+ykOni Yeah! I personally would've chosen to be taught at KZfaq rather than my high school, imagining a world where we no longer have to even move from our homes to get the best quality, entertaining, active learning. Even standardized tests like the SAT can now be prepped for online by some of the most highly experienced mentors-people you wouldn't normally find at your local high school! Whether this happens to be true or not, we have to thank people like Hank and John for giving us such beautiful, free stuff!!!!! And finally, DFTBA!

Notes: Animal cell Eukaryotic cells, with membrane ,organelles and nucleus containing DNA that calls the shots Animal, plants, fungi and protist Flexible and squishy membranes as oppose to plants, allowing the creation of cell, organs and tissue types Cell is like a city: On the surface: Microtubials: made of long protein fibers: Cillia (tiny arms like in lungs and throat pushing the mucus up) and Flagella (whip-like tail like in sperms), Protozoans, move with Microtubials instead of muscle tissue Membrane: Selective permeability: monitoring coming in and out like boarders Inside: Cytoplasm: water+nutrients Cytoskeleton: scaffolding made of protein strands, Centrosomes: infrastructures Endoplasmic Reticulum (ER): network of membranes like a highway system The smoother parts of ER are like factories: containing enzymes (proteins) producing lipids, detoxifying substances by adding carboxyl to make them soluble in water, storing ions like Sodium used for energy The rougher parts of ER have Ribosomes attached to them: Synthesis and packaging of proteins Ribosomes: float freely, assemble amino acids into Polypeptides pushing the protein chain into ER where it's bitten off and sent to Golgi Aparatus Golgi: made of membranous layers: the post office for packaging proteins, cutting them into hormones, combining them with Carbs to make molecules Vessicles: the packages with Phospholipid walls Lysosome: waste treatment and recycling, sacks containing enzymes breaking down cell waste into building material Mitochondria: the power plant where respiration takes place, fuels converted to Adenosine Triphosphate (ATP) which is the currency They were separate bacteria that animal cells absorbed and kept, and they still act as their own organisms with their own DNA, they exist in the egg and doesn't mix with sperms DNA during fertilization Nucleus: The leader Contains DNA and has all the information and instructions Has a double membrane Nucleoplasm (is like Cytoplasm) Nucleolus at the center: creates Ribosomal RNA+proteins=Ribosomes Messenger RNA: carry the orders to Ribosomes Chromatin: web-like substance that holds DNA molecules, upon cell division they gather into rod-shaped chromosome, humans have 46

@liwendiamond9223 9 жыл бұрын

It's not only a case of our awesome host just being awesome at teaching. It's a lot easier to teach in front of the camera with the power of post-production on your side than in a live environment. The pacing is just right and the visual supports are incomparable. Plus in the comfort of your awesome office chair sitting isolated in your room, you are actually much more likely to be focus and attentive than in the middle of a class room full of noises, whisper, hot girls, hot boys and sitting in a crappy ass chair. You can also pause and rewind stuff you didn't quite understand without having to stop a teacher in the middle of his speech and pissing off every other person in the room. You don't have to suffer awkward relations with other people like bullies and that one girl who mercilessly rejects your advances. You don't even have to leave your home, the one place in the world that feels the most familiar and secure or all places. Public schools are one of the worst environments possible to actually learn stuff. Back when we didn't had endless access to the entire knowledge of the human race in one single device; a computer with a functioning internet connection; schools were the best tool we could get to ensure everyone would have a chance to learn. They feel terribly outdated when compared to a channel like crash course. But I can't deny the quality of these videos. I mean I've gone trough 6 years of college/university all about biology. I know all of this stuff he's trying to teach and yet I'm watching it for fun! And perhaps a nice refresher on the basics. It's such a nice way to keep the brain warm. Would I go as far as to say it's good enough to fully substitute actual school? For some people, yes. Crash Course would be enough to substitute most of high school (Except maybe for maths. I didn't see a maths playlist. I think even KZfaq can't make maths exciting enough...) The problem with MOST people is they wouldn't want to learn this stuff if they weren't obligated to at least give it a try by attending school. If given the choice, they would rather spent their teen years playing videos games or sports, or both and hanging out with friends and losing their virginity and making a bunch of dumb mistakes, some of which would get a few killed, like starting one's home business in drug dealing at the innocent age of 12. Most humans can't be trusted with choice...

You should create quiz after every video with questions on the topics discussed in each video, or during the video a pop quiz.

this is just a "crash course" I used these videos to better understand the major themes and then went over my lectures notes and it helped out so so much! Got an A in Bio 1, hoping to do the same this year in 2 and in A&P with the help of crash course. Thanks guys!!!!

+Samuel Bernstein I haven't taken ap bio yet so I don't what they teach there, but in my 9th grade bio class I didn't learn half of this in 10 times the time. I enjoy learning science and don't enjoy slow classes so I prefer this.
