Studies have been conducted on synthetic products, including DDT and estrogen. The use of these synthetic products has been discontinued due to increased risk of cancer and other health concerns. Genetic engineering has increasingly been used in cattle, crops, and pharmaceuticals. The long-term effects of genetic engineering have not been studied at this time. What risks, if any, are there to using genetic engineering in food and medicine?

The right answer is c.sandstone.

It might. it might because if you think about if they discovered if we came from (lets say something funny like aliens) and thy found cells that matched and they would have t do more research about it but would most probably change their theory.

Here is your answer:                                                                                                                                                                                                                                                   formula for volume: base*width*height=                                                                                                 5*2*10=100                                                                                   your answer is 100cm.
