What are the characteristics of living things?The characteristics of living things are as follows:
They have a tendency to construct a balance from the surrounding atmosphere through the process of homeostasis. They have the capability to grow, reproduce, and adapt to the surrounding environment. They perform an act of breathing and move from one place to another. They require food in order to derive energy.A Microscope is a laboratory instrument that is remarkably utilized in order to visualize small objects or cell samples that are too small to examine with unaided eyes. So, any living organism is definitely made of cells that are easily distinguished with the help of a microscope.
Therefore, taking a small sample to see if it is made of cells using a microscope signifies an experiment that can determine if an object is a living thing. Thus, the correct option for this question is A.

What is Food?Food is a substance consisting essentially of protein, carbohydrate, fat, and other nutrients used in the body of an organism to sustain growth and vital processes and to furnish energy.
The absorption and utilization of food by the body is fundamental to nutrition and is facilitated by digestion.
Plants, which convert solar energy to food by photosynthesis, are the primary food source.
Animals that feed on plants often serve as sources of food for other animals.
What is Fuel?Fuel is a substance that is burned to provide nuclear energy, heat or power.
Materials like coal, wood, oil, or gas can provide heat when burned. Methanol, Gasoline, Diesel, Propane, Natural gas, Hydrogen are types of fuel. Nuclear energy is produced by burning plutonium.
From fuel efficiency or fuel economy, we can measure how long any vehicle could travel, which is the opposite of fuel consumption.
Fuel consumption is the amount of fuel vehicle uses to travel a particular distance.
Fuel efficiency can be measured in kilometers per liter. The efficiency with which the fuel does a conversion of energy is known as fuel efficiency.
