Evaporation uses energy, and this heat energy is taken from the body.
A DNA test would fit this situation best. If the male samples are related, it will show up in the DNA test results.
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.

A. 1.2
Explanation:
Normally, a human body cell contains 46 chromosomes - 23 inherited from the father and the same number from the mother.
Most of the human DNA, or human genes, are located in the chromosomes.
Each metaphase chromosome consists of:
two sister chromatids containing one DNA molecule each, and since they are formed by replication, these molecules are completely identical in gene content; that is why chromatids are called sister chromatids; two centromeres, one on each chromatid.
