Homeostasis and thermoregulation
When temperatures are too low, these processes may be disrupted, which can lead to cellular damage and even death. Homoeothermic endotherms, such as bears, bats, and birds, regulate their body temperature by generating heat internally.

Answer: Denaturing
Explanation: Enzymes are made of amino acids that are linked by bonds, amongst those bonds are hydrogen bonds that are very weak. High temperatures and low pH(acidity) breaks those bonds changing the molecular conformation of the enzymes. That way they denature and loss the ability to perform their functions. High temperatures and acidity alter the structure of their active site preventing the substrate from binding to them. While high temperatures denatures enzymes, low temperature renders them inactive.
Yes, it’s main function is to protect the organisms from germs, bacteria etc... and cover the essential organs from these organisms too.
It’s true. Stems are organs that hold the trees and plants up and also produces the leaves and secondary stems
