Endothermic animals maintain their body temperature using:

• External heat sources

• Stored glycogen

• Fur, fat, and feathers for insulation

• Ectothermic mechanisms

How is basal metabolic rate (BMR) defined?

• The amount of energy an ectothermic animal uses at rest

• The energy expenditure of an endothermic animal at rest

• The energy an animal uses during movement

• The energy stored in fat cells

Smaller animals typically have a higher BMR per body weight compared to larger animals because:

• They have a greater surface area to volume ratio

• They lose heat more slowly

• They need less energy to maintain body temperature

• They store more fat

Which type of epithelial tissue is most commonly found lining the digestive tract?

• Squamous epithelium

• Simple columnar epithelium

• Stratified cuboidal epithelium

• Pseudostratified columnar epithelium
