In Biology we learned about how the different sensory organs in the body require balances of different ions to function. For example, the inner ear has a membrane full of K+ rich fluid. Can we infer then that a lack of needed ions in the body then causes a decrease in senses?	4
If Clade Ecdysozoa are the one of the most common clades on earth and molt continuously, why do we not find shed exoskeletons more often than we do?	1
I work in a Donor Tissue Lab where 80-90 percent of my donors are recorded as having died between 1-4 AM. Is there any correlation between these hours and being more likely to die in your sleep of a preexisting illness?	1
Given that some animals, like dogs or primates, copy human’s altruistic or malevolent behavior and become ‘more like us’ in their behavior. Can we infer then that other animals that are vastly different can copy each other’s behavior in a similar way?	1
A textbook I read stated that the randomness of mortality rates of some animals, like birds, is related to their size. The book listed the example of a sparrow having a randomness to the point where they just drop out of the sky. What other animals have similar statistics related to their size?	1
Is reproductive success measured by the number of offspring that are born living or by the number of offspring that survive past infancy?	1
When I build a pool in my backyard and algae begins growing within days, where did the algae come from? Do the spores float on the air or are they present in the water I filled it with?	1
When did we begin transitioning from naturally occurring ingredients in soaps, shampoos and other household hygiene items to ingredients like ‘cocamidopropyl betaine’ and ‘iodopropynyl butylcarbamate’ and what influenced this shift in manufacturing? [Common ingredients on a shampoo bottle]	1
Why are people concerned about someone collecting their DNA through 23andme or at the doctor? What can someone do with your DNA other than catching you committing a crime?	1
How can certain responses to sounds in nature be passed down genetically in some animals with no prior exposure?	1
