The document outlines the content and topics covered in a senior biology class at Colegio Las Cumbres for the 2019 school year. The content is divided into three terms and covers subjects like variation and natural selection, the digestive, circulatory, and excretory systems, evolution, and related lab work. Some of the sub-topics included are genetic and environmental variation, mutation, antibiotic resistance, the structure and function of organs like the kidneys, formation of urine, transport of materials in the blood, and comparing inspired and expired air. Labs will involve experiments on insulation, drawing feathers and teeth, testing for vitamin C, and analyzing food.
