OSAT Biological Sciences (110) study guide
OSAT Biological Sciences (110) · Work through your exam, one topic at a time.
Biological Sciences (110) is one of the subject-area tests in the Certification Examinations for Oklahoma Educators (CEOE) program, the assessment system Oklahoma uses for educator certification. Candidates typically take it to demonstrate biology content knowledge for a teaching credential in the state; the test is listed among the CEOE tests on the official program website, and registration opened for it on 8/29/23. The exam is organized around four equally weighted content domains - Foundations of Biological Science, Molecular and Cellular Biology, Genetics and Evolution, and Organismal Biology and Ecology - each accounting for 25 percent of the score. That balance matters for study planning: many candidates over-prepare cell and molecular material and under-prepare ecology and organismal content. The OSAT Biological Sciences (110) study guide has 4 sections and about 1,385 words.
01Foundations of Biological Science
This domain tests how biological knowledge is built and the chemical and physical rules that underlie life: scientific inquiry and experimental design, measurement and microscopy, lab safety, water and pH, and the structure and function of biological macromolecules. Questions often ask you to identify variables, evaluate a conclusion, or predict a chemical property.
375 words, about 2 min02Molecular and Cellular Biology
This domain tests cell structure and function, membrane transport, energy transformation, and the flow of genetic information. Expect questions that compare prokaryotic and eukaryotic cells, predict the direction of osmosis, trace ATP production, or identify where transcription and translation occur.
348 words, about 2 min03Genetics and Evolution
This domain tests inheritance, molecular genetics, and evolutionary mechanisms. Questions ask you to predict offspring ratios, interpret pedigrees, calculate allele frequencies, distinguish mutation from selection, and explain how reproductive isolation produces species.
330 words, about 2 min04Organismal Biology and Ecology
This domain tests how whole organisms maintain homeostasis and how populations and ecosystems function. Expect questions on plant and animal transport, feedback, energy flow, population growth, species interactions, and nutrient cycles.
