Answer:
Dissimilar organisms might have evolved from a distant, common ancestor.
Explanation:
First of all we should know species. Species is considered as a basic unit of taxonomic classification of an organism.
Initially, the scientists are agreed on this phenomenon that all distinct species are evolved gradually from common ancestor. Today, the species which are different from each other just like hummingbirds, humans and whales are from the same ancestor but with the time passage genetic mutation occurs and at the end dissimilar organisms we can see in our environment/surroundings.

Answer:
B. Polysaccharide
Explanation:
A polysaccharide is a carbohydrate molecule made up of several units of monomers called monosaccharides linked together by glycosidic bonds. The monosaccharide is the simplest unit of a carbohydrate with the general formula, (CH2O)n.
However, the monosaccharides, which include glucose, fructose, galactose etc can link up by a bond to form a much larger carbohydrate molecule called POLYSACCHARIDE. As depicted in the image attached to this question, each ring is a monosaccharide, which becomes linked to one another to form a polymer called polysaccharide. Examples of polysaccharides are starch, glycogen, cellulose
