1. What would be the percentage of the non-singing trait and female birds and generations 4 and 5 if this pattern continues? (5 points) 2. In which generation will there be almost 100% Nonsinging females if there are no changes in the bird’s environment and interactions? (5 points)

3. In what possible scenario would the female birds evolve to having the singing trait? (5 points)

Which series lists the correct order of steps of binary fission from first to last? sex pilus connects two cells ® plasmid dna is transferred ® complementary dna strands are created ® cells separate live cells bind to degraded cells ® dna is transported across the membrane ® dna is incorporated into recipient's dna virus infects bacterial cell, new viruses are made ® dna is assembled in new virus ® new virus infects another bacterial cell and transfers dna dna is copied ® dna molecules attach to cell membrane ® cell membrane elongates and pinches off ® two identical cells are produced
