Circuit training is a very popular and effective variation for the improvement of physical fitness components. In circuit training several exercises are done one after the another. Compeletion of one set of each exercise in rotation is called one round. There are normally three or more rounds in a circuit training which consists of 7-12 exercises generally.

The exercises in a circuit are arranged in such a manner that different muscle groups are exercised in rotation. A specific circuit, however, can consist of several exercises involving the same muscle groups.

The bicameral legislature is one where the legislature consists of two houses, Chambers, factions for representation. E.g., the Congress of the United States which consists of a House of Representatives, and a  Senate and Indian Parliament which consists of the House of People and Council of States. 
Bihar, Karnataka, Maharashtra, Telangana and Uttar Pradesh  are bicameral legislature state in India. 

The anti-defection law was passed by parliament in 1985 by 52nd Amendment to the Constitution. It added the Tenth Schedule which laid down the process by which legislators may be disqualified on grounds of defection from one political party to another.

A pair of sets which does not have any common element are called disjoint sets. For example, set A={2,3} and set B={4,5} are disjoint sets. But set C={3,4,5} and {3,6,7} are not disjoint as both the sets C and D are having 3 as a common element.

The basic role of accounting is to provide relevant financial information to the businessmen and the stakeholders. Furthermore, facilitating the decision making processes and keeping them updated. There are two types of functions of accounting, first, historical functioning and second, managerial functionals. The main functions of accounting are to keep an accurate record of financial transactions, to create a journal of expenditure, and to prepare this information for statements that are often required by law. The most basic function is to record the data.

The complement of the union of two sets is equal to the intersection of their complements and the complement of the intersection of two sets is equal to the union of their complements. These are called De Morgan’s laws.

For any two finite sets A and B;

(i) (A U B)' = A' ∩ B' (which is a De Morgan's law of union).

(ii) (A ∩ B)' = A' U B' (which is a De Morgan's law of intersection).

Proof of De Morgan’s law: (A U B)' = A' ∩ B'

Let P = (A U B)' and Q = A' ∩ B'

Let x be an arbitrary element of P then x ∈ P ⇒ x ∈ (A U B)'

⇒ x ∉ (A U B)

⇒ x ∉ A and x ∉ B

⇒ x ∈ A' and x ∈ B'

⇒ x ∈ A' ∩ B'

⇒ x ∈ Q

Therefore, P ⊂ Q …………….. (i)

Again, let y be an arbitrary element of Q then y ∈ Q ⇒ y ∈ A' ∩ B'

⇒ y ∈ A' and y ∈ B'

⇒ y ∉ A and y ∉ B

⇒ y ∉ (A U B)

⇒ y ∈ (A U B)'

⇒ y ∈ P

Therefore, Q ⊂ P …………….. (ii)

Now combine (i) and (ii) we get; P = Q i.e. (A U B)' = A' ∩ B'

Proof of De Morgan’s law: (A ∩ B)' = A' U B'

Let M = (A ∩ B)' and N = A' U B'

Let x be an arbitrary element of M then x ∈ M ⇒ x ∈ (A ∩ B)'

⇒ x ∉ (A ∩ B)

⇒ x ∉ A or x ∉ B

⇒ x ∈ A' or x ∈ B'

⇒ x ∈ A' U B'

⇒ x ∈ N

Therefore, M ⊂ N …………….. (i)

Again, let y be an arbitrary element of N then y ∈ N ⇒ y ∈ A' U B'

⇒ y ∈ A' or y ∈ B'

⇒ y ∉ A or y ∉ B

⇒ y ∉ (A ∩ B)

⇒ y ∈ (A ∩ B)'

⇒ y ∈ M

Therefore, N ⊂ M …………….. (ii)

Now combine (i) and (ii) we get; M = N i.e. (A ∩ B)' = A' U B'

Since A is subset of B - Each element of the set A is in the set B

So therefore A union B = B

False fruit is a fruit formed from other parts of the plant as well as the ovary, especially the receptacle, such as the strawberry or fig. Mango develops from a ripened ovary and thus is called a true fruit. It is a kind of drupe. Apple develops from a ripened thalamus and is a false fruit. An accessory fruit (sometimes called false fruit, spurious fruit, pseudofruit, or pseudocarp) is a fruit in which some of the flesh is derived not from the ovary but from some adjacent tissue exterior to the carpel. Fruits derived from the ovary and other accessory floral parts are called false fruits.

Accounting is the process of systematically recording, measuring and communicating information about financial transactions. The three major financial statements produced by accounting are the profit and loss statement, the balance sheet and the cash flow statement. It is a systematic process of identifying, recording, measuring, classifying, verifying, summarizing, interpreting and communicating financial information. It reveals profit or loss for a given period, and the value and nature of a firm's assets, liabilities and owners' equity. Accounting provides information on the.

Stoichiometry as the calculation of products and reactants in a chemical reaction. It is basically concerned with numbers.
Stoichiometry helps us determine how much substance is needed or is present. Things that can be measured are;

1. Reactants’ and Products mass
2. Molecular weight
3. Chemical equations
4. Formulas

VSEPR notation gives a general formula for classifying chemical species based on the number of electron pairs around a central atom. Note, however, that not all species have the same molecular geometry. For example, carbon dioxide and sulfur dioxide are both species, but one is linear and the other is bent. It is the relative arrangement of bonded atoms in a molecule. The way in which the bonded atoms direct themselves around the central atom is explained on the basis of this theory.

Sociology is the study of societies and how humans act in groups. Sociology is a social science. People who study sociology are called sociologists. A society is the community of people living in a particular country or region and having shared customs, laws, and organizations. The two major types of sociology that emerged were qualitative sociology and quantitative sociology. Today, most universities use both qualitative and quantitative methods of inquiry, and one method is not necessarily better than the other. Sociologists today employ three primary theoretical perspectives: the symbolic interactionist perspective, the functionalist perspective, and the conflict perspective. These perspectives offer sociologists theoretical paradigms for explaining how society influences people, and vice versa.
