Researchers have been studying a rare population of 87 voles in an isolated area. Ten voles from a larger population were added to this isolated population. Besides having ten additional animals, what benefits are there to importing individuals?

#Unit 9. Diversity of Life Forms
  1. There is no benefit other than increasing the overall population size.
  2. Additional voles will strengthen competition and increase the survival of the fittest.
  3. Additional animals would increase beneficial genetic drift.
  4. Additional voles from a distant population will likely increase genetic diversity and reduce inbreeding.

Some of the statements regarding competitive inhibition are given below
a)  The effect of a competitive inhibitor depends on the inhibitor concentration, the substrate       concentration and the relative affinities of the substrate and the inhibitor for the enzyme.
b) if the substrate concentration is low, the degree of inhibition will be great.
c) the substrate concentration is high, then the degree of inhibition will be marked low
