Which statement describes a positive effect of selective breeding? A. Selective breeding can result in a decrease in the genetic diversity of a population.
B. Animals bred by selective breeding are more likely to have some health problems.
C. Animals bred by selective breeding are more likely to have traits that are useful to people.
D. Selective breeding can make some undesirable traits more common in a population.

The answer is C

Explanation:

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
