    I can’t believe That we finally finished invertebrata 😃
    Like why do they put biological names
    What does it called bionomenclature ?also can u do “ecology , consumers , herbivores , carnivores , omnivores and interaction” video cause literally I didn’t understand anything about them.

      Hi! So binomial nomenclature 'translates' to "two-word name" referring to the scientific name of a species (Homo sapiens for example). The two 'words' used are the genus and species of a particular organism. For your other things, I do have some videos that may help:

      And this UA-cam playlist: ua-cam.com/play/PL2bH1t806pNL5f65sJugE5hNGR0ILPyl5.html

    Hey Professor Newtoff! I am looking at some more of your videos just for fun, and I was wondering if you could explain cervical, thoracic, etc. Looks like different types of discs, but I was wondering about the different types and what they are for. Thank you!

      We might have watched this video in class, but there were so many that I cannot remember for sure.

    Yes hello, first of all, I admire you, second, since reptiles came directly from amphibians, shouldn't there be a common characteristic which makes a distinct category? Or better yet, as direct descendants of lobe finned fish , shouldn't all these species be classified under a certain category? Wouldn't this be more efficient for taxonomy and understanding evolution? Or do some evolutionary paths not create distinct enough difference to be in a class of their own?

      Thank you! But you have it backwards -- amphibians came first and then reptiles. Amphibians have the root "amphi" meaning both, referring to their lives in water (like fish) and transitioning to land (like reptiles). Most amphibians lay eggs and initially develop in water and spend their adult life on land, though usually near water. Their eggs need to be in an aqueous environment. In reptiles, we see the evolution of the amniotic egg. This egg has a hard shell (think like a chicken egg), and no longer needs to be in water. Reptiles also have scales which helps to prevent water loss through their skin, increasing their independence from water.

    Hey prof! I am in great confusion can you help me? Which university is the best to study botany and zoology in America that would accept international transfer students?
