Structural Hierarchy
What is the relationship between form and function?
Form follows function. How something is designed to work relates to the shape of it.
How much of the body is composed of water?
50-70%
Define Homeostasis.
Keeping physiological conditions within a narrow range for health and stabililty.
What are the 4 major elements in the body?
Oxygen, Carbon, Hydrogen, and Nitrogen.
Is water considered the solvent or solute?
Solvent.
Would Ca^2+ go into the atomic or molecular category?
Atomic
What is oxygen required for to produce?
ATP
An effector can either inhibit or excite. What do those two words mean in the context of the homeostatic control mechanism?
Inhibition: turning off what is causing imbalance
Excitiation: turning on what is causing imbalance
What is the term for a positively charged ion? Negatively charged?
Cation (+)
Anion (-)
When something does not dissolve in H20 it is considered:
hydrophobic.
How would a molecule be defined?
Atoms sharing an energy relationship.
What are the 5 requirements of life?
Oxygen, water, atmospheric pressure, nutrients, and temperature.
What part of the control mechanism determines the Set Point?
Control Center
Is a molecule is nonpolar how would you describe its sharing of electrons?
equal.
What is my major?
Kinesiology
Describe the outcomes to the Human Body Hierarchy if cells were to rapidly reproduce.
This would be cancer. A malfunction would then occur with the tissue level, organs would perhaps then not work properly, organ systems would not, and eventually the whole body would be affected.
What is the difference between catabolism and anabolism?
Catabolism: releases energy after reaction
Anabolism: requires energy for reaction
What is the key difference between neagtive feedback and positive feedback?
Negative feedback has a set end point, while positive feedback does not.
What are the 2 types of reactions created when water is in reactions?
Dehydration Synthesis and Hydrolysis.
What is an example of positive feedback?
Labor or blood clotting
From smallest to largest, name the 7 levels of the Human Body Hierarchy.
atomic, molecular, cellular, tissues, organs, organ system, organismal
Why would a normal temperature be a requirement for life?
Temperature affects every chemical reaction within the body. Those reactions break down and process everything we take in.

Stimulus, Receptor, Control Center, Effector
Why are hydrogen bonds not considered chemical bonds?
They do not share electrons. They are between molecules not INDIVIDUAL atoms.
What was the score for the ETSU v UVA Wise football game this Saturday?
