The color red can indicate a positive result
Answer:
For example, addition of an orange chromic acid reagent to some compounds causes the chromium reagent to change to a blue-green color (Figure 6.37a). This is considered a "positive" test result, and in this case indicates the presence of a functional group that can be oxidized (alcohol or aldehyde).

Explanation:
todos forman parte de las características de los cromosomas. Recuerde también que los cromosomas se encuentran en las células, específicamente en su núcleo.
Microtubule – serves as a framework of the cell –cytoskeleton.<span>
</span>
Nucleus – the control center of each cell. It regulates, monitors and organizes the whole cell<span>
Since the pictures isn't given I can assume that it can be the microtubule, the microtubule is responsible for maintaing the shape and structure of the overall cell. It maintains homeostasis by permanently aiding the framework of the overall cell.
If it is the nucleus, the control center of a cell. It does a lot of functions in the cell, it helps maintain homeostasis by sending commands that the organelles do, supply energy, excrete or digest waste, regulate the movement of objects and cellular respiration, even cell division. It sustains the cell to be functional and proactive at the same time reactive to situations that is likely to occur.
