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.
-If the creators of the robot wanted to provide evidence that it is alive, which of the following properties would be best to use as evidence?

Question

Quizplus · Accepted Answer

The requirement for a liquid medium to provide nutrition for its cells suggests a biological process of metabolism, which is a characteristic of living organisms. Movement alone (A) does not imply life, as many non-living systems can move. Reproduction by researchers (C) is not a biological process of the robot itself. Having different types of cells (D) indicates complexity but does not directly evidence life without showing biological processes like metabolism, growth, or self-replication.
