Bio 213 Final Exam (Liberty University)
Latest Update
Anatomy - ANSWER The scientific discipline that investigates the body's
structures
Physiology - ANSWER the scientific investigation of the processes or functions
of living things
Pathology - ANSWER the medical science dealing with all aspects of diseases
Structural organization levels - ANSWER 1. Chemical
2. Cellular
3. tissues
4. organ
5. organ system
6. organism
Homeostasis - ANSWER The existence and maintenance of a relatively constant
environment within the body
Negative feedback - ANSWER When any deviation from he set point is made
smaller (the body is correcting the change)
Positive feedback - ANSWER When a response to the original stimulus results in
the deviation form the set point becoming even greater
Covalent bond - ANSWER When atoms share 1 or more electrons
Ionic bond - ANSWER A complete transfer of electrons between two atoms
results in separate positively charged and negatively charged ions.
Polar Covalent bond - ANSWER An unequal sharing of electrons between two
atoms results in a slightly positive charge on one side of the molecule and a
slightly negative charge on the other side of the molecule.
Non-polar Covalent bond - ANSWER An equal sharing of electrons between two
atoms results in an even charge distribution among the atoms of the molecule
Hydrogen Bond - ANSWER The attraction of oppositely charged ends of one
polar molecule to another polar molecule holds molecules or parts of molecules
together.
, Carbohydrate Monomer - ANSWER Monosaccaride
Lipid Monomer - ANSWER Fatty Acid
Protein Monomer - ANSWER Amino Acid
Nucleic Acid Monomer - ANSWER Nucleotide
Carbohydrate Function and Composition - ANSWER Function: Structure (for
DNA), Energy, Bulk (found in feces)
Composition: carbon, hydrogen, and oxygen
Lipids Function and Composition - ANSWER Function: Protection, Insulation,
Regulation, Vitamins, Structure, Energy
Composition: carbon, hydrogen, and oxygen
Protein Function and Composition - ANSWER Function: Regulation, Transport,
Protection, Contraction, Structure, Energy
Composition: carbon, hydrogen, oxygen, and nitrogen
Nucleic Acid Function and Composition - ANSWER Function: makes up DNA and
RNA
Composition: carbon, hydrogen, oxygen, nitrogen, and phosphorus
ATP - ANSWER important to storing and providing energy to all living organisms
Function of the Cell - ANSWER Metabolism, synthesis, communication,
reproduction
Plasma membrane function - ANSWER Separation, regulation, communication,
and structure
(Outside of the membrane is positive, and the inside of the membrane is
negative)
Phospholipid bilayer - ANSWER Polar heads face towards the outside, and the
non-polar heads face each other
Channel Proteins - ANSWER One or more integral membrane proteins arranged
so that they form a tiny channel through the plasma membrane
ATP powered pump - ANSWER ATP-powered pumps move specific ions or
molecules across the membrane using ATP to provide energy. Move specific
ions or molecules across the membrane; require ATP molecules to function
