The dependant variable would be the salmon, because they depend on the water and pollution levels to give a result.
That would be A- Osmosis.
I hope this helps! (:
Answer:
Make sure everyone meets criteria.
Not taking supplements( As some may contain Vit D)
No tanning beds
make sure no one has a hypoactive response to vitamin d through whatever way. Injection, capsule, spray.
Check for genetic conditions or cancers like melanoma which indirectly affect vitamin d levels
Explanation:
These are some of the main things to look out for
The effect Colchicine might have on dividing cells is that the duplicated chromosomes might not be able to segregate into daughter nuclei.
Colchicine is an alkaloid that attaches to tubulin and prevents it from polymerization to microtubules. As we know that Microtubules are a component of the cytoskeleton of a cell that aids in molecular mobility inside the cell.
During cell division, chromatin condenses into chromosomes, which are then connected to microtubules. The chromosomes are separated into daughter cells by microtubules.
When these cells are treated with colchicine, tubulin polymerization to microtubules may not occur, and the chromosomes containing daughter nucleic might not be separated.

<h2>Next generation
DNA sequencing</h2>
Explanation:
CDC must use Next generation DNA sequencing method to determine the DNA sequence of the dengue virus.
The mostly used sequencing methods now a days are called Next-generation sequencing methods. They are faster, cheaper , accurate and need a small amount of sample.
Next generation sequencing platforms perform massively parallel sequencing, during which millions of fragments of DNA from a single sample are sequenced in unison. Massively parallel sequencing technologies facilitates high -throughput sequencing, which allows an entire genome to be sequenced in one day.
in Medical research where speed is necessary and sample size is small, these sequencing technology will be best to be used.
