Question 1A person enters a heat chamber carrying a raw egg on a plate. As the temperature is gradually increased, the exposed egg is cooked while the subject continues to have a normal internal temperature by mouth thermometer. What mechanism is lacking in the egg but is present in the human subject that maintains homeostasis?
Lack of a circulatory system prevents the egg from distributing the heat.
The egg cannot “breathe away” hot air to “air condition” its body.
The surface-area-to-volume ratio prevents the smaller body from losing heat as fast.
Increased sweating causes evaporation that carries away heat.
The human subject contains more fluid volume to absorb heat.
Question 2Bone
is made of only a hard matrix of inorganic (mainly calcium) salts.
is lacking blood vessels and canaliculi that deliver nutrients.
is formed by concentric rings of bone cells in canaliculi.
is built by bone cells called osteons.
lacks the collagen fibers found in cartilage.

salty sweat; sweat glands
pili; erectors
