Brian, age 28, began an aerobic exercise program 2 years ago. brian now competes in long-distance cycling events and considers himself to be an endurance athlete who is in the "best shape of his life." an echocardiogram reveals a slightly enlarged left ventricle. make the connection. drag and drop the proper term for the cellular change or injury that is best exemplified by the case scenario. apoptosis, atrophy, benign neoplasia, dysplasia gangrene, hyperplasia, intracellular accumulation, malignant neoplasia, metaplasia, necros, pathological hypertrophy, physiological hypertrophy, pathologic calcification

The correct answer is: physiological hypertrophy.

Explanation:

Brian is a young and very healthy young man; as an athlete, the amount of physical effort he engages in is much greater than the amount on non-athletes. For this particular reason, his heart (specifically, his left ventricle, which pumps blood to the aorta for it to reach the his whole body) has begun to enlarge in size, for it to be able to respond accordingly to the highly active lifestyle that he has. This is known as physiological hypertrophy: physiological refers to the normal function of the human body, while hypertrophy means enlargement of one's organs, tissues or cells.

the correct answer is "pioneers carried all of their possessions on long and dangerous trails".

the first wave of pioneers travelled in 1842. they were merely 100 people. the next year that sum climbed to 1000 men, women, and children. these people travelled around 2,000 miles to oregon in the hopes of a better life. although the first part of the trip didn't present many obstacles, as time and miles went by they learnt that threat came from simple things, like becoming ill due to unclean water or bad food.

the weather didn't much, as wagons couldn't protect them from storms. as they travelled through the desert, the intense heat caused wood to shrink. their own lips abscessed and split because of the dry air. the only cure for this was to rub axle grease on their lips.

even crossing rivers was dangerous. sometimes wheels were damaged by unseen rocks on shallow water. mud didn't much either. pioneers were afraid of indian attacks, but there aren't many records of fights between pioneers and native americans. accidents happened because of negligence, exhaustion, guns, and bad weather.

history says that 1 of 10 pioneers who travelled to oregon didn't survive the journey. diseases spread fastly because they didn't have doctors and medical care was ofently improvised. one of the most deadly diseases they came upon was cholera, which became a worldwide pandemia.
