STAAR BIOLOGY UPDATED ACTUAL
Exam Questions and CORRECT Answers
Active Transport - CORRECT ANSWER - Molecules move AGAINST concentration
gradient from low to high concentration using ATP
Adaptation - CORRECT ANSWER - a trait which gives an organism a higher chance of
survival in its environment
Analogous Structures - CORRECT ANSWER - structures with similar function that vary
in structure (ex: wing of fly and bird)
anaphase - CORRECT ANSWER - third phase of mitosis where sister chromatids are
separated
archaebacteria - CORRECT ANSWER - kingdom of bacteria which live in extreme/harsh
environments (ex: methanogens)
binomial nomenclature - CORRECT ANSWER - the two-word naming system that
includes the genus and species
biology - CORRECT ANSWER - the study of life and living organisms
biomolecules - CORRECT ANSWER - large molecule present in organisms that contain
carbon (lipids, carbohydrates, proteins, nucleic acids)
cancer - CORRECT ANSWER - unregulated/uncontrolled cell division; creates tumors
capsid - CORRECT ANSWER - the outer protein shell of a virus
, carbohydrate - CORRECT ANSWER - biomolecule used for fast energy and plant
structure, contains CHO
cell cycle - CORRECT ANSWER - the process in which the cell grows, replicates DNA,
and divides to form daughter cells
cell differentiation - CORRECT ANSWER - specialization of cells for a particular
function
cell membrane - CORRECT ANSWER - same thing as plasma membrane; surrounds the
cell and maintains homeostasis by controlling what enters/exits the cell
cell wall - CORRECT ANSWER - surrounds the cell membrane; supports and protects
plant cells; NOT the same as cell membrane
cellular respiration - CORRECT ANSWER - the process of making energy from glucose;
occurs in mitochondria
channel proteins - CORRECT ANSWER - embedded in the cell membrane and move
materials across the cell membrane (facilitated diffusion)
chloroplast - CORRECT ANSWER - plant cell organelle where photosynthesis occurs
chromosomal analysis - CORRECT ANSWER - the detailed study of all the chromosomes
of a cell
chromosomal mutation - CORRECT ANSWER - involves changes to the structure or
organization of a chromosome
chromosome - CORRECT ANSWER - x-shaped structures of DNA
