Questions and Answers
How does the ectothermic nature of most reptiles influence their behavior in environments with varying temperatures?
How does the ectothermic nature of most reptiles influence their behavior in environments with varying temperatures?
- They are unaffected by external temperatures due to their waterproof scales.
- They maintain a constant internal body temperature regardless of the external temperature.
- They must behaviorally regulate their body temperature by seeking or avoiding heat sources. (correct)
- They generate their own body heat through metabolic processes.
What primary advantage do shelled eggs provide to reptiles in terms of reproduction and habitat?
What primary advantage do shelled eggs provide to reptiles in terms of reproduction and habitat?
- They allow reptiles to reproduce exclusively in aquatic environments.
- They increase the mobility of reptiles during the reproductive season.
- They eliminate the need for parental care after the eggs are laid.
- They protect the developing embryo from dehydration on land. (correct)
If a certain animal is observed basking in the sun to raise its body temperature, which of the following regulatory mechanisms is the animal expressing?

Flashcards
Reptile Egg Laying
Reptile Egg Laying
Reptiles deposit amniotic eggs enclosed in shells on land.
Reptile Scales
Reptile Scales
Reptiles have scales, composed of keratin, creating a waterproof barrier that prevents dehydration in terrestrial environments.

Study Notes
- Reptiles lay shelled eggs on land.
- Scales create a waterproof barrier for reptiles.
- Most reptiles are ectothermic, absorbing external heat to regulate body temperature.
- Birds are endothermic, using metabolism to maintain body warmth.
