Biology EOC study guide Questions
and Answers 100% Pass
What is the study of Biology? - ✔✔The science that seeks to understand the living
world. Studies molecules, cells, organisms, populations of a single organism,
communities of populations living in the same area, and the biosphere.
Contrast unicellular and multicellular organisms. - ✔✔Unicellular only consists of a
single cell, and multicellular organisms consist of many cells.
What is homeostasis? Give an example. - ✔✔Homeostasis is the process by which
organisms maintain a relatively stable internal environment. Example: regulating body
temperature.
What are the main characteristics of life? - ✔✔The main characteristics of life include:
living things are made up of cells, living things reproduce, living things are based on a
universal genetic code, living things grow and develop, living things use energy
(metabolism), living things respond to their environment, living things maintain a
stable internal environment, and living things change over time (groups change).

, What are the steps of a scientific method? - ✔✔State the problem, research, form a
hypothesis, experiment using variables, collect data, derive a conclusion.
How do scientists use the scientific method? - ✔✔Scientists follow the scientific method
in all experiments performed to ensure proper results and data.
What are the purposes of using microscopes in science? - ✔✔Microscopes aid in
magnifying images of structures that are too small to see with the unaided eye.
What is an element? - ✔✔An element is a substance consisting entirely of one type of
atom.
What is an atom? - ✔✔An atom is the basic unit of matter.
What is a molecule? - ✔✔A molecule is the smallest unit of compounds.
What is a compound? - ✔✔A compound is a substance formed by the chemical
combination of two or more elements in definite proportions.
Describe the atomic structure of an atom. - ✔✔An atom consists of protons, neutrons,
and electrons. The protons(+) and neutrons (neutral) are formed in the nucleus. The
electrons (-) orbit, or move around, the nucleus. The atomic number on the periodic
table is determined by the number of PROTONS present.
Describe the different types of atomic bonding (covalent, ionic, hydrogen) -
✔✔Covalent bonds form when electrons are shared between atoms. Ionic bonds form
