Researchers Have Created a Robot That Has a Very Thin

question 25

Multiple Choice

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?

• A) The robot can move.
• B) The robot must be bathed in a liquid medium to provide nutrition for its cells.
• C) New robots can be reproduced by researchers using the same manufacturing process.
• D) The robot has two different types of cells, fibroblasts and cardiac cells.
