Imagine two identical plants sitting by a sunny window. One plant is exposed to the sun. The other plant is covered by a cardboard box. The box allows air in and out. The difference between the plants is that the sun can shine on one plant, but the other is in the dark. Both plants are the same temperature. Think about the chemical reactions occurring in the two plants. How would the chemical reactions occurring in the plant grown in the light be different from the chemical reactions in the plant grown in the dark?

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called

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).
