    Birds(Aves) are Reptilia. they are a type of Theropod. We make terrible use of the word reptile. Probably more Reptiles and endothermic than exothermic, it just so happens that most reptiles died in the KT extinction event and we are left with crocodilians, snakes, turtles and lizards with Aves being the only extant member of the large family of dinosauria (crocodilians, snakes, turtles and lizards are not and never were dinosaurs) Crocodilians have a 4 chambered heart like endotherms and some other endothermic parts, but possible evolved to shed that and developed a shut as well as other biological changes, since endothermy is not conducive to the lifestyle they adapted to when taking to the water. It requires too high of a metabolism to sustain in the niche they filled. Birds and Crocodilians are Archosaurs. Turtles, Snakes and Lizards are not.

    My genetics teacher is absolutely so ineffective with teaching- for me. I have ADHD and it's so hard to concentrate in class let alone read a textbook, but your videos are helping me study for my exam, because there is so much information regarding differences in eukaryotes and prokaryotes and a huge emphasis on the lac operon system and mutations that can occur. Thank you for explaining this so well

    While fermenting a grain and sugar mash to make alcohol I had the idea to run my grain mash through an ultrasound to decrease particle size to make the grain mash more bioavailable to the yeast. The results were incredible. I am wondering if you can also try this on a grain mash and measure the results between the ultrasound mash and a control. I did a very short clip showing my bubbler and fermentation bucket. ruclips.net/video/xlaGz_3mKhU/видео.html After this I tried a sugar wash through the ultrasound unit but it did not seem to increase the rate at all. Probably because the dissolved sugar was already at it's smallest size. It did seem to point to the fact that the yeast did better with the smaller particle grain mash than it did with the sugar wash. I really would like to see someone do more testing and research on this as it could have a huge impact in several fields like fuel and space travel. That and I like the idea of giving back to the yeast something it likes for its centuries of service to humankind. #Yeast lives matter. I would love a reply with your thoughts. Been working on soil and foliar fertilizers and making them more bioavailable to the plant microbiology and cell wall penetration. #Nano Nano

But I am very interested in your different scenarios. Would you be willing to share what these are or if you have a write-up to go along with this? I am a JR high science teacher in Ohio.
