Explanation: Most Archaeas don't have membrane-bound organelles, they are mostly unicellular prokaryotic organisms.
Archaea are found living alongside bacteria in many environments. Recently Archaea belongs to Crenarchaeota have been implicated in nitrogen cycling in the soil.
Fungi are eukaryotic multicellular organisms and they have membrane-bound organelles. they are hence more closely related to plants and animals than to bacteria or archaea. Like eukaryotes, Fungi has nuclei with chromosomes that contain DNA. They possess membrane-bound organelles such as mitochondria. Fungi are heterotrophs, and they are saprophytic, they feed on decaying matter. some fungi occur as unicellular organisms, they are generally referred to as yeasts.
Skinner box provides an experimental condition that is used for examining natural flow of the behavior. It is also known with the other name as Operant conditioning chamber. It is a small chamber in which the animals for research are kept. Within the chamber there is a lever or key that the organisms under research can operate in order to get food or water in the chamber. An electronic equipment is connected to the chamber which records the activities of animals on keys or lever.
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
