Monosaccharide, disaccharides, and polysaccharides are the three major categories of molecules in Carbohydrates.
Monosaccharides, known as simple sugar, is the simplest form of carbohydrates. Its basic molecular formula is CH2O. Monosaccharides are glucose, fructose, and galactose. Its primary function is to be the source of energy of living organisms. It is also the primary requirement for the formation of disaccharides and polysaccharides.
Disaccharides are formed when two monosaccharides are bonded together through a covalent bond. Common Dissaccharides are sucrose (glucose+fructose) or table sugar, maltose (glucose+glucose), and lactose (glucose+galactose). Its primary function is to provide nutrition for monosaccharides. Sugar in food is mostly dissaccharides.
Polysaccharides are formed when another monosaccharides is bonded to the disaccharides. This bond is called glycosidic bond. Two major polysaccharides are starch and glycogen. Starch is made by plants while glycogen is made by animals. Polysaccharides' major function is to immediately release energy from its storage. When glucose is consumed, some of them are stored and will only be released when the body needs it to satisfy the body's immediate need of energy.
Final answer:
Glucose is a Monosaccharide, Starch is a Polysaccharide, and Sucrose is a Disaccharide. Monosaccharides are simple sugars, Disaccharides are two sugar molecules, and Polysaccharides are complex carbohydrates.
Explanation:
The carbohydrate molecules belong to the following classes:
- (I) Glucose belongs to the class of Monosaccharides.
- (II) Starch belongs to the class of Polysaccharides.
- (III) Sucrose belongs to the class of Disaccharides.
To explain, Monosaccharides are the simplest form of carbohydrates, such as glucose. Disaccharides are two monosaccharide molecules linked together, in this case, sucrose is composed of glucose and fructose. Polysaccharides are complex carbohydrates, made of many sugar units - starch is one such example.

A reproductive isolation mechanism in which females prefer to mate with males of their own species is a BEHAVIORAL mechanism.
- Reproductive isolation refers to the mechanisms that prevent a species from mating with others, which have fundamental importance from an evolutionary point of view.
These barriers to fertilization can be divided into:
- prezygotic isolation barriers, which prevent the fertilization of the egg
- postzygotic isolation barriers, which prevent the generation of fertile offspring.
- The most important prezygotic isolation barriers include, among others, habitat isolation, behavioral isolation, mechanical isolation, etc.
- Behavioral isolation mechanisms are characterized by mating rituals (for example, the songs of males in certain bird species), which are capable of generating reproductive barriers.
In conclusion, a reproductive isolation mechanism in which females prefer to mate with males of their own species is a BEHAVIORAL mechanism.

The isolating mechanism involved is the behavioral change (A).
Further Explanation:
Isolating mechanism are those characteristics of the species that prevents them to reproduce with other members of the species.
There are various types of isolating mechanism:
1. Behavioral- Reproductive isolation that arises due to the behavior of the individual during their mating period.
2. Temporal- The species breeds at different time or they may have different breeding season, therefore this can lead to reproductive isolation.
3. Geographical- The isolation of species because they occupies different habitats.
4. Anatomical- Isolation that arises due to different internal structure of the species.
Example of isolating mechanism - when two species of flies, Drosophila melanogaster and Drosophila simulans, can mate however they usually do not mate. But even though they are kept with each other in any lab, males court the females of both species but the females prefers to mate with males that belongs to the same species.This example shows the behavioral isolation.
