The document outlines the biology curriculum for Senior 3 students at Colegio Las Cumbres. It includes 3 content areas over the school year: 1) The organization of life and the organism, covering characteristics of living things, cell structure and organization, levels of organization, and movement into and out of cells. Students will make biological drawings and study osmosis in potato strips. 2) Nutrition in humans, including enzymes, the human diet, digestion, and deficiency diseases. Students will study the effect of temperature and pH on enzyme activity. 3) Maintenance of organisms, covering transport systems in the human body like circulation and respiration, the structures and functions of the heart and blood vessels, and
