Use this information to answer the question(s) below. suppose an experimenter becomes proficient with a technique that allows her to move dna sequences within a prokaryotic genome. if she moves the promoter for the lac operon to the region between the beta galactosidase (lacz) gene and the permease (lacy) gene, which of the following would be likely? the three structural genes will be expressed normally. rna polymerase will no longer transcribe permease. beta galactosidase will not be produced. the operon will still transcribe the lacz and lacy genes, but the mrna will not be translated.

After reading the paragraph below, answer the questions that follow. researchers have created a robot that has a very thin leg that is moved by cardiac (heart) cells contracting in unison. the robot, made of a polymer similar to that used in making contact lenses, is bathed in heart cells with supporting cells, which then attach to the robot and provide movement as they contract. all of the cardiac cells working together can cause the robot leg to move in a way that individual cells could not. this is an example of a. emergent properties of cells. b. energy flow through an ecosystem. c. adaptation. d. internal environment regulation.
