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. The robot's cardiac cells, working together in synchrony, could be considered at what level in life's hierarchy of organization?
a. organelle
b. organism
c. organ system
d. tissue

d. tissue

Explanation:

There are several levels of organization of life which starts from the functional unit of life called cell.Cells are made of a combination of macromolecules that consist of atoms. Several cells associate together to perform one or more specific functions at the tissue level. The tissue level is made up of similar cells that carry out similar task or functions. The robot’s cardiac cells that work together in synchrony could be considered at the tissue level.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

you dont brother god luck
