HiSET prep Science A-C Exam 2025
Questions and Answers
Acceleration - ANSWER✔✔-The change in velocity resulting from a net force being
applied to an object.
Adaption - ANSWER✔✔-The response to environmental change by a species, the
physical change in a species over time in ways that make survival more likely in a given
environment.
Aerobic - ANSWER✔✔-Containing oxygen; referring to an organism, environment, or
cellular process that requires oxygen.
Allele - ANSWER✔✔-Individual units of genetic information the define the inheritance
of traits.
Anerobic - ANSWER✔✔-Lacking oxygen; referring to an organism, environment, or
cellular process that lacks oxygen and may be poisoned by it.
Assoiciation - ANSWER✔✔-Another word for correlation. Describes the relationship
between two variables in a data set.
, Atom - ANSWER✔✔-The fundamental unit that makes up the physical material-matter
in our natural world. Atoms are made up of three particles: protons, neutrons and
electrons. Protons and neutrons make up the nucleus of the atom, and the electrons
orbit the nucleus in rings called shells. Protons have a positivie electrical charge.
Neutron s have no elelctrical charge. Electrons have a negetive electrical charge.
Atomic number - ANSWER✔✔-The number of protons in an atom's nucleus.
ATP - ANSWER✔✔-A form of chemical energy used in cellular functions.
Base - ANSWER✔✔-A compound of DNA whose sequence on a strand defines the
genetic code of an organism. Bases provide the mechanism fro two DNA strands to join
together.
Bias - ANSWER✔✔-Accidental discrimination in experimental design that affects the
quality of the results.
Big Bang - ANSWER✔✔-A theoretical giant explosion throught to have created the
universe.
Bonds - ANSWER✔✔-Connections between atoms, used to form compounds and
molecules.
Carbon - ANSWER✔✔-A chemical element. The symbol for carbon is C.
Carbon dioxide - ANSWER✔✔-A molecule consisting of 1 carbon and 2 oxygen atoms;
a very important factor in global warming.
