Question 15

The organelles with organelles with membranes of similar origin that are part of the Endomembrane System include: Golgi apparatus, lysosomes, endoplasmic reticulum, plasma membrane, mitochondria and nucleus.

Answer 15

F

Question 16

The more double bonds (unsaturated) on the fatty acids in the plasma membrane’s phospholipid bilayer, more fluid the membrane will be.

Answer 16

T

Answer 18

F

Question 19

Cotransport and countertransport can be used in secondary active transport.

Answer 19

T

Question 20

To determine the basal metabolic rate of an animal, we should consider standardized conditions – rest, fasting and thermoneutral zone.

Answer 20

T

Question 21

When animals are travelling at their most efficient speeds, flying is the most efficient.

Answer 21

F

Question 22

Thermal equilibrium occurs when both objects are at the same temperature and there is net movement of heat.

Answer 22

F

Question 23

While conduction, convection and thermal radiation are methods of heat transfer that can result in loss or gain of heat, evaporation is only for loss of heat

Answer 23

Answer 25

F

Question 26

In temperatures above the thermoneutrality, a homeotherm can lose heat through evaporative means such as sweating, panting and gular fluttering.

Answer 26

T

Question 27

If the skin thermoreceptors trigger that it’s cold, the hypothalamus core thermoreceptors decrease the “set point” and activate mechanisms to generate heat
