Definitions

Question 1

Homeotherm

Answer 1

maintains body temperature at a constant level by metabolic activity (body temperature usually higher than environment)

Question 2

Heterotherm

Answer 2

Variable body temperature (exhibits both homeothermy and poikilothermy)

Question 3

Poikiliotherm

Answer 3

an organism that cannot regulate its body temperature except by behavioural means such as basking or burrowing.

Question 4

Ectotherm

Answer 4

Organism dependant on external sources of heat

Question 5

Endotherm

Answer 5

Organism capable of internal generation of heat

Question 6

Stenotherm

Answer 6

able to tolerate small changes in temperature

Question 7

Eurytherm

Answer 7

able to tolerate large changes in temperature

Question 8

Conduction

Answer 8

Direct transfer of heat (skin on skin)

Question 9

Radiation

Answer 9

Indirect transfer of heat - sun to skin

Question 10

Convection

Answer 10

Transfer of heat by gas (fire - skin)

Question 11

Evaporation

Answer 11

Phase transition - cooling effect - water to gas is a endothermic reaction

Question 12

UCP?

Answer 12

UnCoupling Protein

Question 13

BAT

Answer 13

Brown Adipose Tissue

Question 14

Q10

Answer 14

A measure of temperature sensitivity of an enzymatic reaction rate or a physiological process due to an increase by 10 degrees.
