Why are some of us more prone than others to coronary heart disease?
cricket20 [7]
"Coronary heart disease, North America’s number one cause of death, has been linked with the competitive, hard-driving, impatient, and (especially) anger-prone Type A personality. Under stress, the body of a reactive, hostile person secretes more of the hormones that accelerate the buildup of plaque on the heart’s artery walls. Type B personalities are more relaxed and easygoing. Chronic stress also contributes to persistent inflammation, which heightens the risk of clogged arteries and depression."

OR

Coronary heart disease (CHD) could be the thinning or impediment in the coronary thrombosis veins, normally brought on by coronary artery disease. Coronary artery disease (at times termed “stiffing” or maybe “blocking” in the arterial blood vessels) may be the build-up associated with trans fat and fatty deposits (named plaques) around the intrinsic artery walls.

Explanation:

Based on the data that was derived from the study we can conclude that Genes and the environment affect antipredator behavior. This is because regardless of the difference in the environment they were reared in both groups fled from the predator which is a genetic trait that has been passed down from generation. Yet, the group reared in low-temperature conditions fled sooner than those reared in high-temperature conditions meaning that the environment has affected the survival and antipredator behavior of the spiders.
