Don't Stump the Layman: Science Addition

You missed #14! (Dopamine).

A13) Not quite. A stroke is an interruption of blood flow to the brain (due to a number of factors) whereas an aneurysm is a ballooning of the vessel causing pressure on brain tissue.
A14) ANSWER IT.
A15) False is correct and your reasoning is sound. +1!
A16) It is a rapid rise and fall in the electrical potential of a neuron that cannot be explained by the passive electrical properties of cell membranes.
A17) Acetylcholine.
A18) You got one of them. They are totipotent (can become any cell) and can self-renew.
A19) False. Adult neurogenesis happens in the subgranular zone of the hippocampus, the subventricular zone, and possibly in the cortex as well.
A20) Memory is correct. +1!
A21) Alpha-helices and beta pleated sheets.
A22) Cuts DNA at specific sequences.
A23) Retroviruses are integrated into the DNA of cells. +1!
A24) Information in biological systems flows in the order: DNA->RNA->protein.
A25) Prions are misfolded proteins that can alter the folding of properly folded proteins. They are heritable and transmissible and actually violate the Central Dogma as it is typically stated.

I think I am in last place.

I got you to the bottom, posthaste!

Ahh well, I learned a lot!

  1. As for Dopamine, I’ve heard it thrown about when talking about neurotransmitters in the brain and the sensation of feeling good / joy / euphoria?
  1. Correct. It stimulates milk production.
  2. C6H12O6
  3. Nope. It’s the theory that Mitochondia were originally protobacteria that were consumed by other larger cells, and this is what led to the evolution of Eukaryotic Cells, because our Mitrochondria in our bodies have separate DNA than we do, and it’s circular DNA, which is normally found in bacteria. So mitochondria may have been living proto-bacteria that were taken up by cells, and created a symbiotic relationship allowing more complex cells due to a more efficient means of obtaining Energy.
  4. It DOES reduce inflammation by an allergic reaction. However, it opens the Respiratory system and CONSTRICTS the vascular system… So you’re 50-50.
    Your Call?
  5. Dehydration is correct.

Wow, I can’t believe I got Cholera right. For every victory, I make two mistakes. To all those who thinks this game is easy, let RoOsh and nameless share their stories. The gaps in my knowledge know no bounds!

Although, I think nameless dug himself (herself?) into a hole with a shovel called Esoteric. :smiley:

The latest tallys. Still waiting on Cardinal’s answers. And will Maui Lion, sturmhauke, pravnik, Lord Il, Inner Stickler, Darth Sensitive, LOUNE (c’mon buddy) and appleciders rejoin the fray? Do they have the guts to continue to probe my ignorance?!

p.s. RoOsh, In clear conscience, I had to mark the Epinephrine one wrong. I knew its function, but didn’t understand the mechanics entirely, as was asked for. Ahh well.

  1. What’s an alpha particle?
  1. A decayed neutron?

No, it’s a helium nucleus; 2 protons and 2 neutrons.
2. What’s the mass of one mole of Carbon-12?

  1. ugh, I don’t know moles.

12g. I know, that’s almost a head-smacker.
3. What’s neutral pH?

  1. I remember the half-way point between alkaline and acid is at 7 on the scale. Acids are higher than that, and bases are lower.

Good!
4. What’s absolute zero in Celsius?

  1. Well, it’s 0º Kelvin. :smiley: I do remember that it’s like -460ºF… But I can’t remember it in Celsius! sigh I’ll take a stab. Here’s my logic:

Freezing point = 0ºC / 32ºF — Boiling Point = 100ºC / 212ºF… ergo… that’s a spread of 100 degrees for C, and 180º for F.

That’s a 1:1.8 ratio.

So, -460 ÷ 1.8 = -255.6ºC?

If I get that right, I’ll eat my hat.
That’s actually a very good college try at the problem. Absolute zero is -459.67 F (I had to use Google). In fact, I’m at a loss right now as to how you’re as far off as you are. AZ in Celsius is -273.

Ah! I think the problem is that standard high school algebra assumes that 0 is in the same place for all numbering systems, or more to the point, that you’re using the set of integers, etc, and that 0 is something they have in common. In this case, it’s not.

Yes! The back of the envelope confirms it. F freezing is 491.67 degrees from AZ, which divided by 1.8 yields -273.15C, which is even more accurate that what I had said above.
5. All elements heavier than lead are ___________.

