Answer:
By providing an example using one organ for each of the four levels of complexity, we have the following:First level organ: Skin; this is because it takes up a few cells. Second level organ: Windpipes; this is because they have more complex shapes with multiple cells. Third level organ: Stomach; this is because the stomach has to act on demand instead of a flow. Fourth level organ; Heart. The reason it is difficult to make level four organs in a lab is that it has a complicated architecture with several cells, blood vessels and tiny capillaries included. So far, scientists are yet to fully develop solutions for the level four organs and hence, difficult to create in a lab.

Explanation:
Answer:
The correct answer will be- in coupled and coordinated manner.
Explanation:
Cellular respiration is a complex process which involves the breakdown of the sugar molecule to provide energy in the form of ATP. The process takes place in the four stages: Glycolysis, Krebs cycle, link reaction, Krebs cycle and the electron transport chain.
These stages are interlinked to each other as the product and intermediates of one set of reaction act as a substrate to another set of reactions like the pyruvate of glycolysis acts as a substrate in the link reaction. Also, the NADH formed in glycolysis and Krebs cycle is used in the electron transport chain.
Thus, in a coupled and coordinated manner is the correct answer.
