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:
--> they are golden brown
--> they possess assimilative cell with indented waist.
--> they possess large nucleus with visible chromosomes.
It has been reported that many dinoflagellate species can produce various natural toxins. These toxins can be extremely toxic and many of them are effective at far lower dosages than conventional chemical agents. Therefore the option, Some produce toxic agents in the water, is a correct statement.
 
        
             
        
        
        
He wanted to see how different traits passed through the pea plants he grew. To do this, he needed to cross polliante so that their were multiple parents affecting the genes of the new pea plant. If he self pollinated, all the new baby pea plants would Look the same as their parents and we wouldn't know as much as we do about genetics now

Answer:
Although it has some good effects it can also harmfully reduce human diversity and increase social inequality majority of genetic editing is pretty bad. 
It probably shouldn't even be allowed because it can cause risks to future children, creating new forms of discrimination. This can also make people lose their trust in science technology.
New toxins can be produced, Gene Transfer to Wild or Weedy Relatives, change in Herbicide Use Patterns. There are most Unkown harms yet to be discovered.
