IEOC Biology Content Coverage
Interactive released itemsPrint-ready
The Iowa End-of-Course assessments are designed to assess student knowledge and
skills in a variety of subject areas. The test consists of 30 multiple-choice items
and is designed to be administered during a single class period. The test items,
which are aligned to the Iowa Core Curriculum, reflect educator input and a rigorous
quality-control process to ensure appropriateness, content accuracy, and clarity.
A summary of the content covered within the Biology test is presented below.
Topics may include cell types, cell components and their functions, cell membranes
(absorption and transport), the cell cycle, mitosis, cell differentiation, photosynthesis,
cellular respiration,enzymes as catalysts of biological reactions.
Molecular basis of heredity
Topics may include DNA, RNA, DNA replication, transcription, translation, sexual
reproduction, gametes, meiosis, fertilization, genes, alleles, Mendel’s laws, Punnett
square, genotype, phenotype, and mutations.
Topics may include diversity of organisms, descent from common ancestors, natural
selection, survival and reproductive success, genetic variation, biological classification,
and binomial nomenclature.
Interdependence of organisms/Matter, energy, and organization in living systems
Topics may include cycling of materials, symbiotic interactions, competition, predation,
population, community, food chains, food webs, energy flow through trophic levels,
effects of environmental factors and finite resources, impact of human activities
on ecosystems, the Sun as the primary source of energy for life, energy aspects
of photosynthesis and cellular respiration, ATP, conservation of matter and energy,
and levels of biological organization.
Behavior of organisms
Topics may include nerve cell structure and function, neurotransmitters, CNS and
PNS, ectothermy and endothermy, innate behavior, learning, behavioral responses
to external and internal stimuli, plant behavior, human immune system, and human
