ANATOMY AND PHYSIOLOGY CHAMBERLAIN BIO 251 MIDTERM ONE
COMPREHENSIVE TEST PREP | UPDATED FOR 2025–2026
Water - correct answer -an absorbent polar covalent molecule that serves as a solvent, has a
high heat capacity, creates a high surface tension, and serves as lubricant
Acid - correct answer -a substance that dissociates intone or more hydrogen ions and one or
more anions
Save
Salt - correct answer -a substance that dissacociates into cations and anions, neither of which is
hydroxide ion
Base - correct answer -a proton acceptor
PH - correct answer -a measure of hydrogen ion concentration
Buffer - correct answer -a chemical compound that can convert strong acids and basses into
weak ones
Enzyme - correct answer -a catalyst for chemical reactions that is specific, effective,and under
cellular control
RNA - correct answer -a single-stranded compound that contains a five carbon sugar base
adenine, cytosine, guanine,uracil
, ATP - correct answer -a compound that functions to temporarily store and then transfer energy
liberated in exergonic reactions to cellar activities that require energy
DNA - correct answer -a double stranded compound that contains a five carbon sugar adenine,
thymine,cytosine,guanine and the body genetic material
Ion - correct answer -a charged atom
Fee Radical - correct answer -a charged atom with an unpaired electron in its outermost shell
Mitosis - correct answer -somatic cell division resulting in two daughter cells
Meiosis - correct answer -reproductive cell division that reduces the number of chromosomes
by half
Prophase - correct answer -stage when chromatin fibers condense and shorten to form
chromosomes
Metaphase - correct answer -stage when centromeres of chromatid pairs line up at the center
the mitotic
Anaphase - correct answer -stage when centromeres split and chromatids move to opposite
poles of the cell
Telophase - correct answer -stage when chromosomes uncoil and revert to chromatin
Cytoskeleton - correct answer -network of protein filament that extend throughout the
cytoplasm, providing cellular shape, organization, and movement
