Nitrogen
Which of these describes the process of autolysis?
The self digestion of a cell
Chemistry is the study of
all of these
What substance is produced by the dehydration of an organic acid and an alcohol?
an ester

isotonic
Two solutions having equal osmotic pressure are said to be:
isotonic

Glutaraldehyde
The measure of a liquid's resistance to flow is
viscosity
The important vehicle for an arterial solution is
water

myosin
The characteristics of a substance observed without altering the composition of it are
physical properties
The most complex of all carbohydrates are the
polysaccharides.
In the compound water, hardness is caused by
presence of metallic salts.
Embalming prevents the decomposition of
proteins
Peptide linkages may be found in the formation of:
proteins
The anaerobic decomposition of proteins is called:
putrefaction
A non-metallic element becomes electrically charged by
receiving an electron.
Electrolytes are substances which, in solution,
release both positive and negative ions.
The primary function of acetone in embalming fluids is:
solvent
The density of an object divided by the density of water is
specific gravity.
The passage of a solid substance directly into the gaseous state is
sublimation.
