Explanation:
Metabolism in eukaryotic cells depends on the endoplasmic reticulum because it transports materials between membrane-bounded organelles within the cell.
Sound production is also known as phonation, and involves the process of vibrations generated by a combination of respiration, the vocal organ and the vocal tract. The physical structures that birds use are highly similar to that of humans, and the sounds that is generated travels through respired air.
Polysaccharides are more difficult to digest then monosaccharides because they are much larger molecules.
A renewable resource is something that provides power but will never run out. Eventually natural gas and oil and coal will run out. Wind is renewable because it will never run out, unless the world ends, then it won't matter.
