Astudent is investigating the role diffusion plays in maintaining homeostasis inside of animal cells. the student plans to place a starch solution inside of a container and place a glucose solution inside of a second container. the student will then place each container into a beaker of distilled water. after 20 minutes, the student will test the water in each beaker for the presence of starch and glucose. which of the following would be the best material for the student to use for the containers holding the glucose and starch solutions? a rubber balloon that can expand and stretch without breaking b tissue paper that will easily rip and dissolve in water c tubing with many pores that are too small to see d glass that has a flat and uniform surface

C

Explanation:

"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."
