Biology 1 Midterm Review Question
and answers rated A+ 2025/2026
Acid - correct answer ✔compound that forms hydrogen ions in a solution; a solution with a pH of less
than 7
Base - correct answer ✔compound that produces hydroxide ions in solution; solution with a pH of 7 or
more
Aerobic Respiration - correct answer ✔process that requires oxygen
Anaerobic - correct answer ✔process that does not require oxygen
Atom - correct answer ✔the basic unit of matter
ATP Synthase - correct answer ✔a cluster of proteins that span the cell membrane and allow hydrogen
ions to pass through it
Carbohydrates - correct answer ✔compounds made of hydrogen, oxygen, and carbon; plants and
animals use it for structural purposes
Lipids - correct answer ✔used to store energy
Cell Membrane - correct answer ✔surrounds the cell with a flexible barrier sometimes called the
plasma membrane because many cells in the body are in direct contact with the fluid portion of the
blood plasma
Chemical Changes - correct answer ✔burn, rust, tarnish, cook denture
, Physical Changes - correct answer ✔evaporation, freezing, melting, cutting, shape, sort, condense
Chromosome Theory of Inheritance - correct answer ✔chromosomes are a linear sequence,
inheritance patterns may be generally explained by assuming that genes are located in specific sites on
chromosomes
Chromosomes - correct answer ✔threadlike structure within the nucleus that contains genetic
information that is passed from one generation to the next
Gene - correct answer ✔sequence of DNA that codes for a protein and thus determines a trait; factor
that is passed from one parent to offspring
Coenzymes - correct answer ✔a molecule that provides the transfer site for biochemical reactions
catalyzed by an enzyme
Convert within the metric system - correct answer ✔KHDBDCM (each unit is 10x larger or smaller than
the next)
Dehydration - correct answer ✔an abnormal loss of water from the body, especially from illness or
physical exertion
Hydrolysis - correct answer ✔chemical decomposition in which a compound is split into other
compounds by reacting with water
Gamete Cells vs. Regular Cells - correct answer ✔Gemete: sex cells
Sexual Reproduction - correct answer ✔cells from two parents untie to form the first of a new
organism
