Hello everyone and welcome to today's video. So blank refers to the protection of the internal environment against the harms of changes in the external environment. Let's go over each of our answer choices so that we may solve the problem. Beginning by answer choice A We have thermal regulation and more regulation refers to the maintenance of the internal temperature of the organism. This is not going to be in terms of the external temperature or the external environment. So we're going to cancel this out. Then we have defecation and defecation as we know is a removal of digestive waste. Is this is not going to be the protection of the internal environment against changes of the external environment. So we're going to cancel this out as well. Then we have evaporation and evaporation refers to the loss of water as water fever. Again, this is not really the protection of the internal environment against the harms of changes in the external environment. So we're going to cancel it out and we're all left with home use stasis. Remember from previous videos that home use stasis refers to a stable state. It is a group of reactions in our body that helps us keep a stable state or a constant state of the internal environment. In terms of the external environment in order to protect the organ against sudden changes of these external environment that inherited because of this whole meal stasis is going to be the correct answer to our question. I really hope this video helped you and I hope to see you in the next one
