Welcome back. Let's look at the next question here. It says morpho species are differentiated from other species through, Well when we look at our answer choices, we've got a pretty big clue staring us in the face by the fact that Choice B. Here is morphology and our word is morpho species. And indeed that is the distinguishing uh characteristic that's used to to differentiate a morpho species. So the classification of amorphous species is dependent on morphology. The form or structure of a different species. This is sort of the oldest form of classifying species because it depends on what you can observe from the outside. So it doesn't include things like um ancestry relatedness, genome, things that we use today to classify things in the species. So let's look through our other answer choices. Just to be thorough here. Choice A says physiology physiology has to do with the functions of organisms or their parts so things like breathing heart rate. Um So rather than outside and you can think of like anatomy and physiology the class. Whereas morphology as part of anatomy, the form or structure physiology is how those parts function. So choice A. Is not our answer. Choice C. Says ancestry. Well as I mentioned, um ancestry is not included in morpho species. It's only based on those structures that you can be observed and choice D behavior behavior is not included in the division of morpho species. So our answer here is morphO species are differentiated from other species through Choice B morphology. See you in the next video
