Mutation is the process by which there is a permanent alteration in the DNA sequence of an organism's genome. These changes can occur due to various factors such as exposure to radiation, chemicals, or errors during DNA replication. Mutations can happen in somatic cells, which affect only the individual, or in germ cells (egg or sperm cells), which can be passed on to offspring.

Paternity testing, also known as DNA testing for paternity, is a reliable and accurate method used to determine the biological father of a child. It is based on the analysis of DNA (deoxyribonucleic acid), which is the genetic material found in cells. Every individual inherits their DNA from their biological parents, half from the mother and half from the father.

Heterotrophic nutrition is a type of nutrition in which an organism obtains its food by consuming organic matter from other organisms. In the case of pitcher plants, they capture and digest insects as a source of nutrients to supplement their diet, especially in nutrient-poor environments. This carnivorous adaptation is a specialized form of heterotrophic nutrition, as the pitcher plant relies on consuming other living organisms (insects) to meet its nutritional needs. The pitcher plant is a carnivorous plant that has modified leaves forming pitcher-like structures.

Pollination is not an activity associated with termites. Pollination is primarily carried out by various animals, such as bees, butterflies, birds, and bats, which transfer pollen from one flower to another, leading to fertilization and seed production. While some insects, like bees, are important pollinators, termites are not known for their role in pollination.
