HESI A2 Biology Version 2 2026 | 100+ Exam Questions & Correct Answers | Cell Biology, Genetics, Photosynthesis, Homeostasis & Nursing Entrance Exam

Prepare for the HESI A2 Biology Version 2 examination with this comprehensive study guide featuring 100+ exam-style questions, verified answers, and high-yield biology review covering the most frequently tested concepts on the HESI Admission Assessment Exam. This resource provides focused practice in cell biology, prokaryotic and eukaryotic cells, metabolism, photosynthesis, cellular respiration, mitosis, meiosis, DNA replication, transcription, genetics, Punnett squares, dominant and recessive alleles, osmosis, passive transport, homeostasis, enzymes, macromolecules, immune system function, tissue types, and cellular processes. The questions are structured to closely reflect the format, content, and level of difficulty of the official HESI A2 Biology examination, making this an excellent resource for targeted review and exam preparation. The study guide reinforces essential biological concepts through active recall and exam-focused practice while strengthening foundational knowledge required for nursing and allied health admissions. Students will review cell structure and function, membrane transport mechanisms, protein synthesis, DNA and RNA, chromosome inheritance, photosynthesis, cellular energy production, enzyme activity, diffusion and osmosis, isotonic and hypertonic solutions, connective and epithelial tissues, muscular tissue, immune responses, homeostasis, metabolism, and biological macromolecules including carbohydrates, lipids, proteins, and nucleic acids. Each question is paired with the correct answer to improve knowledge retention, critical thinking, and confidence when completing standardized nursing entrance examinations. Designed specifically for nursing school applicants and healthcare students, this study guide serves as an effective review resource for first-time HESI A2 candidates and repeat examinees seeking higher biology scores. The organized question-and-answer format supports independent study, classroom review, and final exam preparation while helping students master the core biological principles assessed on the HESI Admission Assessment Exam.
