Answer:
Function:
mRNA: mRNA can be described serves intermediate molecule between the genetic material and the amino acids for the making of protein.
rRNA: It makes up the ribosomes along with the ribosomal proteins. Ribosomes are the sites where the process of translation occurs.
tRNA: The tRNA is involved in the bringing of the nucleotides to the ribososmes for translation.
D.)The enzyme changes shape and no longer fits the substrate.
High temp causes enzymes to speed up the reaction but too much heat and the enzyme might denature, losing its shape.
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.
The answer is B and D i learned this in biology last week
