What plant and animal breeders process artificial selection?Selective breeding is the practice of pairing parents who share particular features in order to produce offspring who have a greater number of desirable traits. Humans have carefully selected a wide range of plants and animals for thousands of years, including agricultural species with higher yields.
Instead of allowing the species evolve spontaneously without human involvement, as in natural selection, people chose animals or agricultural products based on desirable qualities, a practice known as "selective breeding,” or artificial selection.
Therefore, The breeders choose organisms with the most desirable traits and breed them.

which term describes water that picks up chemicals and pollutants as it moved over driveways, streets, and lawns?
A) septic water
B) runoff water
C) pure water
D) arctic water
Answer:
A or B
Explanation:
a) The term "septic" refers to the anaerobic bacterial environment that develops in the tank that decomposes or mineralizes the waste discharged into the tank.
b) Runoff is nothing more than water "running off" the land surface. Just as the water you wash your car with runs off down the driveway as you work, the rain that Mother Nature covers the landscape with runs off downhill, too (due to gravity). Runoff is an important component of the natural water cycle.
