Biology is the science of living things that majorly includes the study of animals, plants and different microorganisms. Unicellular Organisms Many living things are composed of just one cell. Organisms, or the individual entities of life, are generally thought to be open systems that maintain homeostasis, are composed of cells, have a life cycle, undergo metabolism, can grow, adapt to their environment, respond to stimuli, reproduce and evolve over multiple generations. Fungi have well-defined characteristics that set them apart from other organisms. Nutrition is the process by Example of the living thing is a dog.

It cant distinguish between its own mRNA and the RNA introduced into the cell by the virus. What this means is that changes in the environment trigger certain responses in organisms. Technically, yes. Earthworms use circular and longitudinal muscles to move through soil or along surfaces. In addition, they are autotrophic organisms, which means that they create their own food through the photosynthesis . Cellular organization refers to all the components of the cell and how they are arranged.
