I would say to avoid progressive senescence, which will eventually lead them to more vulnerability to disease, predators, etc and result in death anyway.

I live less than an hour away from the big Oak Ridge laboratory, a lot of people in my town work there. I was trying to get to a soccer game once and got very lost and somehow ended up near the laboratory, the security there is absolutely insane, which is actually a big comfort, it would be a prime target for terrorists...

it decreases bone mass if you have too much. something about dissolving calcium or helping it flow out of the body instead of being used... something like that' date=' i dont remember exactly.

That is not an exaggeration.

I'm 18 years old, extremely active, no family history of low bone density, blah blah blah, and I got diagnosed with osteoporosis yesterday, due to several years of not so healthy habits involving tons of caffiene and not a whole lot of food.

Just thought I'd make the point that YES, it will leach calcium from your system, I take my supplements religiously but it doesn't seem to have mattered. I even have a tooth that's starting to decalcify because my body was so desperate for it.

 

Anyway, there's an anecdote for you. Believe me, I'm a huge coffee lover (although I'm off caffiene now on doctor's orders) and am not trying to demonize it, just wanted to make the point that it can definitely be overused.

I have a laptop, and it tends to get hot after a few hours (I do have one of those ventilated lap desks for it, but apparently it's not that effective), and the fan gets on my nerves, so I set it to "hibernate" when I'm not using it and completley shut it down overnight. When I had a desktop I left it on all day and shut it down at night.

I hope everyone has a safe and happy holiday, best wishes to all.

I agree that it probably depends more on the type of music, younger generations are more into the type of music that sounds good with deep bass.

My dad has blown out two sets of speakers in his truck in the last three years...

This isn't nearly as serious as Coquina's, but I thought it might be noteworthy. When I had my wisdom teeth out they prescribed me hydrocodone for the pain, but I broke out in severe hives and kept passing out, so I stopped using it after two days and was fine...(the passing out could have been due to not eating, though, but there wasn't anything else I could identify to cause the hives, and they went away when I stopped taking it.) I know several people who've been on hydrocodone after surgeries, though, and none had that reaction.

I just reread your post and realized I didn't fully answer your question about frequency. The reason certain that things like polydactyly (extra fingers/toes) are rare and yet caused by a dominant gene is that not many people have the dominant allele, meaning the majority of the population is heterozygous recessive, so even a dominant gene can have a relatively rare phenotypic expression if not many people carry it. The type of dwarfism called achondroplasia (not sure if that's spelled right, sorry) is another example of a dominant allele that's pretty rare.

Dominance has to do with expression, not frequency. This means that if the organism is heterozygous, the dominant allele will be expressed in the phenotype and the recessive allele will not "show up." This is how people are carriers of diseases without actually being afflicted by the disease themselves. If B is brown hair and b is blonde hair, and brown is dominant, and a person's genotype is Bb, they will have brown hair but can have blonde children if they mate with someone who also carries the recessive (b) allele.

I think eating red meat alone is bad enough for you as you can easily get infections from uncooked meat.

I could be wrong, but I think the original question was referring to "red meat" as in beef, (in contrast to to "white meat" such as poultry), not "red meat" as in rare/undercooked.

Merry Christmas from Tennessee! It looks like we may have snow for Christmas this year, which doesn't happen very often, usually the only time people down here don't treat white stuff like a nuclear holocaust is when it happens to fall on a holiday.

Most of what I asked for was books an CDs, and a lot of Amazon.com packages have come recently, so apparently Santa's little helpers have been at work...and my biological dad always sends some money.

I had never heard that before, although I know Jewish law says not to eat dairy and meat together, so maybe there is some basis for it from "way back when." (Such as with their pork taboo, which originated because of common diseases from infected pork meat). Lots of times traditions that seem pointless now served a function at some point...anyway, if you find the answer I'm definitely interested to hear it.

