They are composed of proteins. I cannot see the options but hopefully that answer is in one of them
I believe, for the artery, they have, an open, circular lumen an a thick media
Veins on the other hand, have somewhat collapsed lumen and a thinner media. Arteries are blood vessels that carry blood out of the heart to other parts of the body, all arteries carry oxygenated blood except the pulmonary artery which carries deoxygenated blood from the heart to the lungs. Veins carry blood from other body parts to the heart, all veins carry deoxygenated blood except the pulmonary vein which caries oxygenated blood from the lungs to the heart.
The correct answer is True.
I hope this helps you and have a great day!! :)
Reforestation is a biodiversity method that can increase the biodiversity by replanting with trees. Reforestation will help forest recuperate from logging, rest fires and human abuse. Replanting trees will increase the density and variety of the trees and by doing so, wildlife will also increase. Although reforestation is a common approach to relive forest, forest management is still needed to maintain the endemic or native species.
