A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance.
A gene is spliced by assembling different gene segments and DNA sequences into a product called a chimera. Scientists join these snippets in a circular piece of DNA called a plasmid. Scientists use a complex process to clone genes from an organism's DNA.

The correct answer is explained below:
Explanation:
- Flooding and intrusion of salt water in the low lying areas can adversely affect human life. This can happen in the following ways:
- Flooding can cause many people to die due to drowning in the flood water.

- The saline water percolates through the ground and mixes with the fresh water present in the water table, thereby making them saline and non-consumable.
