|422: ||How do human and natural factors impact the atmosphere and weather? |
|423: || Hi! I teach an AP Environmental Science class. We are currently talking about pestilence & diseases. Our conversation turned to STDs, crabs and eyelash mites. (I know, students bring up the oddest things.) My students suddenly turned to a very odd question that is borderline appropriate but they really want to know the answer. Here it is: Do skin cells cover the testicles on a male or are they covered in taste bud cells like those that would be found on our tongue? (I guess there are websites out there & something on Tick-Tock about how the skin on the testicles are actually made of taste buds.) I hope to hear from you because this question actually got my mind wondering.... |
