order of the sequence of events that leads to atherosclerosis is:
c, d, b, a
Development of atherosclerosis is caused by a high concentration of LDL‐cholesterol in the blood, and lowering the level of LDL‐cholesterol reverses atherosclerosis thus preventing cardiovascular disease
Cholesterol is the key component of arterial plaques which gave rise to the cholesterol hypothesis for the pathogenesis of atherosclerosis
Population studies have shown that elevated levels of both LDL cholesterol and apolipoprotein B (apoB) 100, which is the main structural protein of LDL, are directly associated with risk for atherosclerotic cardiovascular events

In biology, histones are highly alkaline proteins found in eukaryotic cell nuclei that package and order the DNA into structural units called nucleosomes. They are the chief protein components<span> of </span>chromatin<span>, acting as spools around which DNA winds, and playing a role in </span>gene regulation<span>.</span>
        
             
        
        
        
We sprinkle powder on carrom board to make the surface of the board smooth. This reduces the friction between the surface of the carrom board, the striker and the coins. As a result, the coins and the striker can move easily on the carrom board.
