#1. Which Of the following processes is not related to nutrition ?
The correct answer is D.Scouring.
Scouring is the process of cleaning raw wool, while the other options—ingestion, assimilation, and egestion—are all fundamental stages of nutrition in living organisms.
- The correct answer is B. Radiation.
Radiation is the transfer of heat through electromagnetic waves. The sun emits energy in the form of these waves, which travel through the vacuum of space and reach the Earth. Crucially, radiation doesn’t require a medium (like a solid, liquid, or gas) to transfer heat.
Other options:
- Convection: This involves the transfer of heat through the movement of fluids (liquids or gases). Warm air rises, cool air sinks – this is convection. While convection plays a role in distributing heat within the Earth’s atmosphere, it’s not how heat initially travels from the sun.
- Conduction: This is the transfer of heat through direct contact between substances. Think of a pan on a stove – the heat from the burner is conducted to the pan. Conduction requires a medium and is not how the sun’s heat reaches us.
Dispersion: This refers to the spreading out of something, like light separating into different colors through a prism. It’s not a method of heat transfer.
