This official Life and Earth Sciences (SVT) examination paper from the EEHB Baccalaureate 2022 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 fundamental topics: neurophysiology (action potential propagation in a neuron), immunology (self-expression), energy resources (renewable and non-renewable energy), and genetics (meiotic division and gametogenesis). A document analysis exercise then addresses renal physiology and blood pressure regulation, analyzing the effects of hemorrhage on urinary output.

The practical skills assessment includes two molecular biology exercises. The first covers the architectural organization of nucleic acids, DNA structure (nucleotides, nitrogenous bases), and building a DNA molecule model. The second exercise deals with protein biosynthesis, requiring candidates to identify and locate the stages of transcription and translation, as well as the molecular actors involved (RNA polymerase, mRNA, ribosomes, amino acids).

Part B evaluates competencies through a problem-based scenario centered on improving seasonal fruit preservation. Candidates must:

• Describe mango transformation and preservation techniques (juice, nectar, jam, dried mango)
• Create a poster presenting products derived from mango processing
• Design a slogan highlighting the advantages of seasonal fruit transformation

The complete answer key is included with detailed evaluation grids. This document is an essential preparation tool for Baccalaureate series C and Ti candidates seeking to deepen their knowledge in molecular biology, physiology, and environmental education.
