Which must be kept in mind when determining if an explanation is correct?
MatroZZZ [7]

Answer:

C. that there may be more than one way to interpret data

Explanation:

When determining if an explanation is correct you must always remember that there may be more than one way to interpret data. Depending on the context that the explanation is being used in or who is reading it, the explanation may be interpreted in two completely different manners which may be far off from the original intended explanation. This can therefore completely nullify or maybe even expand the original determination.

Claytonia virginica is a plant with flowers that vary from white, to pale pink, to bright pink. Slugs prefer to eat pink-floweri
exis [7]

Answer:

The frequency of pink flowers will increase to near one over time, while the frequency of white flowers will decrease to near zero.

Explanation:

There are two forces acting as selective pressures.

  • Slugs prefer to eat pink-flowering over white-flowering plants → selective pressure against the pink genotype → plants with pink flowers suffer from severe herbivory and are more likely to die.
  • Bees prefer to pollinate pink over white flowers → selective pressure favoring the pink genotypes → Plants with pink flowers produce more seeds than plants with white flowers.

When the researcher removes all slugs from the study population, he/she eliminates the selective pressure against the pink genotype, leaving only the force acting in favor of the genotypes. So plants with pink flowers will produce more seeds that will originate more plants with pink flowers. As there is no predator over these plants, they will keep reproducing and growing pink flowers. Over time, the frequency of the pink genotype will increase, while the frequency of the white genotype will decrease.
