- describe how electrofishing worksarrow_forwardwhen we collect fish or mussels we record a variety of biological information, including but not limited their sex, length, weight or a scale or finray or other tissue sample. Why do we do this, and what information are we hoping to obtain from these measurements and taking these samples?arrow_forwardDraw a rough sketch of the control and experimental data using a normal dose/response curve plot: i.e. % of total bound ligand vs. concentration. Indicate Kd and Bmax on this sketch. You don’t need to use exact numbers, but the relative proportions should be closearrow_forward
- Name something that could be happening to glutamate transporters that could have this effect on glutamate transport (i.e. the difference in glutamate transporters between control and experimental conditions).

If a long, red radish plant is crossed with a round, white plant, what will be the appearance of the F1 and F2 generations?arrow_forwardNonearrow_forward
- Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…arrow_forwardQuestion #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:arrow_forwarda. What percentage of a drug is eliminated after 4 half-lives? Please round to the nearest percent. b. What will happen to elimination of the drug in the previous question if the system is saturated? explain and show any math involvedarrow_forward
