no, i couldn't send an image to my classmate for a project, so i uploaded it here and sent him the link. thanks though.

Can't paste picture into message, so displaying link to get to picture.

I don't know how to phrase this as "help" instead of an "answer." A suggestion would be to look at the way these specific groups give birth. One of them lays eggs, gives live birth to mature children, and lastly one of them gives birth to live, premature young and raises them in a pouch. Similarities? They are all mammals and keep their blood temperature stable within their own bodies.

I had actually been wondering about this. The hype about it seemed to have some fairly convenient statistics, and fairly vague symptoms. With all of the back and forth over the web, I couldn't make a decision as to whether it was real or not.

first one that comes to mind. http://askville.amazon.com/Neurosyphilis-affect-brain-body/AnswerViewer.do?requestId=15159307 i don't think there is a comprehensive list of diseases that affect sensory perceptions, but i will keep looking.

but do to non science "magic," the waste products disappear. So i assume that they aren't factored into the equation.

well. This is an interesting scenario. I would have to say... that it would smell like the smell of the bacteria. If all the waste is expelled by "magic" as it's produced, and this bacteria decomposes the milk completely, including the proteins and lipids, then that leaves nothing behind except bacteria. Taking your experiment at face value, that should be the answer.

I read this and imagined someone mainlining mercury in hopes of heightened abilities.

The most common, I would have to say, is PTSD (Post Traumatic Stress Disorder). Symptoms include flashbacks, avoidance of triggers to said flashbacks, inability to feel emotions, detachment, and sometimes suicidal tendencies. For the most interesting, I would have to say Post-Abortion Syndrome. It involves some of the weirdest symptoms I've ever heard of, and also has a large stigma around it (abortion in general).

the molting definitely doesn't go all the way through to the skin. Just because of the fact that they live in Antarctica, I would have to say showing bare skin would be a fatal flaw for the penguins.

I definitely don't have any suggestions. Pretty much out of my league at that point. I know diseases that affect sensory perception, if that's what you're asking?

I assume you can tell the difference between the two, so i'll just post the picture. From what i can tell, there are close to the same size, but it looks like the rotifers are consistently smaller. Tardigrades win in the cool contest, though. At least in my opinion.

Nice list. To answer your question, thirst and hunger are not outside stimuli producing sensory reactions, so they are not technically senses.

Well, in a natural selection sense, yes. By introducing a species into an environment only some of its population is suited to, you can speed up the evolution process in favor of the suited phenotype. This is called directional selection, or the gradual shift of a population into a suitable phenotype based on the entire groups genotype.

I cast my vote for this thread as being the best thread ever.

the first one is the easiest to perform and replicate, so i would definitely choose that one.

btw, humans apparently do not have a fast block mechanism.

Its in chap 46 of my AP Bio book. It has two parts, the fast block and the slow block. The fast block is at the end of the acrosomal reaction, when the sperm fuses with the egg's cytoplasm. this causes the ion channels to open up and release sodium ions to flow into the egg and change the membrane potential. This change is called depolarization, and it occurs within 1-3 seconds after the sperm fuses with the egg. The second part is called the cortical reaction. since the depolarization only lasts a few minutes, it only blocks sperm for a short time. Numerous vesicles lie just beneath the egg's plasma membrane, in the rim of the cytoplasm called the cortex. within seconds of the fusion, these vesicles, called cortical granules, fuse with the egg plasma membrane, initiation the cortical reaction. cortical granules contain a treasure trove of molecules, which are now secreted into the perivitelline space, which lies in between the plasma membrane and the vitelline layer. the secreted enezymes and other macromolecules together push the vitelline layer away from the egg and harden the layer, forming a protective fertilization envelope that resists the entry of additional sperm. another enezyme is released which clip the remaining sperm receptor proteins. whew. now you know, lol.

my teacher showed a way of doing this, using rounding 2+2=5 2.4+2.4= 4.8 round it up and down 2+2=5 2.4 is rounded down to 2 and 4.8 is rounded up to 5.

Merry Christmas or Happy Holidays all

never mind then, lol

Are you in AP Biology? Thats the chapter we just finished.

From what i can tell, i don't think there are any mitochodria in the ovum cell itself. http://www.merriam-webster.com/art/med/ovum.htm

It's not about winning. It's about changing opinions:cool:

its easier to change someones opinion if they know the subject matter. Arguing with an ignorant person is frusterating, since they don't know enough about the subject to form a legitimate arguement.
