Answer:

An experiment that directly test the hypothesis.

Explanation:

Although there is quite a bit missing from Mary's scientific investigation, the thing that sticks out the most is the fact that Mary is missing an experiment. Mary's hypothesis states that people would fall asleep faster if their room color were to be painted blue. To prove that her hypothesis is true, Mary would need to conduct an experiment to see whether or not she was correct.

ikadub [295]

Answer:

The correct answer will be option-B.

Explanation:

<em>Homo neanderthelensis</em> or Neanderthals are the close relatives of the <em>Homo sapiens</em> or modern humans which became extinct around 10,000 years ago.

The Neanderthals and sapiens are the two related species of the same genus Homo but they showed distinct features like Neanderthals were muscular and shorter in height compared to the <em>Homo sapiens</em>. Recent fossils indicated that Neanderthals and<em> Homo sapiens</em> interbreed in some parts of the world as they were closely related to each other.

Thus, Option-B is the correct answer.

Actual main channel depths along the river vary; with a least depth of 24' or less at a few locations at the channel edges to a maximum depth of 108' being found mid-channel at the southern approach to Hell Gate.

Due to heavy pollution, the East River is dangerous to people who fall in or attempt to swim in it, although as of mid-2007 the water was cleaner than it had been in decades.

Cladists define a species as a group of organisms sharing a set of unique, derived features that sets them apart form all other
Mars2501 [29]
For the answer to the question above, I believe the answer is the<span> phylogenetic species concept</span>.

The key to the phylogenetic species concept is that species must be "diagnosable." In other words, members of the species should share a combination of characteristics that other species don't have. To look for some unique features that define a  phylogenetic species, systematic comparisons must be done by paleontologists with other related fossils or living species
