A researcher is planning an experiment to engineer a nonfunctional version of an RTK. Which engineered protein will most likely be a nonfunctional RTK? an RTK protein with a second enzyme region in the cytosolic portion of the protein,

an RTK protein that can phosphorylate itself even in the absence of the signaling molecule,
an RTK protein that is unable to bind to the signaling molecule,
an RTK protein that has multiple phosphorylation sites

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
