A medical researcher measured the diastolic wall thicknesses of the arteries in a young, healthy test subject. The test subject
came back 20 years later to have the measurements repeated. The measurements revealed that the subject's artery walls were half as thick as they were originally. Which of the following is the most likely long-term effect if the measured trend continues? a) Arteries and veins will fuse, causing oxygenated and deoxygenated blood to mix.
b) Arteries will be unable to withstand the pressure exerted by the heart, causing an aneurysm.
c) Blood volume will increase, causing the kidneys to work harder to maintain blood pressure.
d) Blood pressure will decrease, causing nausea, dizziness, loss of consciousness, and potential death.
<span>If the measurements of diastolic wall thickness decreased by half after 20 years and if the decrease will continue, it may result to:</span>
b) Arteries will be unable to withstand the pressure exerted by the heart, causing an aneurysm.
<span>An aneurysm<span> refers to a weakening of an artery wall that creates a bulge or a balloon of the artery that may rupture leading to death. Most of it </span>develops<span> after age 40 years old. </span></span>
Myrmecophytes, otherwise known as ant-plants, share a mutualistic relationship with a colony of ants. This is when two organisms of different species each benefit from the activity of the other. There are over 100 different genera of myrmecophytes that can be found across the world's tropical regions
Earth and its atmosphere are continuously altered. Plate tectonics shift the continents, raise mountains and move the ocean floor while processes not fully understood alter the climate. Such constant change has characterized Earth since its beginning some 4 billion years ago.
