and Answers Graded A+
Pathology The study of the progression and effects of disease within an organism (what
happens when the body gets the disease)
Pathologist Person that studies pathology
Epidemiology The study of the transmission of disease between organisms (how the
disease gets from one place to another)
Epidemiologist Person that studies epidemiology

A. Universal(ish) solvent
B. Water molecules are cohesive - they stick to each other
C. Excellent thermal sink - H2O has a high heat capacity; 2x > air mass
D. Stays liquid within wide range temps. - 32*-221*F; 0*-100*C Why is water required
for life?
Metabolism Process of extracting and transforming energy
E.g., digestion, assimilation
Energy The capacity to do work
Work A change in motion of matter (move stuff)
, Anabolic Metabolism Synthesis of larger molecules from smaller
Catabolic Metabolism Reduction of larger molecules into smaller
Minerals, sugars What is an example of absorption from environment?
Individual level of environmental interaction/adaption Irritability (reaction to stimuli)
homeostasis. sweating, shivering
Species level of environmental interaction/adaption Evolution of new forms (if you cannot
evolve, species disappears)
Movement Either internal or external
Chemical Uniquness Life forms produce macromolecules (greater than, or equal to, 20 C
atoms)
