Ginny genestudy performs the following experiment. she wants to replicate a test strand of dna using wildtype of saccharomyces cerevisiae (budding yeast) and two mutants which she calls poor-rep1 and poor-rep2. she performs the experiment with her wildtype strain, and her test dna strand replicates perfectly. she does the same experiment with poor rep-1 and discovers that this strain can only synthesize the dna strand if she adds a purified wildtype dna polymerase-a exogenously. when she performs the experiment with poor rep-2 she discovers that adding wildtype dna polymerase-a has no effect. which of the following scenarios is a possibility for the poor rep-1 and poor rep-2 strains.

scientists have discovered that hiv does not cause aids by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. researchers from the gladstone institutes have revealed that hiv does not cause aids by the virus's

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.

it should be d) transitional fossils.

they show the gradualism of evolution throughout a period of time
