Answer: The correct option is D(Some produce toxic agents in the water).
Explanation:
Dinoflagellates are found in the phylum Dinoflagellata which are single celled organisms. They are mostly found in the ocean while few of them can live in streams, freshwater ponds and rivers. The following characteristics can be used to identify a Dinoflagellates, these include:

Answer: water will move out of the animal cell causing it to swell and burst (Option C)
Explanation:
When a cell is immersed into a salty solution, the osmotic pressure generated by concentration differences of salt, will make the salt come in due to cell self-protection mechanism of the cell and water will come out, eventually the cell can burst .But since the animal cells has a higher concentration of salt and the solution has a lower concentration osmosis will take place and salt will move from higher salt concentration to lower.
