Having a mutated gene ce30 on chromosome 3 that is expressed results in CEL disease. The gene ce30 undergoes imprinting in the paternal lineage. A father, Marvin, does not have the disease and does not have mutations in either copy of the ce30 gene. The mother, Jill, does not have the disease but does have one copy of a mutated ce30 gene. They carry out genetic testing on their unborn son and learn that the fetus has inherited one normal copy of ce30 and one mutated copy of ce30. Will this son have CEL disease

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.
