BIOLOGY 111 STUDY EXAMS GUIDE ALL QUESTIONS
AND ANSWERS SURE A+
✔✔photosynthesis - ✔✔process occurring usually within chloroplasts whereby
chlorophyll-containing organelles trap solar energy to reduce carbon dioxide to
carbohydrate.
✔✔hypothesis - ✔✔supposition established by reasoning after consideration of
available evidence; it can be tested by obtaining more data, often by experimentation.
✔✔scientific theory - ✔✔concept supported by a broad range of observations,
experiments, and data.
✔✔Law - ✔✔a term used for theories that are generally accepted by an overwhelming
number of scientists.
✔✔Levels of Classification - ✔✔Domain, Kingdom, Phylum, Class, Order, Family,
Genus, Species
✔✔Levels of Biological Organization - ✔✔Atom, molecule, cell, tissue, organ, organ
system, organism, population, community, ecosystem
, ✔✔Characteristics of Life - ✔✔organized, acquire materials and energy, respond,
reproduce and develop, have adaptations.
✔✔Eukarya Four Kingdoms: - ✔✔Protista, Fungi, Plantae, and Animalia
✔✔experimental variable - ✔✔is the step that is deliberately manipulated. (nitrogen,
fertilizer)
✔✔dependent variable - ✔✔is component of an experiment that changes due to the
experimental variable.
✔✔control variable - ✔✔components that are not changed.
✔✔matter - ✔✔anything that takes up space and has mass.
✔✔element - ✔✔cannot be broken down to simpler substances with different properties.
✔✔protons - ✔✔are positively charged particles (have 1 atomic mass unit of weight).
✔✔neutrons - ✔✔have no charge. (1 atomic mass unit of weight)
✔✔electron - ✔✔are negatively charged particles.
✔✔isotopes - ✔✔are atoms with the same number of protons but differ in number of
neutrons.
✔✔molecule - ✔✔union of two or more atoms of the same element.
✔✔compound - ✔✔two or more different elements react or bond together.
✔✔atomic mass - ✔✔the sum of protons and neutrons.
✔✔atomic number - ✔✔number of protons.
✔✔ionic bond - ✔✔form when electrons are transferred from one atom to another.
✔✔covalent bond - ✔✔form when two atoms share electrons
✔✔nonpolar covalent bonds - ✔✔sharing of electrons is equal.
✔✔polar covalent bonds - ✔✔sharing of electrons is unequal.
