comment Human female chest model or data representation?
What is the purpose for (ostensibly) a breast model? These are commonly used in radiotherapy models but I am not familiar enough to point you to a data source.

comment Is there differences in components of saliva among species
Some functions stay the same. For instance, at least in mammals, saliva helps to lubricate food for swallowing, begins digestion of starches by amylases and provides a liquid medium in order for taste sensation to funciton. More broadly conserved in animals is the inclusion of antimicrobial peptides in the saliva that function as a primitive immune function to keep the oral cavity clear of harmful microbes.

Not to nitpick, but venom is technically injected and is not a normal component of saliva. Toxins on the other hand are completely normal.

comment What cells don't have a primary cilium?
Hi, if you found my answer acceptable, it would be a nice gesture to show this by marking it as accepted.

comment Why aren't we allowed to refreeze previously thawed breastmilk in refrigerator?
Something to note is that the thaw and refreeze cycle is not just about texture, but there is real damage happening to the proteins that are present in the milk. All the good things that make breast milk useful for infants (growth factors, hormones, antibodies, etc) will be destroyed by freeze-thaws.

comment Why do our eyes close when we sleep?
Why should there be more? Sleeping causes a state of paralysis, so it's better if the eyelids remain closed than open. Not to mention enviromemtal light directly modulates sleep/wake cycles, arguing again for closed being the preferred state for sleeping.

comment Why do our eyes close when we sleep?
Can you explain that? The points I've raised are matters of physics and physiology.

comment Exocytosis of mast cell secretory granules
I would say a complete answer warrants a literture review on the topic and you're not likely to get all the details here.

comment Gene perturbation, what is it used for, explain to computer scientists?
I'm not sure how you can explain it by microarray, since a microarray only gives a readout at a transcript level, and genetic purturbations can be applied down-stream at a protein level (say by expressing a mutant protein). Also, perturbation studies in vitro are quite diverse as terdon already mentioned. I would suggest reading literature for the types of questions you wish to answer, and see how they were addressed experimentally to better focus your question.

Fragile corneas are a requirement for our vision. Thick corneas are much less fragile but then attenuates more light.
