Four primary regions are the brainstem, the cerebellum, the cerebrum, and the cerebral cortex. Each brain region is responsible for a variety of functions, and injury to any of these regions impairs specific functions.
Cellular respiration is a pathway that organisms use to generate energy. Oxygen is required and is used to break down nutrients, like glucose sugar. The nutrients are broken down to generate ATP (energy) and carbon dioxide and water (waste). Organisms from all kingdoms of life can use cellular respiration including bacteria, archaea, plants, protists, animals, and fungi.
What types of cells and organisms undergo mitosis and meiosis. Mitiosis undergo cells and organisms that can reproduce asexually and create indentical copies of their DNA. Meiosis uses organisms that rely on sexual reproduction however the process of mitosis is still needed for growth.
