Hello, so let's answer now the question.
00:03
So we are looking here for the term that refers to the maintenance, okay, maintenance of internal conditions in an organism.
00:26
Okay, of an organism.
00:31
Okay, so here we have the word evolution for letter a.
00:35
Evolution is changed through time and that is not the answer because, again, we are referring to the maintenance of the internal condition.
00:43
Like for example in humans the internal conditions of the sugar level in our blood it needs to be balanced the condition uh in uh for example the amount of um ions in our body needed uh to be balanced so that is what we call or that is the term the term that we are looking for it's not evolution and for letter b we have metabolism metabolism is the the the the the the the the the sum total of all chemical reactions that happen in our body and that is not also the answer we are not referring here to metabolism and here we have letter c we have adaptation although adaptation can lead to maintenance of internal conditions but it is not the proper term so this is not our answer so let's go to e first okay e option e is photosynthesis it's the conversion of light energy water in carbon dioxide into glucose and this is not our answer our answer here is we have option d or what we call homestasis so homestasis is the internal balance in an ecosystem so homeostasis is the internal balance in an ecosystem so so the word homestasis came from two greek words, okay? two greek words, which means same and steady.

So basically, when we speak of homestasis, it refers to any process that living things used to actively maintain fairly stable conditions, which are necessary for survival...
