Immunity to Small Pox
Explanation:
Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease.

However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.
Answer: Excess ethanol metabolism leads to an accumulation of NADH that inhibits fatty acid metabolism.
Explanation:
Fatty acid metabolism is often activated by limited or absence of NADH, however ethanol (the main constituent of most alcoholic drinks) on metabolism yields several molecules of NADH which rather stimulates belly/abdominal fat production often referred to as "beer gut".
The synthesis of diphenylacetylene from mesostilbene dibromide includes next reactions:
• Bromination of stilbene-it is the reaction of electrophilic adition and bromonium ion is formed as intermedier (meso compound is the product).
• Bimolecular elimination-strong base is used in this reaction (takes away the H) and pi bond is formed.
