Answer the following questions:

1. Describe the experiments that need to be done in order to determine the LD50 and what a chart would look like (sketch this out and label axes and important points)

1. An LD50 value is the best measure available to indicate the potential for a compound to cause harm, to be toxic. However, there are six limitations that we looked at and explained. Below, using your own words, name each of these limitations and explain in detail (and with an example/scenario if possible) why it’s a limitation.
