    b. most likely to reproduce.

    56. microevolution is the term that applies to which of the following?

    None of these. It's basically a change in allele frequencies in a population that does not result in speciation. If I had to choose, I would reluctantly pick

    d. small scale changes over a short period of time

    57. which of the following lists the levls of taxonomic classification in order from the most inclusive to the least inclusive?

    d. flagellated sperm

    63. conifers such as pine trees are

    e. gymnosperms

    64. which of these wouldb e best able to reproduce during a period with only light rainfall?

    Sorry, I'm not going to choose between these three. The idea is that they have flagellated sperm that need an environmental moisture film to swim through.
