This official Life and Earth Sciences (SVT) examination paper from the EEHB Baccalaureate 2024 session is a comprehensive document containing both the exam questions and detailed answer key. It is organized in two parts evaluating candidates' resources and competencies.
Part A begins with knowledge assessment through an MCQ exercise covering four domains: immunology (autoimmune diseases: vitiligo, juvenile diabetes, myasthenia gravis), genetics (types of gene and chromosomal mutations), natural disasters (distinguishing natural from anthropogenic origins), and metabolic regulation (roles of insulin and glucagon after a carbohydrate-rich meal). A document analysis exercise addresses cell biology with the study of osmosis through red blood cell behavior in different NaCl solutions (plasmolysis, turgescence, hemolysis).
The practical skills assessment includes two exercises. The first covers experimental immunology: determining the sites of formation and maturation of immune cells through irradiation experiments, bone marrow grafts, and thymus removal in mice. The second exercise addresses human genetics with the analysis of a family tree illustrating gonosomal inheritance (X-linked), applied to a blood clotting deficiency.
Part B evaluates competencies through a problem-based scenario on combating metabolic diseases and immune system disorders. Candidates must:
The complete answer key is included with detailed evaluation grids. This document is an essential tool for Baccalaureate series C and Ti candidates seeking to master immunology, genetics, cell biology, and health education.
