Charles Darwin noticed that among the same species there were variations in traits based upon geographical location. These changes may have evolved from climate differences, predator/prey relationships and food sources. This particular experiment was intended to duplicate natural selection by demonstrating the concepts with artificial selection. The result was that over time, new traits could be bred for. Although there may be more than one correct answer here, the best answer is the first; desirable traits can be selected and bred in offspring.
Answer:
B) Curve B represents how water takes longer to heat and longer to cool.
Explanation:

Hey there! Let's solve the problem:
CD4 T cells activate CD8 T cells through an underhanded cycle including an antigen presenting cell (APC), customarily a standard dendritic cell (DC). An APC presents a peptide to a true CD4 T cell through a Class II MHC molecule.
