Small islands can form during the constructive process called

a) erosion.
b) glaciation.
c) deposition.
d) weathering.

C) deposition.

Explanation:

The deposition is the result of the natural or anthropic wear process that acts on the rocks and also on the soil, where pieces of the rock are released and deposited elsewhere.

The sedimentation process occurs due to the exposure of solid relief structures to external or exogenous agents of surface transformation, also called weathering agents such as water, rain and climate change. Sediments (pieces of rock) when deposited in their new environment can, in addition to forming soil, form small islands.

"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."

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project