I've noticed at my school that the foreign exchange students are almost invariably a lot more comfortable in math classes than subjects like history, literature, etc, the reasons being pretty obvious I guess, numbers are one thing they don't have to translate. There's a chinese girl in my AP Calculus class that speaks almost no English, but she always has one of the top grades in the class.

Does anyone know of a language/community that uses anything other{/I} than the common 1, 2, 3 numberical system? (I'm not being a smartass, genuine question, I couldn't think of one but I thought someone better educated might).

I live in a rural area and CAN'T get broadband (I'm NOT into porn but it irks me that downloading music is such a hassle). I also heard it on the headlines and wondered how the stats would change if dial-up users were polled for their activities...I guess it's just more patient porn-watchers in that category to wait for long downloads, lol..

I'm pretty sure you've got the right idea with your crosses, although I'm no expert, but it looks like you've got the concept.

Here is one confusing part. Is the WwRr' date=' a homozygous recessive? Because I know it's homozygous.. But I'm not sure whether it's call homozygous when there are four different kinds of possibilites.

 

And did I answer the question fully?

 

THANKS. [/quote']

Traits are independent of each other (well, in most basic problems, in reality they're often linked, but I'm fairly certain this problem isn't intended to be that complicated). That means that a WwRr is heterozygous for both traits, but if it were Wwrr it would be heterozygous for the wing traits and homozygous recessive for the eye traits, it can be different for each pair of alleles.

 

I hope that answers your question, and yes, it seems like you have a good grasp of the test cross concept.

Tell me why monkeys are not evolving nowadays, they had DNA change recently??

Things don't evolve in any "days", speciation is an extremely slow process under normal circumstances. Just because we haven't witnessed the emergence of branching primate species within recorded history does not mean that it does not happen. As for DNA changes, remember that humans themselves have a 99% similarity to chimps.

You need to know red-eyed phenotype results from a dominant allele, and what the possible phenotypes are. Generally if you want to determine heterozygosity, you breed the organism with the unknown genotype with one that you know is homozygous recessive for whatever condition you're working with.

Edit: It's been a year since my last biology class, so someone please correct me if I'm wrong.

My AP Calculus teacher informed us TODAY that there will be a test on Monday over the entire semester's worth of material. A month or two back she specifically told us there would be no semester exam. Math isn't my strong point in the first place, but a cumulative semester exam on three or four days notice...I'm going to implode over the weekend trying to study for this.

Sorry for the vent, I was a little angry and happened to come across discussion of math classes, it seemed like an opportunity not to be missed for letting off steam.

There was an article in a recent issue of Nature that talked about early Homo sapiens migrations and how it may have affected the disappearance of the Neanderthals, if you can get ahold of the pdf file it's definitely worth reading.

Actually the "one dog year is seven human years" formula isn't accurate. I work for a vet, and according to her the first year of a dog's life is the equivalent of about 15 "human years", the second year is 10 "human years", and each additional years is about 3 "human years", although large breeds tend to age faster and die younger, so there is no absolute standard.

I thought it was good, even though I'm usually not a huge Nicholas Cage fan. I've actually done a lot of reading on the Templars/Freemasons, and I personally don't think that they have a huge hoard of treasure, but it made for a good movie ending.

Overall I really enjoyed the movie, I liked that it made me think. It reminded me a lot of "The DaVinci Code." Dan Brown's next book, "The Solomon Key", is supposed to be set in Washington D.C. and I'm guessing it'll deal with a lot of the same topics.

What did you think of it?

Oops, sorry if it seemed like I parroted you, Lance, we must have been posting at the same time.

Yes, I saw the trailer a couple of weeks ago, first at "National Treasure" and "Christmas with the Kranks".

I think a lot of UFO sightings (light formations at night, etc) are military planes and things of that nature, and many times the governments want them to remain unidentified. (Don't think I'm conspiracy paranoid person, though, I understand keeping things under wraps while testing...). Just my two cents.
