check my answer
question 2
if you see a snake coiled up in a sunny patch of grass, what can you probably conclude about the type of thermoregulator it is. why?
check my answer

Explanation:

Question 1:

• Elephants: They use large ears for thermoregulation. The large surface - area of their ears allows for heat dissipation as blood vessels in the ears can dilate, releasing heat into the environment.
• Arctic foxes: Have thick fur coats to insulate their bodies. The dense fur traps a layer of air close to the skin, which acts as an insulator, reducing heat loss in cold arctic environments.
• Honeybees: In cold weather, they huddle together in a cluster. By clustering, they reduce the surface - area to volume ratio exposed to the cold, and also generate heat through muscle contractions. In hot weather, some bees will fan their wings at the entrance of the hive to circulate air and cool the hive.

Question 2: Snakes are ectotherms. When a snake is coiled up in a sunny patch of grass, it is likely trying to increase its body temperature. Ectotherms rely on external sources of heat to regulate their body temperature. Since they do not generate much internal heat, they use behaviors like basking in the sun to warm up their bodies, which helps with metabolic processes such as digestion and movement.

Answer:

Question 1: Elephants use large ears for heat dissipation, Arctic foxes have thick fur for insulation, and honeybees huddle in cold and fan wings in hot conditions.
Question 2: The snake is an ectotherm. It is basking in the sun to increase its body temperature as it relies on external heat sources for thermoregulation.
