Adisaccharide is formed by the chemical bonding of a) two monosaccharides b) two polysaccharides c) one monosaccharide and one polysaccharide d) all the above

The correct option is A.

Explanation:

A disaccharide refers to a sugar that is formed by the chemical bonding of two monosaccharides which are joined together via glycosidic bond.

A monosaccharide refers to any sugar that can not be reduced further to give a simpler sugar. When two monosaccharides residue come together they form a disaccharide ('Di' means two).

One good example of monosaccharide is glucose. When two glucose molecules or glucose and another monosaccharide join together they give rise to disaccharide such as surcose, lactose and maltose. The components of these disaccharides are given below:

1. Sucrose (Table sugar): Glucose + fructose.

2. Lactose (Milk sugar): Glucose + galactose.

3. Maltose: Glucose + glucose.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
