What is the difference between eccrine and apocrine sweat glands? -
ANSWER>>Eccrine sweat glands are most numerous and respond throughout to body
temperature elevated by environmental heat or physical exertion.
What is the difference between anatomy and physiology? - ANSWER>>Anatomy is the
study of the structure of body parts, whereas physiology is the study of the function of
body parts
What are the levels of organization? - ANSWER>>subatomic particles, atom, molecule,
macromolecule, organelle, cell, tissue, organ, organ system, organism
What are the requirements of life? - ANSWER>>Water, food, oxygen, heat, pressure
What are the characteristics of life? - ANSWER>>Movement (internal or gross);
Responsiveness (reaction to internal or external change); Growth (increase in size
without change in shape); Reproduction (new organisms or new cells); Respiration (use
of oxygen; removal of CO2); Digestion (breakdown of food); Absorption (movement of
substances through membranes and into fluids); Circulation (movement within body
fluids); Assimilation (changing nutrients into chemically different forms); Excretion
(removal of metabolic wastes)
Define homeostasis - ANSWER>>Body's maintenance of a stable environment
What is a homeostatic mechanism? - ANSWER>>the body maintains homeostasis
through a number of self-regulating control systems; examples are regulating body
temperature and pressure sensitive receptors to regulate body pressure
Define matter - ANSWER>>Anything that takes up space and has mass (weight). It is
composed of elements.
Define element - ANSWER>>fundamental substance composed of chemically identical
atoms
Define atoms - ANSWER>>smallest particle of an element; basic unit of matter
, What is the structure of an atom? - ANSWER>>An atom consists of a nucleus
containing protons and neutrons, with electrons in
orbit around the nucleus.
Atomic nucleus - ANSWER>>the nucleus contains protons and neutrons
Proton - ANSWER>>subatomic particle that has a positive charge
Neutron - ANSWER>>subatomic particle that has no charge
Electron - ANSWER>>subatomic particle that has a negative charge
Atomic number - ANSWER>>number or protons in nucleus
Atomic mass - ANSWER>>number of protons plus number of neutrons
What are covalent bonds? - ANSWER>>Covalent bonds are formed when atoms share
electrons to become stable with filled
outer shells
What are ionic bonds? - ANSWER>>2 oppositely charged atoms form this bond when
electrons are transferred from one atom to another atom
What are hydrogen bonds? - ANSWER>>Weak attraction between positive end of one
polar molecule and negative end of another polar molecule; formed between water
molecules
Define ion - ANSWER>>When atoms gain or lose electrons, they become ions.
Define synthesis reaction - ANSWER>>Two or more atoms or molecules are joined
together
Define decomposition reaction - ANSWER>>Larger molecules are broken down into
smaller ones
Define exchange reaction - ANSWER>>Parts of molecules trade places
Define reactant - ANSWER>>The starting materials of the reaction - the atoms, ions, or
molecules
