AFOQT General Science Information questions and
answers with solutions 2025
biology - ANSWER the study of living things
botany - ANSWER the study of plants
zoology - ANSWER the study of animals
earth science - ANSWER covers conditions affecting the earth (weather, climate, the relationship
of people to their environment)
chemistry - ANSWER a physical science dealing with the composition, structure, and properties
of matter; it's also concerned with changes in matter and the energy released during those
changes
physics - ANSWER a physical science that deals with matter and energy. Gives more attention to
mechanical and electrical forces in areas such as light, sounds, heat, motion, and magnetism
the scientific method - ANSWER 1. Observation
2. Hypothesis
3. Experiment
4. Theory
5. Principle or Law
observations - ANSWER require the accurate viewing and recording of a particular occurrence.
The accuracy of one observation or a set of observations is validated or proved when
independent observers agree that they see the same set of circumstances, achieve the same
experimental results, and so on.
, Hypothesis - ANSWER a temporary or working conclusions based on a set of observations. A
general statement about why the scientist thinks something happens in the way it does. It
usually suggests the need for a particular experiment
Experiment - ANSWER scientists perform experiments to test a specific hypothesis. Reliable
experiments require controlled conditions and careful recording of data.
Theory - ANSWER a hypothesis becomes a theory when it is supported by one or more
experiments; the original hypothesis is usually modified somewhat based on experimental data
before it is acknowledged as a theory.
principle or law - ANSWER when a theory is repeatedly confirmed over a long period of time by
multiple experiments.
homeostasis - ANSWER the balanced internal situation of a cell and the organism as a whole; to
stay alive and healthy, cells have to regulate their external and internal fluids based on
temperature, acid/base balance, and the amount and type of a number of critical substances
All living species have certain characteristics in common - ANSWER 1. All living cells come from
pre-existing living cells
2. All cells make and use enzymes, which are substances that start or speed up chemical
reactions without themselves being affected or changes
3. The heredity or genetic information of all cells is carried by DNA (deoxyribonucleitic acid)
molecules that give cells the ability to reproduce or replicate. DNA make up genes contained in
chromosomes, small rod shaped bodies within a cell that control the characteristics that
offspring receive from their parents
4. Metabolism refers to the biochemical activities necessary for life carried on by all cells,
tissues, organs, and systems
5. A trait or characteristic that lends itself to the survival of an individual or a species is called
adaptation
