Limit of BOD prescribed by Central Pollution Control Board for the discharge of industrial and municipal waste water into natural surface water, is:
- < 3.0 ppm
- < 10 ppm
- < 100 ppm
- < 30 ppm
The Correct Option is B
Solution and Explanation
The limit of BOD (Biochemical Oxygen Demand) prescribed by the Central Pollution Control Board (CPCB) for the discharge of industrial and municipal wastewater into natural surface water typically falls within the range of < 10 ppm. This limit can vary depending on the specific regulations and water quality standards in a given region, but it is common for such discharges to have a BOD level of less than 10 parts per million (ppm) to protect the water quality and aquatic ecosystems.
So, the correct option is (B): < 10 ppm

- The plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant \(K_1\) and \(K_2\) with thickness \(d/2\) and \(d/2\) respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If \(K_1 = 1.25 K_2\), the value of \(K_2\) is :

DNA Replication
The process by which the genome’s DNA is copied in cells is called DNA Replication. It must first copy (or replicate) its entire genome before cell division so that each resulting daughter cell ends up with its own complete genome.
It is the natural cycle of creating two indistinguishable imitations of DNA from one unique DNA molecule. DNA replication happens to take all things together living creatures going about as the most core part for organic legacy. This is important for cell division during the development and fixation of harmed tissues, while it likewise guarantees that every one of the new cells gets its duplicate of the DNA. The phone has the unmistakable property of division, which makes replication of DNA fundamental.
The parental DNA stays together, and the recently shaped daughter strands are together in conservative replication. The semi-conservative strategy recommends that every one of the two parental DNA strands goes about as a format for new DNA to be integrated; after that each two-fold abandoned DNA incorporates one "old" strand (parental) and one "new" strand.
