List the three types of eyes that have evolved among animals. how does image formation in each eye
differ?
a. explain why accommodation of the lens occurs.
b. how can abnormal eye conditions be corrected?
c. what are rods and cones responsible for? explain how rhodopsin and photopsins contribute to the
process of vision.

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

golgi body just took the test on edge

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
