HELP Which of the following atmospheric conditions are needed to create the winds?

I. Air masses with different air pressures
II. Air masses with different temperatures
III. Air masses with equal humidity

I and II
II and III
I and III
I, II, and III

the statement is true

b is the correct answer

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
