A researcher studying llama genetics would like to clone her gene of interest into the pUC19 cloning vector using the blue-white screening approach we discussed in class. Below are the vector and llama DNA fragment to be cloned into the vector. The restriction enzyme sites indicated on both DNA molecules. Which restriction enzyme should she use in order to get the largest possible DNA fragment cloned into the vector

In a vegetable garden 45 bean plants have been eaten by deer 5 are untouched what is the frequency of bean plants in the garden that have been eaten?

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
