24) If the three genotypes (A,B, and C) had been placed in a different pond in a different location, the genotype with the highest fitness would be: 25) Evolution causes phenotypes to change over time because: a) Those phenotypes that code for genotypes that are better gene transport machines will eventually predominate in a population b) Those genotypes that code for phenotypes that are better gene transport machines will eventually predominate in a population c) Survival favors the fittest d) Genotypes with the highest survival have an advantage e) Phenotypes with the highest survival have an advantage 26) Consider the life-cycle of the HIV virus. If a new drug was developed that prevented the CCR5 protein from being produced in a cell, then: 27) If a genome of the HIV virus could be constructed that had no Adenosine nucleotides (i.e., no A, recall that A pairs with T) then, Consider the evolution of an agricultural pest in response to a pesticide. It is common for resistance alleles (i.e., gene forms that protect against the harmful effect of the pesticide on the pest) to be strongly selected against when the pesticide is not present in the environment. This occurs because the resistance allele protects against the pesticide but does not carryout its original function properly. Nonetheless, the resistance allele has a net selective advantage when the pesticide is present in the environment because protection from the pesticide more than compensates for its other harmful effects.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
