LIFE SCIENCE

Detailed explanation-1: -The bodies of organisms are organized into functional systems-cells are organized into tissues, and tissues are organized into organs. Body systems carry out critical functions, such as locomotion, reproduction, digestion, and circulation.

Detailed explanation-2: -The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

Detailed explanation-3: -Organs are structures made up of two or more tissues organized to carry out a particular function, and groups of organs with related functions make up the different organ systems.

Detailed explanation-4: -For efficient performance, many cell organization comes together to form tissues. A group of tissues, similar cells, and similar structures together form an organ. The physiological processes of the group of organs are called organ systems, and many organ systems together form an organism.

Detailed explanation-5: -Cells are the basic structures of all living organisms. Cells provide structure for the body, take in nutrients from food and carry out important functions. Cells group together to form tissues?, which in turn group together to form organs?, such as the heart and brain.
