IO 1400 Final Exam 2026 – 120 Questions & Verified Answers – Cell Biology, Genetics, Evolution & Ecology

This document contains 120 comprehensive exam questions and verified answers for the BIO 1400 Final Exam 2026. It thoroughly reviews core biological concepts including cell structure and function (mitochondria, nucleus, ribosomes, cell wall), cellular respiration and oxidative phosphorylation, DNA structure and replication, transcription and translation, PCR, gene therapy, Mendelian inheritance, Punnett squares, and mutation types. The material also provides in-depth coverage of evolutionary mechanisms (natural selection, sexual selection, artificial selection, gene flow, convergent evolution, antagonistic coevolution, Red Queen hypothesis), population genetics, reproductive barriers (prezygotic and postzygotic), and ecological principles such as trophic levels, food webs, energy pyramids, succession, carbon cycle, carbon sinks, greenhouse effect, climate vs. weather, convection cells, and ecosystem dynamics. It integrates foundational scientific reasoning concepts including hypothesis testing, statistical significance (p-values), independent validation, and experimental design. This study guide is particularly suitable for: BIO 1400 students General Biology I students Pre-med and pre-health majors Nursing and allied health students Environmental science students Biology majors preparing for cumulative finals It is relevant for courses such as: General Biology I Introduction to Biology Cell and Molecular Biology Genetics Evolutionary Biology Ecology and Environmental Science The structured question-and-answer format makes this resource ideal for cumulative final exam review, concept reinforcement, and preparation for multiple-choice and short-answer assessments. It supports mastery of essential biological principles spanning molecular biology to ecosystem-level processes.
