Novosadov [1.4K]

Answer:

The correct answer is b.Amplify the gene using PCR. Insert the gene into a plasmid vector. Transform the vector into the bacteria.

Explanation:

If I have a very small amount of gene for a fluorescent protein than the first step is to amplify the gene so that appropriate protein can be produced. PCR is the instrument that is used to amplify the protein.

So after amplification of the gene, the plasmid vector will be used in which the gene will be inserted because the plasmid vector is used to insert this gene in host cells where protein will be expressed.

The final step will be to transform bacteria with recombinant plasmid so that plasmid can make its copy and express a fluorescent protein in bulk.

Vinil7 [7]

Answer:

In an ecosystem photosynthetic plants act as producers wheres other organism act as consumers.

Explanation:

Green plants undergo photosynthesis to produce their own food as a result they are called producers and are placed in the first tropic label of energy pyramid.

          The other organism that intake green plants are called primary consumers for example grasshopper. The primary consumers are placed in the second tropic label of energy pyramid.

           The other consumers are termed as secondary consumers or primary carnivores that feed on primary consumers For example Snake because it eats grasshopper and is placed in the third tropic label.

         Finally the tertiary consumers or secondary carnivores consumes secondary consumers to intake energy from them.For example Hawk eats snake,as a result hawk act as secondary carnivores and are placed in the top of the energy pyramid.
