How would homeostasis be affected if the endocrine system did not release the proper amount of hormones? i need the answer asap

Homeostasis is basically balance in your body. The endocrine system releases hormones to maintain homeostasis. If the proper amount of hormones were not released, homeostasis would not be maintained. Or in other words your body levels would not be balanced.

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).
