2026 Biology STAAR Test Solutions and Explanations

Review your responses for accuracy by comparing them with the solutions provided below. For example, when a question addresses the concept of cellular respiration, make sure to include all key steps such as glycolysis, the Krebs cycle, and the electron transport chain in your answer.

Next, focus on questions related to genetics. Ensure that you correctly apply Mendelian laws when solving problems on inheritance patterns. For example, when given a monohybrid cross, be sure to list all possible genotypes and phenotypes according to Punnett square predictions.

Finally, double-check your understanding of ecological concepts. Questions related to food webs and energy flow should accurately reflect how energy is transferred through trophic levels, from producers to apex predators. Ensure that all key interactions are represented in your diagrams and explanations.
