An alloy of aluminum is observed to have a melting range instead of a single melting point. What can be concluded from this observation? A. The alloy is a compound. B. The alloy is probably a mixture of different compounds. C. The other components in the alloy have higher melting points. D.
An alloy is a mixture of metals or a mixture of metal and another element (non-metal or metalloid). Alloys often have better properties than metals that are made. Alloys are, for example, generally harder than pure metals. They are also more resistant to corrosion than pure metals. These properties make them more useful than pure metals.
Explain the founder effect and identify the best example. a) The founder effect is an event that isolates part of a population, generating an allele frequency which is not typical of the original population. An example of the founder effect is the Amish population. The Amish population was established from about 200 German immigrants.
Researchers explain whether interactions are significant or not in the Results section. A study has a 2 × 2 × 3 within-groups factorial design. This example has a total of twelve cell (s). Researchers would need to investigate three main effect (s), three two-way interaction (s), and one three-way interaction (s) in this study.
