每日一題 (bio MCQ) 1/5 WITH ANSWER



Which of the following concerning the above animal is correct?

A. Its skin facilitates its locomotion
B. It is physiologically adapted to humid and warm environment
C. Its skin is moist so as to keep it hydrated
D. It is an omnivore


The correct answer is A (54.8%)

B

C

  3 (9.68%)
D

  7 (23.33%)


Many candidates wrongly chose D because they have ignored the fact that "sand cobra" (the animal in the picture) lives in deserts (ilustrated in the picture). Such a hot and dry environment leaves no room for plants to grow. Therefore, sand cobra is a "strict carnivorous", they only eat small animals for food
Snakes are reptiles so they are characterized by having dry scales. Dry scales on their skin increase the friction between their body and the sandy surface, helping them to move more easily
