Hi everyone! It's been nearly a month since my last post, but I've been traveling since getting off the Ice. So much to talk about and TONS of pictures for all of you.
But first thing is first: the winner of the pub trivia challenge! I'd like to start out by saying that when I posted the biology trivia questions I was expecting I'd get responses from very few people. In fact, I expected responses from just three or four people. Turns out I was bang on. Three people participated, and they were exactly who I thought they would be. Those three people, (you know who you are), thanks for playing! You all did really well! The scores: RRR with 30 points, RR with 34, and KW with 41. The scores were really close and there were only three of you so you'll all be getting something! I'll be in contact to talk about your prizes. :) For those interested, here are the answers:
1. a) 1 point for having ”1” bone. b) 1 more point for the name ”hyoid bone.”
2. a) 1 point for ”nephron”. b) 1 point for ”juxtamedullary nephron”.
3. 64 days. (1 point for any answer between 54 and 74).
4. Endoderm, Mesoderm, Ectoderm
5. a) Cervical vertebrae, Thoracic, Lumbar. b)cervical (7), Thoracic (12), Lumbar (5).
6. a) Myelin sheath (layer) I’ll also accept Schwann cells (PNS) or oligodendrocytes (CNS). b)
Primary role is to speed up conduction of impulses down an axon by reducing surface area of uninsulated axon to periodic nodes. Instead of propagating continuously down the axon, nerve impulses hop across the insulated axon to uninsulated nodes, dramatically increasing the speed of propagation.
7. Cytoskeleton, ER or Endoplasmic Reticulum (if separated into smooth and rough ER, I’ll accept it as 2 points), flagellum (plural flagella), Golgi Apparatus, Mitochondria, Vacuole, Nucleus, Acrosome, Autophagosome, Centriole, Cilium (pluaral cilia), Lysosome, Melanosome, Nucleolus, Myofibril, Peroxisome, Ribosome, Vesicle. 19 possible points! (I admit I missed a few myself... :( )
8. a) Among other differences, rods allow us to see in black and white, while cones gives us color vision. b) Cones are most highly concentrated on the back of the retina, near the optic nerve, specifically in a patch called the "Fovea Centralis" or just "Fovea."
9. The diaphragm.
10. cerebellum
11. Hypothalamus
12. a) 23. b) 21. c) Chimpanzee (48, while a human has 46 total chromosomes).
13. a) Cellular mitosis and meiosis. b) Mitosis leaves both daughter cells with complete copies of each chromosome. Meiosis gives each daughter cell (4) a copy of only one chromosome in a pair.
14. Starches (carbohydrates) and fats (lipids) (1 point for each).
15. ATP (adenosine triphosphate)
16. a) amino acid. b) 3. There are 4 base pairs. There are 20 standard amino acids the body produces, so you need at least 20 distinct combinations. 4^2 = 16, so you need at least 3 base pairs to have enough combinations (64) c) Lysine. d) AAA or AAG (adenine, guanine) (no cytosine or thymine[uracil]).
17. Pinna (or auricle)
18. Dura Mater
19. Corpus Callosum
20. sphygmomanometer
21. Phospholipids.
22. Cochlea.
23. Semicircular Canals.
Thanks again to Mrs. Iler for being such an amazing biology teacher in high school!
So, what have I been doing the past few weeks? Well, two nights before leaving the Pole we all decided it'd be a shame to be in Antarctica without watching John Carpenter's The Thing, so Thursday Feb 2 that's exactly what we watched. Nothing like a good horror/thriller to make you feel uncomfortable about where you sleep. The following night, my last night at Pole, we watched the new prequel of The Thing. It's all about the Norwegian camp that finds the Thing, and the end of the movie ties into the beginning of Carpenter's version quite nicely. The camera was working (albeit it still needs some optimization), the receiver team's job was essentially done, so it was a nice way to say goodbye to the South Pole.
Earlier that day I went out to DSL and the telescope one more time to help with a bit of clean up and to say goodbye to SPT. I decided to take a video of the telescope moving so here it is. The video is of SPT moving from inside the control room, directly under the dish. The telescope is almost entirely silent from outside - all you can usually hear are the pulse tube coolers pulsing helium gas back and forth (the higher pitched chirping in the video). I have other videos, from outside so you can see the dish moving, but they're too big to upload to blogger. If you're interested I can post they somewhere else.
In the receiver lab one last time... :(
