Building models doesn't actually help scientists observe phenomena. Scientists build models to describe how nature and systems operate then make observations to see if their models match what they observe. Models which don't match what they observe are either alterated or scrapped. Good models are kept and used by the scientific community.
Answer:
A plant cell
Explanation:
In the given question, a stage of a cell has been described during cell division.
The characteristic of this cell division are:
1. Nuclei are formed at opposite poles- shows that it is the stage of cell division
2. The formation of cell plate- the cell plate is formed in the middle of the cell which indicates that the cell is a plant cell.This cell is a plant cell as the cell plate is formed only in the plant cells and not in the animal cell in which the contractile rings are formed.
Thus, A plant cell is correct.
In cellular respiration, the cells take the carbohydrates in and through complex metabolic processes, they break them down and release the energy.
Water had the capability to hold up the thin overhang of the underground.
When water is depleted, there is nothing to support this overhang, which eventually led to the formation of sinkholes.
As for the collective behavior, it's all because of the scarcity. Water is one of human's basic needs to survive. When water is scarce, this will force the people to compete with one another to obtain it, which will cause the behavior
