RER appears rough because of presence of ribosomes over them.
Viruses are not supposed living because they dont have any cellular structure and dont perform metabolic activities.
The fluid substance which is present in centre of prokaryotic cell which contains its DNA is called nucleoid. It doesnt have a nucleqr membrane.
When dry rainsins are kept in water for some time, they swell up because the water molecule concentration inside raisin is less than outside it, the process of endosmosis takes place.
The movement of water moleciles from higher concentration to lowwr concentration is called osmosis.
