SciShow Quiz Show with Phil Plait

Michael: Ladies and gentlemen, boys and girls,welcome to SciShow Quiz Show, the show where the points are made up, but the science isreal. I'm your host Michael Aranda. Today we have senior SciShow White House correspondentHank Green versus the Crash Course Astronomy host Phil Plait. Hank, you are playing onbehalf of Aimee Eisiminger. Hank: Hi Aimee, how's it going, I'm gonnawin! Michael: And Phil, you're playing on behalfof Ian McDowell. Phil: Hey Ian. I'm talking to you althoughyou're not actually here right now. Hank: Weird.

Michael: To find out how our contestants canplay for you, you can go to Subbable SciShow. Both of you start out with 1,000 points. Eachtime Phil: I quit. I'm done. That's it. Michael: Okay. See ya. Hank: Sometimes that is the best policy. Ihave ended below before. Michael: Ah, each time you answer a questioncorrectly, you will win some number of points that I make up at the time.

Hank: The Hawaiian one. Kilauea. Michael: You are incorrect. Hank: Aw, it turned red.

Hank: I just always see those YouTube tutorialsof lava pouring out of Hawai'i, and I'm like, Well that makes sense.

Phil: I have 3 answers. I have to pick fromone. Um, it's either Edna or Stromboli. I'm going to go with Edna. Michael: Incorrect. Hank Phil: Ugh! Green Screen Michael: The correct answer isStromboli. An island volcano off Italy's western coast, Stromboli site on the northern boundaryof the African Plate. And according to the US geological survey, it has been in a nearconstant state of eruption for at least 2,000 years. Stromboli is known for its unique styleof eruption, which involves almost hourly

Old Odd Archaea Bacteria Protists CrashCourse Biology 35

We've spent the past fewmonths talking about animals here on Crash Course, specificallyhuman animals, because. well, because humans.we love talking about ourselves, and also because animalsare just really interesting. But it's high time that we talkedabout the rest of the living world. Because I hate to break it to ya,but most of the alive things on Earth are singlecelled organisms. And by quot;most of the alive thingsquot;I mean that these organisms

make up two of the threetaxonomic domains of all life, plus one of the four kingdoms. I'm talking about archaea,bacteria and protists. With the exception of a fewprotists, they're all unicellular, and they are, by far,the most abundant and diverse organisms on Earth. More important, they layclaim to the world's oldest and earliest living lineages,dating back to the very first

twinkle of life on this planet. So by understandingthese three groups, you begin to truly understandlife on earth, its origins, and how everything that came afterthem, including us, came to be. What's more, becausetheir heritage is so ancient, these organisms oftentake weird, cool forms that don't look like lifeas we think about it, and they do amazing things.

Some not only live but thrivein environments that would kill you, me, and everything we hold dear. And others make theirliving by invading organisms, including us, and causing disease. Then there are those that do theopposite, making life possible by, fixing nitrogen from the atmosphereand helping animals digest food. Members of these groups havenames like Sailor's Eyeballs and Dog Vomit Slime Mold,and they can take the shape

of rods, blobs, corkscrews or coils. Kinda like the doddering,eccentric relatives you're forced to spend some holidaywith once a year, the archaea, bacteria and protists areour oldest, oddest relatives. And it's about timeyou got to know them. There's no denying it:Every multicellular organism on this planet, whether it bea mushroom or a vampire bat,

evolved from asingle celled organism. And while some of these singlecelled organisms evolved to populate the world as rhinos and stranglerfigs, others found happiness in the unicellular lifestyle, and they haven't changed muchin the past few billion years. Today, nearly all unicellularorganisms are either archaea, bacteria or protists. Protists, you'll recall,are eukaryotic organisms
