We see here a method of asexual reproduction, binary fission, in which one organism splits into two separate organisms. In other organisms, part of an individual separates and forms a second individual. This process occurs in many asteroid echinoderms through splitting of the central disk. This type of reproduction is analogous to growth in humans because relies on the process of

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.
