Answer:
d. a bacterium with human gene for producing insulin
Explanation:
Transgenic organisms are the organisms in which the foreign DNA is introduced by using the molecular techniques for obtaining a particular result. This foreign DNA can be introduced using a vector called plasmid vector.
One of the examples of transgenic organisms is E.coli with the human gene for producing insulin. So for producing artificial insulin, the gene which produces insulin peptide is ligated in a plasmid vector and then this plasmid is introduced in the bacterium where this plasmid replicates and produces insulin. So the correct answer is d.
If they are to many links then the animals would not have enough food energy
The nutrients from the soil is taken up by the roots
to be distributed to the entire plant. The plant absorbs the nutrients into its
cells and utilized by the leaves, stem, trunk. They are also used to grow
flowers and to bare fruits.
Moreover, the nutrients are divided into two groups;
first the macronutrients which is needed by the plants in large amount such as
nitrogen, phosphorus, potassium, calcium, magnesium and sulfur. Second group is
the micronutrients, needed in tiny amounts that include zinc, copper,
manganese, boron, iron, sodium and cobalt. These two groups are essential for
normal plant growth and development.
