Common questions on biology exams ask students about cell shape and function; bacteria identification, bacterial growth characteristics and identification; viruses; and DNA sequencing, mutation and repair. Other common questions ask students to identify the name and function of each part of an organism, to differentiate between gram-positive and gram-negative cells, and to describe the functions of amino peptides and amino acids.
Basic functions of the human body, abnormalities and physiological responses are common categories on biology quizzes. Questions in these areas commonly ask about diseases and immune responses, including contracted diseases, genetic disorders, cell destruction and regeneration. Autoimmune disorders and microbial metabolism are also common human body topics on biology quizzes.
In addition to biology of the body, questions on biology quizzes also include those relating to household air and the surface dangers of bacteria, mold, mildew and viruses; the environmental biology of soils, waste water, animals, plants, and aquatic environments, such as streams, creeks, lakes, rivers and ponds; the types of bacteria that breed in food and beverages; and the structure and impact of chemical agents.
Biology quizzes typically consist of multiple-choice questions, true-or-false questions, and identifying diagrams. Essay questions are not typically included, except under comparison conditions, or when a question asks a student to compare processes or explain a function, cause or outcome.
