Answer:
The development in the field of genetic engineering allowed the production of insulin in E. coli and yeast, which have been approved for therapeutic applications in human by FDA [14,15]. Nowadays, recombinant human insulin is mainly produced either in E. coli or Saccharomyces cerevisiae.
Answer: E.coli or Escherichia coli
Explanation:
1. Obtain the segment of DNA in a human chromosome that contains insulin gene. Cut the gene using a restriction enzyme. This enzyme cuts the restriction site at the two ends of the gene to produce sticky ends. Each sticky end is a single strand sequence of DNA bases. These bases can pair with complementary bases to form a double strand.
2.Obtain a plasmid from a bacterium. Cut the plasmid with same restriction enzyme. This produces 'sticky ends' complementary to the ends of the Insulin gene.
3. Mix the plasmid with the DNA segment containing the human insulin gene. The human insulin gene will bind to their sticky ends. Add the enzyme DNA ligase to seal the human plasmid containing DNA from two different organisms is recombinant plasmid
4. Mix the recombinant plasmid with E.coli bacterium. Apply temporary electric shock. This opens pores of cell surface membrane of the bacterium for the plasmid to enter.
5.The transgenic bacterium will use the new gene to make insulin
The insulin protein has to be extracted and purified before it can be used
B) Increase logistically.
C) Decrease rapidly and die out.
D) Remain the same.
The toad population would most likely Increase exponentially.
Exponential growth of species is the unrestricted growth of a population of organisms.
Exponential growth occurs in absence of predators and when resources of food in its habitat are unlimited.
Predation and resource availability are two important factors in exponential growthof population.
Thus, when a species of toads is introduced into a new environment in an attempt to reduce the populations of insects, in absence of any natural predators to toad, the toad population would most likely increase exponentially.

Phosphorus is a key component of the energy molecule ATP.
ATP stands for adenosine triphosphate, and it is a molecule that carries energy within cells.
The energy is stored in the phosphate bonds of ATP, and when these bonds are broken, energy is released for cellular processes such as muscle contractions, protein synthesis, and nerve impulses. The phosphorus atom is what makes the phosphate bond in ATP so high in energy, and this is what allows ATP to be such an effective energy carrier within cells.
The phosphate groups are linked by high-energy bonds, and when these bonds are broken, energy is released that can be used for various cellular processes.
The breakdown of ATP into ADP (adenosine diphosphate) and inorganic phosphate releases energy, while the formation of ATP from ADP and phosphate requires energy. The energy stored in ATP is used for various cellular processes such as muscle contraction, protein synthesis, and active transport across cell membranes.
