Atom - Answer tiny particles that make up chemicals (hydrogen, carbon)
Molecule - Answer particles consisting of atoms joined together (water, glucose)
Macromolecule - Answer large particles consisting of molecules (D N A, protein)
Organelle - Answer functional part of a cell (mitochondrion, lysosome)
Cell - Answer basic unit of structure and functions (muscle, nerve, or blood cell)
Tissue - Answer layer or mass of cells with specific function (adipose tissue)
Organ - Answer group of different tissues with a function (heart, kidney, stomach)
Organ System - Answer group of organs with common function (digestive system)
Organism - Answer composed of organ systems interacting (human)
Movement - Answer Change in position of the body or of a body part; motion of an internal
organ.
Responsiveness - Answer Reaction to a change inside or outside the body.
Growth - Answer Increase in body size without change in shape.
Reproduction - Answer Production of new organisms and new cells.
,Respiration - Answer Obtaining oxygen, removing carbon dioxide, and releasing energy from
foods (some forms of life do not use oxygen in respiration)
Digestion - Answer Breakdown of food substances into simpler forms that can be absorbed
and used.
Absorption - Answer Passage of substances through membranes and into body fluids
Circulation - Answer Movement of substances in body fluids
Assimilation - Answer Changing of absorbed substances into different chemical forms
Excretion - Answer Removal of waste produced by metabolic reactions.
3. What are the requirements of life? Why is each important? - Answer Oxygen, Gas,
Pressure, Water and Food.
Homeostasis - Answer the maintenance of a stable internal environment
Homeostatic Mechanism - Answer Self-regulating systems that monitor aspects of the
internal environment and correct them as needed.
Matter - Answer Anything that takes up space and has mass. Matter is composed of
elements. Solids, liquids, and gases are matter.
Element - Answer Simplest types of matter with certain chemical properties. There are 98
naturally occurring elements.
Atom - Answer Smallest particles of an element that have properties of that element.
The basic unit of matter is the Atom.
Atom - Answer Composed of subatomic particles
Proton - Answer Carries a single positive charge
Neutrons - Answer carries no electrical charge
, Electron - Answer Carries a single negative charge
Nucleus - Answer Central part of atom, Composed of protons and neutrons, Electrons move
around the nucleus
1. Define nucleus, proton, neutron and electron. What charges do each of these particles have?
- Answer The nucleus is the center of the atom. Proton is positive, Electron is Negative and
Neutrons are no charge. Proton and Neutrons are in the center of the nucleus. The electrons are
in the otter electron shell.
Covalent Bond - Answer Strong chemical bonds, formed between atoms that share
electrons.
Ionic Bonds - Answer Formed when electrons are transferred from one atom to another
atom
The attraction between a cation and an anion forms a very strong bond between the ions
Hydrogen Bonds - Answer · A weak attraction between the slightly positive (H) end of one
polar molecule and the slightly negative (N or O) end of another polar molecule.
· Formed between adjacent water molecules.
Important for protein and nucleic acid structure.
Synthesis Reaction - Answer more complex chemical structure is formed.
A+B——> AB
Decomposition Reaction - Answer chemical bonds are broken to form a simpler chemical
structure.
AB ——> A+B
Exchange Reaction - Answer chemical bonds are broken and new bonds are formed.
AB+CD—> AD+CB
Reactant - Answer the starting materials of a chemical reaction: the atoms, ions, or
molecules.
· NaCl
Products - Answer substances formed at the end of the chemical reaction.
