List five response variables that should be determined in a callus induction experiment

Report the chi-square statistic value State the degrees of freedom We are only looking at F1 cross 1

Design a simple, manipulative experiment to test the hypothesis that synthetic fertilizers in the environment influence the population density of the salamander, Ambystoma tigrinum.  Your experiment can have no fewer than two treatments and no more than four. State your hypothesis. Briefly describe your experiment. Address the following: Is it a field or lab experiment? What are the treatments, how are they set up, and what differentiates them? How many replicates of each treatment will there be? What are the standardized conditions of your experiment? C.  Identify the independent variable, including units, in your experiment. D.  Identify the dependent variable, including units, in your experiment. E.  Identify at least one control treatment and explain its specific role in the experiment.

Please make a dichotomous key for the following animals ginger cat, falcon, husky dog, and brown squirrel

L Describe at least five conditions required for the Hardy-Weinberg principle to be true. Explain why these are not realistic and provide examples where possible.

These results show how many cells of each type of yeast showed mating structures after being exposed to three different yeast mating pheromones. For each yeast cell type, a group of 1000 cells were given the Wild Type-created pheromone. Then, another group of 1000 cells were given the Variant 1-created pheromone, and then another group of 1000 cells were given Variant 2-created pheromone. The same concentration of pheromone was given to each group. After 48 hours, the cells were observed. Cells that had differentiated by showing mating structures were counted. A) Identify a signaling molecule from the model presented. Explain how receptors play a role in cell differentiation. B) Identify the dependent variable and two controls the experimenters used when conducting this experiment. C) Evaluate if the number of Variant 1-Type cells with mating projections was significantly different from those of the Wild Type. Use chi-square analysis. D) Scientists propose that a mutation has occurred…

The study by Wakefield et al. that purported to show a link between autism and the MMR vaccine was published in a peer-review journal. Later, it was retracted, which means that the journal's editors thought that the study shouldn't have been published. Which of the following were problems with the study? (a) There were important potential confounding variables, because the groups with and without the vaccine were recruited in different ways. (b) It contained lies. (c) It did not disclose that Wakefield's conflict of interest that he was involved in suing vaccine companies. (d) All of the above

plants were grown using two differenc fertilizers and the number of flowers that each plant produced was counted. to test for a significant effect of fertilizer on the number of flowers at the 5% level significance, the calculated and the critical values were computed. type both the null and the alternative hypothesis for this test in the box below. use full sentences to describe both H0 and H1. (no mathematical terms in the answer)

In summary, what are the main arguments on the limitations of biological determinism?

Use the computed values for reference
