Which of the following is an example of homeostasis?
a. a human body loses too much heat on a cold day, adn hypothermia occurs.
b. a cactus stores water during wet periods, allowing it to live through dry periods
c. a snake rests in the sun on a summer day, and its body temperature becomes too hot for survival.

B, A cactus stores water during wet periods, allowing it to live through dry periods.

Explanation:

Hiya! So, the reason it's B is because homeostasis is an cell/organism's ability to maintain constant bodily equilibrium, allowing it to survive during the cold and heat.

For example, we humans are able to maintain a healthy body temperature of 98.6°F/30°C, which can automatically adjust to better fit the climate we're in.

Hope this was helpful ^^

the most logical answer would be a
