What difference does it make in the organism's physiology/metabolism whether oxygen binds reversibly or not? Ignoring the fact that hemocyanin is only in hemolymph and not red blood cells (as in humans), my guess would be no. Hemoglobin exhibits cooperativity, so that the binding of one oxygen molecule increases the affinity for other oxygen molecules. This leads to the sigmoidal oxygen saturation curve, allowing for more efficient dissociation of oxygen at target locations. |

Preferred Aspect Ratio for Human Eyes @AlanBoyd I think you're right. For some reason, I was probably thinking about ptosis, when a drooping eyelid does limit your visual field. |

Preferred Aspect Ratio for Human Eyes I have to agree with Kal, but mainly about #1. Essentially, the eyes are next to each other, and this allows for stereoscopic vision. If you cover one eye, your field of view is more or less circular (due to the retina and macula), but you'll lose depth perception. Plus, your eyelids slightly limit the amount you can see in the up-down directions. |

Multi-nucleated cells: advantages and examples? Technically, all the granulocytes (neutrophils, eosinophils, and basophils) have multiple lobes/segments, not multiple nuclei. Syncytia in cardiac muscle cells is important for coordinated contraction. Not sure about the rest.. |

Differences between antibiotics and antibacterial Just to add to your answer: bacteriostatic agents slow down the growth of bacteria, whereas bactericidal agents kill it. |

What phenotypes can arise from gender-related aneuploidy? @Luke Tried to answer some of your questions in the edits. I'm not sure about the cognitive problems though :( I hope someone else can add to it. |

What phenotypes can arise from gender-related aneuploidy? I added a little more detail. I'm not sure how 47, XXX individuals are taller, but I can see that the extra Y in 47, XYY individuals make them more masculine. Just a guess though. I'll see if I can find more info about how these disorders cause their cognitive and developmental effects. |

What kind of fruit is this? Soda Hall? :P Oh, I remember those days... Anyway, my first thought was also a lychee/litchi. But I thought the fruit is usually whiter and there's usually a seed in the middle.. |
