If a flood occurs in the natural rubber environment, it will ruin the rubber production process. The flood would damage a huge percentage of rubber trees if there was a large quantity of restriction. This natural rubber is required for the production of synthetic polymers. Without the rubber, there would be a restricted supply and a significant decline in synthetic polymers due to ecological damage caused by the flood.
The best answer is B (semi permeable)
The cell membrane of a red blood cell is semi permeable membrane. This is a type of biological membrane that will allow certain molecules or ions to pass through while barring others.
Red blood cells have very thin membranes that allow oxygen diffuse through quickly. They are also permeable to water and osmosis across the membrane occurs very rapidly. In the body, they are bathed in isotonic plasma in which case water movement into the cell is equal to water movement out of the cell and so the cells remain intact.
Plants release water into the atmosphere through a process called Transpiration...
Asexual organisms produce clones of themselves. That leaves the organism prone to being wiped out in its entirety, because every individual is equally in trouble when danger strikes. A virus or predator that affects one affects them all. It has no possibility of exploring new places, new foods, new methods of escape.
