Which the following statement is FALSE?

a. Relative water content is not a very sensitive index because leaves can show strong responses to <2% change in RWC
b. Relative water content is not a very sensitive index because it gives no information about the forces for water movement
c. Relative water content is equal the ratio of the mass of water in a given leaf over the mass of water when that leaf was fully saturated
d. Relative water content is equal the ratio of the mass of water in a dry leaf over the mass of water when that leaf was fully saturated

sodium i think the chemical element of atomic number 11, a soft silver-white reactive metal of the alkali metal group.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.

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).
