Prepare for the Admission Test for Dental Hygiene (ATDH) with this comprehensive ATDH Biology Study Guide featuring Practice Questions, Verified Answers, and Detailed Rationales. Designed specifically for aspiring dental hygiene students, this resource provides focused review of the biology concepts most commonly assessed on the ATDH examination. The Biology section of the ATDH evaluates foundational scientific knowledge, critical thinking, and the ability to apply biological principles in healthcare-related contexts. This complete study guide covers essential topics including cell biology, biomolecules, cellular respiration, photosynthesis, genetics, heredity, evolution, ecology, human body systems, homeostasis, microbiology, molecular biology, DNA structure and function, protein synthesis, metabolism, biological diversity, and organismal physiology. These core concepts align with the biology competencies expected of candidates entering accredited dental hygiene programs. Included are comprehensive practice questions, detailed answer explanations, exam-style assessments, and high-yield review materials designed to strengthen knowledge retention and improve test-taking confidence. The guide emphasizes concept application and scientific reasoning while helping students identify strengths and areas requiring additional review. Ideal for first-time ATDH candidates, pre-dental hygiene students, and applicants seeking competitive admission scores. Updated for 2026/2027 admission testing standards, this resource supports efficient preparation through structured content review and targeted practice.

Abiotic factors nonliving parts of an ecosystem

Substances travel against their concentration
Active transport gradient and require consumption of energy by
carrier proteins

Aerobic cellular Breaking down carbohydrates for energy (consumes
respiration oxygen, more energy produced)

Uses the 2 NADH from glycolysis to convert the 2
Alcohol fermentation
pyruvate into 2 ethanol

Allele One variation of a gene

Amino acids building blocks of proteins

Involve using energy to build larger
Anabolic
macromolecules

Anaerobic cellular Breaking down carbohydrates for energy (no
respiration oxygen needed, but less energy produced)

kingdom of multicellular eukaryotic heterotrophs
Animalia
whose cells do not have cell walls

, known as protozoa, have food vacuoles. Include
Animal-like protists amoeba and paramecium. Heterotrophic (move via
flagella and cilia) and often parasitic pathogens.

Apparent competition Occurs when one predator preys on two species

Cell wall lacks peptidoglycan, lipids bound via
Archaea ether-linkages
Extremophiles: able to survive harsh environments

used as the cellular energy currency because of the
ATP
high energy bonds between the phosphate groups

A channel protein that provides a hydrophilic tunnel
ATP synthase to allow protons to flow down their electrochemical
gradient

The breakdown of the cell's own machinery for
Autophagy
recycling

Autosomes 22 pairs in the human body; nonsex chromosomes

Autotrophs Make their own food

, Organisms will replicate their genome while cell
Binary fission
division is happening

All ecosystems on earth, their interactions with each
Biosphere other and the lithosphere, geosphere, hydrosphere,
atmospher

Biotic factors Living elements of an ecosystem

light-dependent reactions of photosynthesis in
Calvin cycle which energy from ATP and NADPH is used to build
high-energy compounds such as sugar

Capillary action an adhesive force pulls water column upward

contain carbon, hydrogen, and oxygen
Carbohydrates Come in forms of monosaccharides, disaccharides,
and polysaccharides

Process by which inorganic carbon is converted into
Carbon fixation
an organic molecule
