Question

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. organelle
b. organism
c. organ system
d. tissue

Answer 1

Answer:

Tissue

Explanation:

A cell is a structure formed during the evolution which contained all the molecules and favourable conditions required to survive and therefore acts as the functional and structural unit of life.

In evolution, more than one cell aggregated together to form a structure which could perform much complex function than a single cell called tissue as they are programmed to perform the same function.

In the given question, since the heart cells worked together to cause movement in the robot therefore the cardiac cells formed cardiac tissue or heart.

Thus, the tissue is the correct answer.
