Question
Explain the ways by which solid waste can be disposed.
✓
Answer
Methods of Solid Waste Disposal:
- Open burning: Municipal waste is reduced by burning in open dumps but the unburnt waste serve as the breeding ground for rats and flies.
- Sanitary landfills: Wastes are dumped in a depression or trench after compaction and covered with dirt. But seepage of chemicals from these landfills can pollute underground water resources.
- Rag-pickers and kabadiwallahs: Wastes are collected and separated out into reusable or recyclable categories.
- Natural breakdown: The biodegradable materials are kept into deep pits in the ground for natural breakdown.
- Recycling: E-wastes can be recycled in specifically built factories or manually to recover important metals.
- Incineration: Majority of e-wastes generated in developed world is exported to developing world where they are incinerated.

Fitness is the end result of the ability to adapt and get selected by nature. Explain with suitable example.
Polymerase chain reaction (PCR) is a laboratory technique used to amplify DNA sequences. The method involves using short DNA sequences called primers to select the portion of the genome to be amplified. The temperature of the sample is repeatedly raised and lowered to help a DNA replication enzyme copy the target DNA sequence. The technique can produce a billion copies of the target sequence in just a few hours.
