After mixing a heat-killed, phosphorescent (light-emitting) strain of bacteria with a living, nonphosphorescent strain, you discover that some of the living cells are now phosphorescent. which observation(s) would provide the best evidence that the ability to phosphoresce is a heritable trait? a) dna passed from the heat-killed strain to the living strain. b) protein passed from the heat-killed strain to the living strain. c) the phosphorescence in the living strain is especially bright. d) descendants of the living cells are also phosphorescent. e) both dna and protein passed from the heat-killed strain to the living strain.

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.
