I believe it is natural selection. Natural selection is when over a period of time, traits that are formed to help the organism survive, are passed to the next generation. For example, if there were two types of rabbits. One had black fur and the other was white. They both lived in the artic. The black furred rabbits are mostly eaten by predators because their black fur is easily seen against the ice and snow. Over a period of time, the black furred rabbit would die out. The next generation would mostly have white fur to help them survive.

Without the rough er cells would ?
Degger [83]
There are two basic types of ER. Both rough ER and smooth ER have the same types of membranes but they have different shapes. Rough ER looks like sheets or disks of bumpy membranes while smooth ER looks more like tubes. Rough ER is called rough because it has ribosomes attached to its surface. 

<span>The double membranes of smooth and rough ER form sacs called </span>cisternae. Protein molecules are synthesized and collected in the cisternal space/lumen<span>. When enough proteins have been synthesized, they collect and are pinched off in </span>vesicles<span>. The vesicles often move to the Golgi apparatus for additional protein packaging and distribution. </span>

Smooth ER (SER)<span> acts as a storage organelle. It is important in the creation and storage of lipids and </span>steroids<span>. Steroids are a type of ringed organic molecule used for many purposes in an organism. They are not always about building the muscle mass of a weight lifter. Cells in your body that release oils also have more SER than most cells. </span><span>
