Which statements accurately describe carbon? Check all that apply. Carbon has fourteen valence electrons.
Carbon forms millions of known compounds.
Carbon can only form single covalent bonds.
Carbon bonds with oxygen, nitrogen, sulfur, and phosphorus.
O Carbon bonds with halogens such as chlorine and iodine.

Carbon forms millions of know compounds.

Explanation:

And it is also right about Carbon bonds with oxygen, nitrogen, sulphur and phosphorus.

Carbon is the only element that can form many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just right, small sized to fit in comfortably as parts of very large molecules.

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).
