Lampreys are known to attach themselves to fish. in doing so they rasp off a section of the fish with hard keratinized structures and "feed" on the blood and fluid that oozes into their oral cavity. fish can survive with a lamprey attached, but they have to expend extra energy swimming with the lamprey attached. this association would be designated a:
a) mutualism.
b) parasitism.
c) predation.
d) commensalism.

3points hurry! what is the relationship between biotechnology, sharkskin, and disease resistance? bioengineers have developed an artificial sharkskin that does not allow resistant bacteria to grow on it. disease-causing microbes have been genetically modified to keep them from infecting the skins of sharks. scientists have created a device that can be attached to the skins of sharks that dramatically increases their abilities to resist disease. sharkskin produces many chemicals that can be collected and used to create antibiotics.

Is there any solid scientific evidence that humans have been cloned?
