Echolocation is an adaptation bats use to
a.
hunt insects in flight
b.
locate flowering plants
c.
find warm places for hibernation
d.
all of the above

The answer is d. all of the above. Bats use echolocation, a high-frequency system, to fly around and to hunt. Echolocation helps them to hunt insects in flight, to locate flowering plants, and to find warm places for hibernation. Bats' call is pitched at a very high frequency (up to 110 kHz) that are too high for humans to hear.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

okay now i don't know this but for the pints nothing else to say bye
