using immunoprecipiation you can isolate a protein (protein x) you think is involved in chronic myelogenous leukemia (CML), which is caused, in part, by a hyperactive tyrosine protein kinase called ABL. You think one of the targets of ABL is the protein X that you can purify. In comparing tissues with and without the disease, you subject the samples to isoelectic focusing. Understanding how IEF works, how would you expect the samples with CML to migrate compared to the wild-type, non-diseased sample protein

Aneuron is stimulated with an electric pulse. the action potential is detected at a point 3.70 cm down the axon 0.0052 s later.when the action potential is detected 7.20 cm from the point of stimulation, the time required is 0.0063 s. what is the speed of the electric pulse along the axon? (why are two measurements needed instead of only one? )

Drag each tile to the correct location. match each trait that an organism displays to a reproductive strategy.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
