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

The significance of hard water to the embalmer is that the salts that cause hardness in water also

cause blood clotting.

Substances which release both positively and negatively charged ions when in solution are classified as

electrolytes

In arterial fluids, glycols act as

humectants

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.
