The lower two fish are remora. The top has a similar body shape, but a pec and no sucker. It is right side up as are the other two fish. Please be able to back up your answers.

thanks!

Let B be a Baire space without isolated points that satisfies the T1 axiom. Suppose B contains a countable and dense subset D with complement D'. Can there exist a continuous f:B --> B that sends elements of D into elements of D' and vice versa? Specialize your conclusion for the case of R, Q and I. In this case I know such function doesn't exist, but the proof I know is based on cardinality, not Baire spaces.

Thank you for any help.

I am having a HUGE spider problem at my house. These suckers are EVERYWHERE. It is freaking me out because they look a bit like Brown Recluse spiders, but the ones I've gotten close to don't look like they've got the "fiddle" on their backs. They're fairly large, have long, narrowish bodies (abdomens?), and are extremely fast. I have never seen any spider move that fast. So what I want to know is, are there any spiders similar to the Brown Recluse, and what are they? Are they poisonous? I've seen what happens to Brown Recluse bites, and I don't want none of that. Any info would be great.

I normally would try to find the answer on my own before coming here, but I loathe spiders... I can't even stand to look at pictures of them, and I know any site I go to will have pics.

Thanks!

I know I need to fast for 12 hours prior to the test. However, will a meal roughly 15 hours prior to the test affect it? (i.e. prime-rib, or shrimp.) These things are high in cholesterol.
