The Amish populations in the United States began with relatively few individuals and have not recruited many newcomers to the po

pulation. Today, these Amish populations exhibit a much higher incidence of polydactyly (possessing extra digits) than other American populations. Which mechanism of evolution is likely responsible for this phenomenon

Answer: The founder effect

Explanation: The high incidence of polydactyl prevalent among the Amish population could be attributed to the a case of genetic drift called the founder effect. The founder effect occurs when a small population consisting of few people separate from a much large population, just like the Amish population separating from the larger American community. Due to the few composition or small size of the population, the genetic impact or influence on members of the population is usually higher than the effect on the larger population and leading to more rapid spread. The relatively small individuals which make up the Amish population compared to the larger American community is the reason why polydactyl hmis prevent within them and since theere are no newcomers, the trend will likely continue.

How can you reconcile this observation with the cause of death being hypoxia?
Neko [114]
Death by hypoxia can be caused by airway obstruction(strangulation) or poison(cyanide, CO).
In the case, there is a toxicology report saying the victim is poisoned by cyanide. The organ damaged also diffuse and not concentrated. Cyanide works by inhibiting an enzyme in the mitochondria that use oxygen. Therefore, the cells can't oxygen for cellular respiration, cause the tissue die of hypoxia. The oxygen is there but it can't be used. The laboratory report that found high oxygen level in the blood also supports the cyanide poisoning.

CH3OH + HOCH3 = CH3-O-CH3 + HOH Is this reaction an addition reaction or a dehydration reaction or synthesis or whatever? A. Add
bagirrra123 [75]

Answer:

B. Dehydration

Explanation:

Addition reaction is defined as the chemical reaction in which two different compunds combine together to form a new compund.

Dehydration reaction is defined as the chemical reaction in which water molecule (H2O) is removed from the reactant.

For example: RCO2H + R′OH ⇌ RCO2R′ + H2O

In the given equation: CH3OH + HOCH3 = CH3-O-CH3 + HOH

The reaction is showing dehydration because two molcules are combined aand  water molecule is eliminated from the reactant.

Hence, the correct option is B. Dehydration.
