If you weigh 48kg on earth. What would be the weight on the moon?

You would weigh 8kg.

Explanation:

Since the moon only has 1/6 of the gravity than Earth does, It means you would weigh 6 times less than your original weight on Earth.

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).