  1. Transition Metals?

Radioactive. (Not only are they not all under the trough in the periodic table, at least 2 aren’t metals. But I admit I looked at a periodic table for that second part.)
6. What is the heaviest naturally occurring element?

  1. Uranium?

Good!
7. Name 3 indications that a chemical reaction has happened.

  1. Change in temperature; change in volume; change in color? (I’ll bet that’s not what you were looking for :sobs: )

Well, we have to decide what to do with “change in volume” and “change in temperature”. I can heat a bridge girder and expand it until the rivets fall out, but that doesn’t mean it’s not still bridge steel just like before. I’ve also supplied the heat from an outside source. If you really meant that you mix something and heat came out on its own, then you can have that one. If I just pop a balloon, the gas inside will expand in volume. That’s just a spreading out, not a chemical reaction.

So can I no longer ask Questions? I think in another 25 I could get back into the positives. I’ve learned to try to limit my Biology questions to only 2-3 of the 5 Qs i ask at a time.

(and I love this sorta game btw, the “i’ll take on all comers” sorta thing. Kudos for you to doing this).

By all means… still keep track of your score, but your first 25 Qs will remain locked in. If there are people who still want to roll, we can up the ceiling later, I guess. Looks like we might have to drop some that decide not to come back. (cowards!)

I’m gonna give a “no” to #1, only because I had no idea there were protons involved. But, I’ll give #7 a “correct” because you can argue that you can derive heat from a chemical reaction such as sodium + water. Also, adding certain compounds together might produce a gas, or change in density… therefore volume goes up. Yes?

Where did you get those numbers! I only see 7 questions from you. :smiley:

Also, DAMN! on AZ. I now see the errors in my calculations, thanks to you. But all I had to work with was my knowledge of the freezing/boiling points of water. Could I have figured it out algebraically some other way, with only those four bits of data?

And yeh, Radioactive was my second choice… but I didn’t think it started so high up. DAMN DAMN!

You know, there’s another way we can tally scores if you want to ask an indefinite amount of questions. We can calculate ratios of asked:score. Would that work, or even be fair?

I meant that one of them, #7, was possibly 2/3 right. Question 1 was just wrong.

As for #7, producing a gas is not the same as increasing in volume; see my girder example.

I thought we were totaling your score against the board, not against individuals. I took the score from the previous poster.

I don’t think you can use only the boiling points and freezing points to find AZ. You have to have some idea how far down AZ is on some scale. Otherwise it might be -1500F for all you know.

As for #7, I guess you have to decide if you’re playing by party rules, or science nerd rules. I’ve found that if I let pretty much anything slide in class, some kid will get the wrong assumption and then throw it back in my face that it’s what I taught, so it’s my fault. So I say, “I’m going to get science teacher nerdy on you here, ok? It’s not so much _________ as _________.”

  1. What is Cherenkov radiation?
  2. What is Hawking radiation?
  3. What is a Bose-Einstein condensate?
  4. Astronomers recorded an odd event in 185 AD. What was it?
  5. What made the dwarf planet Eris difficult to discover?

Ah, that’s okay. The answers were:

  1. Polaris - Correct
  2. Thuban
  3. Vega

I’ll try some easier ones:

  1. What is the brightest star in the night sky?
  2. Name two stars in the constellation Orion.
  3. Name a moon of Mars (hint: think of the “Doom” video game).

  1. I very vaguely only know the term. Don’t know.

  2. Isn’t that the decay/emissions of a black hole?

  3. Okay, this is a mind scraper, but I think I remember the very basics. When Atoms are cooled very low, they start to exhibit quantum effects as a whole? Or on a macro scale?

  4. I believe it was a supernova within our own galactic back yard.

  5. Its on the other side of our orbit, for the most part?

  1. Sirius

  1. I believe Messier was an 18th century astronomer, and he cataloged several “fuzzy” objects in the sky, which were later uncovered to be nebulas and galaxies (such as M31, the Andromeda Galaxy).

  2. That’s a binary, I think. I’m going to guess “blink”?

1.) Name at least 4 of the 6 Quarks
2.) What compound will get you drunk?
3.) 2003 UB313 was found in distant orbit past Pluto, what was it’s ‘nerd name’?
4.) In physics and astronomy, redshift occurs when the electromagnetic radiation, usually visible light, that is emitted from or reflected off an object is shifted towards the (less energetic) red end of the electromagnetic spectrum. Who discovered this?
5.) There is intense international interest from scientist about the new Large Hadron Collider in Geneva because it could theoretically produce what natural phenomenon?
