According to the example of lizard speciation in the caribbean (watch the video above).
a) identify allopatric speciation.
b) list and explain the evolutionary forces that resulted in this type of speciation (natural selection, gene flow (migration), genetic drift, non-random mating, mutation).
c) identify cases of convergent evolution and explain your choice. base your answer on the video above.

Molecular models of two different substances are shown below. in the molecule on the left, the oxygen atom pulls on electrons more strongly than the hydrogen atoms. in the molecule on the right, the two oxygen atoms pull on the shared electrons with the same strength. water molecule, h,o oxygen molecule, oz when the two substances are put in the same container, they do not attract each other. why does this happen? a. they both contain oxygen. b. one is polar and one is nonpolar. c . they are both polar. d. they contain different elements.

In a cross between individuals of a species of tropical fish, all of the male offspring have long tail fins, and none of the females possess the trait. mating two of the f1 fish fails to produce females with the trait. explain the inheritance pattern of the trait.

In general, characteristics that an organism survive and reproduce become more common over time. what mechanism of evolution causes this?
