The Verhulst-Pearl Logistic Growth equation describes the growth of a population in a limited environment. It accounts for the carrying capacity (K), which is the maximum population size that the environment can support. The equation is given as:
\(\frac{dN}{dt} =rN (\frac{K - N}{K})\)
Where:
\(\frac{dN}{dt}\) is the rate of change of the population size,
\(N\) is the current population size,
\(K\) is the carrying capacity (maximum population size the environment can support),
\(r\) is the intrinsic growth rate (rate of reproduction).
This equation shows that as the population NNN approaches the carrying capacity KKK, the growth rate slows down, reflecting the limitations of resources.
The Verhulst-Pearl Logistic Growth model is represented by the equation:
\( \frac{dN}{dt} = rN \frac{K - N}{K} \)
Where:
This equation describes how the growth rate is proportional to both the size of the population and the available resources, considering the environmental limitations (carrying capacity). As the population size \( N \) approaches the carrying capacity \( K \), the growth rate slows down, leading to a sigmoid or S-shaped curve.
Therefore, the correct equation from the given options for Verhulst-Pearl Logistic Growth is: \( \frac{dN}{dt} = rN \frac{K - N}{K} \)

The Right to Information Act 2005 (Act No. 22/2005) is a law enacted by the Parliament of India giving Indians access to government records. Under the terms of the Act, any person may request information from a ”public authority” (a body of Government or instrumentality of State) which is expected to reply expeditiously or within thirty days. The Act also requires every public authority to computerize their records for wide dissemination and to proactively publish certain categories of information so that the citizens need minimum recourse to request for information formally. This law was passed by Parliament on 15 June 2005 and came into force on 13 October 2005. Information disclosure in India was hitherto restricted by the Official Secrets Act 1923 and various other special laws, which the new RTI Act now overrides. The Act specifies that citizens have a right to:
• Request any information (as defined)
• Take copies of documents
• Inspect documents, works and records
• Take certified samples of materials of work.
• Obtain information in the form of printouts, diskettes, floppies, tapes, video cassettes or in any other electronic mode.

There has been greater recognition that both men and women are constrained by dominant gen der identities. For instance, men in patriarchal societies feel they must be strong and successful. It is not manly, to express oneself emotionally. A gender-just society would allow both men and women to be free. This, of course, rests on the idea that for true freedom to grow and develop, injustices of all kinds have to end. The idea of a gender-just society is based upon two important factors- educated women with multiple roles and improved sex ratio. The programme of the Government of India, Beti Bachao, Beti Padhao Yojana is an important effort in the actualization of a gender-just society.
