I don't know how you could capture a queen from an ant colony near you, but you can order commercial ant farms from the internet, and those will come with a queen. They aren't too expensive either, if I remember correctly.

Well, the diaphragm controls whether or not the lungs contract or expand, which expels and draws in air respectively. Chemoreceptors gauge how much CO2 there is in the lungs (the urge you get to breathe while holding your breath comes from the buildup of CO2 in the lungs, that's how the body measure...

There's nothing wrong with applying scientific principles to something that you'd like to verify. If you think that the Bible is an accurate record of what happened, then by all means test away at it. What I have a problem with is when the tests are done improperly, or when the tester has a strong b...

The photoreceptors get locked into patterns when the eye stares at them for a long time-- like if you watch a spiral spinning for a while, and then quickly look somewhere else, you'll still see that swirling pattern for a moment.

Here's how this kind of problem works. Each parent are carriers for albinism, which means that they have the allele for the trait, but don't express it (which means that their genotype would be Aa). This means that each parent has a one in two chance of passing on the albino allele to any offspring ...

The easiest way (in my opinion) to fill time on a topic like evolution is to pick a very specialized animal. For example, if you talk about bats, you can describe how flight evolved for them, and how echolocation evolved, etc. This lets you talk about a lot of specialized structures, and also lets y...

Disruptive camoflauge is the only one I've ever heard, the stripes confuse a predator which stops them from being able to pick out one zebra from a herd. But I guess I don't really know for sure.

I've almost always seen sex linked in reference to the X chromosome, since so many more sex linked issues can appear on the X chromosome. But technically sex linked means any allele that occurs just on one sex chromosome. But yes, the answer is E (this is a classical example for sex linkage brought ...

No way, I'm terrified of spiders! Dissect as many as you want, just keep them all away from me!

And yes, I'm a bit confused too... what would you dissect that wouldn't be an organism, but would be on a biology discussion board?

Sure. A phenotype is just what trait is expressed in an organism. For example, I have brown hair, and so I display the brown hair phenotype. Genotype is just the gene combination of an individual. Let's stick with hair for an example: My phenotype is brown, but that could be the result of different ...

I see. Well I apologize for my (second) misunderstanding. But I still don't think that HGF has any particular effect on evolution, aside from providing more combinations of things to be affected by natural selection.
