CSEC Human and Social Biology study guide
CSEC Human and Social Biology · Work through your exam, one topic at a time.
CSEC Human and Social Biology is a Caribbean Examinations Council (CXC) subject examination at the CSEC level. According to CXC, the syllabus is designed to develop students' understanding of the structure and function of the human body, the interdependence of living things, and the interaction between human health and the environment. It emphasises practical application of biological principles to health maintenance and healthy living, and builds awareness of the socio-cultural and commercial determinants of disease prevention and control. The course suits students aiming at careers in allied health (nursing, medical technology, pharmacy), physical education and sports science, health education, nutrition and dietetics, social work and community health, environmental health, or public health and health promotion, and gives a foundation in human biology and health science for further study. Topics on this exam: Organisms and Metabolism, Life Processes, and Heredity, Diseases and the Environment. The CSEC Human and Social Biology study guide has 3 sections and about 2,001 words.
01Organisms and Metabolism
Organisms and Metabolism tests how cells are built, how substances cross membranes, how enzymes control reactions, and how organisms obtain and release energy through photosynthesis, respiration, digestion and diet. Expect questions that ask you to explain observations and to name the correct enzyme, test or deficiency disease, not just to label a diagram.
555 words, about 3 min02Life Processes
Life Processes tests transport, gaseous exchange, excretion and homeostasis, support and movement, and reproduction - the systems that keep a multicellular body working. Questions often ask you to link structure to function and to explain a change using negative feedback.
508 words, about 3 min03Heredity
Heredity tests how genetic information is stored, copied, divided and passed on, and how that produces variation. You should be able to follow a monohybrid cross, use genetic terms precisely, and explain sex determination and common genetic disorders.
