Why is genetic recombination important for species?

a. genetic recombination allows the genetic material of a cell to be copied before cell division, resulting in daughter cells that can undergo genetic recombination.
b. genetic recombination allows the genetic material to be expressed, creating both rna and proteins from a cell's dna.
c. genetic recombination allows new genetic combinations and increases the genetic diversity in a population. this drives natural selection and evolution.
d. genetic recombination allows the best genes to be selected, ensuring that mutated genes aren't passed on to offspring

In addition to seeds, which of the following characteristics are unique to the seed-producing plants? a) sporopollenin b) lignin present in cell walls c) pollen d) use of air currents as a dispersal agent e) megaphylls

Why reason best illustrates why hershey and chase chose to use viruses in their experiment?

Which of these is true of the cytoplasm of an unfertilized egg? a. it is an unevenly distributed mixture of mrna, proteins, organelles, and other substances. b. it does not contain substances that are important in directing development. c. these substances are supplied by the sperm. d. it does not contain substances that are important in directing development. e. development is directed solely by the surrounding cells. f. it is a homogeneous mixture of mrna, proteins, organelles, and other substances. g. it does not contain substances that are important in directing development. h. these substances are produced by the dna of the fertilized zygote.
