Calorie (with a lowercase “c”) is the energy needed to increase the temperature of water by one degree Celsius.
Calorie (uppercase “c”) is the equivalent to a kilocalorie (or 1000 calories)
It's probably C. Because it makes the most sense and photosynthesis doesn't make ATP and if you don't think C. Is the answer then put D.
I would say 1 and 4 are the best answers. GMO crops are clones (genetically identical) so it reduces the genetic diversity making crops susceptible to new diseases.
