Metaphase is defined as the point at which all of the chromosome pairs are fully condensed, attached to the mitotic spindle, and aligned at the center—termed the metaphase plate.
What are the steps of metaphase?
- The chromosomes are all lined up at the center of the cell by the spindle during metaphase and are ready to divide.
- At the metaphase plate, all the chromosomes line up (not a physical structure, just a term for the plane where the chromosomes line up).
- The two kinetochores of each chromosome should be joined to microtubules coming from opposing spindle poles at this point.
- The cell will verify that all the chromosomes are at the metaphase plate and that their kinetochores are properly linked to microtubules before moving on to anaphase.
- The sister chromatids will split equally between the two daughter cells when the two cells separate in the following phase thanks to the spindle checkpoint, which is where it happens.
- A chromosome that is misaligned or improperly connected will prevent the cell from dividing unless the issue is resolved.

First of all, let's think about the scientific method, and its processes of how it works.
It all starts with observation, so we need to check all the data we have and all the information that can be collected to have a good thought on what's going on.
After gathering enough information, let's think about a hypothesis that could help solving this problem. Well, reading the question, we can check that that region passed through the wettest summer in 100 years, and that's the main problem here, because before this weather, was this disease a problem? I guess not, so this can be a reason, the change in the percentage of water in the air.
With that said, we need to test if this is true or not, and for that, we'll need mosquitoes with the West Nile virus, and we'll put them in different environments, one that it's wet, and another one that it's not that wet, just like the West Nile problem. This way we can check if this is the problem or not, if it's affecting their reproduction and etc.
Answer: system
Two or more organs working together form a system
Explanation:
A system is formed by two or more organs working together and performing similar function. For instance: organs such as the mouth, oesophagus, small intestine, pancreas, large intestine etc all joined to form the digestive system.
Thus, system is the answer
Water is highly vital to living organisms. Flora and Fauna depend highly upon it, and if the water is damaged, say through oil spills, the water will lead for harm within the environment and the flowers and native animals.
