The fossils called homo floresiensis were dated to 18,000 yBP. H. floresiensis individuals stood approximately 3 feet 6 inches tall, had tiny brains, large teeth for their small size, shrugged-forward shoulders, no chins, receding foreheads, and relatively large feet due to their short legs. They made and used stone tools, hunted small elephants and large rodents, coped with predators such as Komodo dragons, and may have used fire.
Answer:
The information is not sufficient to support this asumption
Explanation:
To unequivocally determine the existence of selection acting on this trait (size), it is necessary to carry out an experiment in which the sample size should be statistically significant (N sample for each group > 50). Moreover, it is also important to include negative controls (i.e., individuals with an average size between both groups) in the experiment.

Answer:
The original water sample contains 830,000 cells per milliliter.
Explanation:
A sample of well water is tested for its bacterial content in a plate count assay. A one-milliliter sample of the water is diluted in a 1:10 dilution series. One milliliter of the fourth dilution tube is plated in a pour plate. After incubation, the plate has 83 colonies, indicating that the original water sample contained 830,000 cells per milliliter.
