Bacteria - ANSWER-The most diverse and widespread prokaryotes.
Archaea - ANSWER-Are prokaryotes that often live in earths extreme environment.
Eukarya - ANSWER-Have eukaryotic cells and include fungi, animals, and plants.
What is a element? - ANSWER-Is a substance that cannot be broken down into
other substances.
4 elements that make up most of living organisms are - ANSWER-Oxygen, carbon,
hydrogen, and nitrogen.
What is a compound? - ANSWER-It is a substance consisting of 2 or more different
elements into a fixed ratio.
What is an atom? - ANSWER-It is the smallest unit of matter that still retains the
properties of an element.
Protons - ANSWER-Positive
Electrons - ANSWER-Negative
Neutrons - ANSWER-Neutral
Which out of protons, neutrons, and electrons are involved in a chemical activity? -
ANSWER-Electrons
, What is the electron shell? - ANSWER-Electrons occur in energy levels, 1st energy
shell holds 2, 2nd energy shell hold 8 and the 3rd holds 8.
What happens to atoms with incomplete outer shells? - ANSWER-They may react
with other atoms by sharing, donating, and receiving electrons.
What is a covalent bond? - ANSWER-The strongest kind of chemical bond in which
two atoms share one or more outer shell electrons.
What is a polar covalent bond? - ANSWER-It is where oxygen attracts the shared
electrons more strongly than hydrogen.
What is an ion? - ANSWER-It is an atom or molecule with an electrical charge
resulting from gain or loss of electrons.
When an atom is lost... - ANSWER-A positive charge results.
When an electron is gained... - ANSWER-A negative charge results.
What is an ionic bond? - ANSWER-2 ions with opposite charges attract each other.
A solution is... - ANSWER-A liquid consisting of a uniform mixture of 2 or more
substances.
What is a solvent? - ANSWER-The dissolving agent,
What is a solute? - ANSWER-The substance that is dissolved.
What is an aqueous solution? - ANSWER-is one which the water is the solvent.
A compound that releases hydrogen ions to a solution is a... - ANSWER-Acid

Acidic is... - ANSWER-0-6
Basic is... - ANSWER-8-14
What is acid precipitation? - ANSWER-Rain, snow, or fog that has a pH lower than
5.2.
CO2 dissolving in sea water lowers ocean pH in a process known as... - ANSWER-
Ocean acidification
What is a carbon skeleton? - ANSWER-A chain of carbon atoms that can be
branched or unbranched.
What are the 4 classes of molecules? - ANSWER-Carbohydrates, proteins, lipids,
and nucleic acids.
