According to the law of conservation of energy, which changes would decrease the total energy of a system? A. An addition of 200 J of thermal energy and a loss of 350 J of kinetic energy B. An addition of 500 J of thermal energy and a loss of 250 J of thermal energy C. An addition of 400 J of GPE and a loss of 350 J of thermal energy D. An addition of 300 J of kinetic energy and a loss of 250 J of thermal energy

straight probes are used primarily for measuring flow as it is approaching the test area. its geometry allows the probe to be mounted so that it is in the direct line of airflow.

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).
