Some cells have more mitochondria because the cells use more energy. The correct option is B.
Mitochondria are the powerhouse of the cell. It is a long cylindrical organelle. Some cells contain more mitochondria than others because they require more energy. The mitochondria store energy for the function of the cell.
So, for example, the muscle contains a lot of mitochondria, as does the liver, the kidney, and, to some extent, the brain, which runs on the energy that those mitochondria make.
Depending on the function of thecell, several mitochondria are frequently found in one cell. Mitochondria, like other organelles, are found in the cytoplasm of cells.
Therefore, the correct option is B. The cells use more energy.

✓ B) The cells use more energy.
Some cells such as human nerve and muscle cells.
40 to 44 percent of people are in the range of 0 to 4 years.
A population is a group of different people. There are three different types of population such as rapid growth, slow growth, and negative growth.
In rapid growth, the population will grow rapidly. While slow growth population grows very slowly. In negative growth population growth is negative.
In the population graph, male and female growth is shown. The darker color in the population shows males and the lighter color shows females population.
Therefore, 40 to 44 percent of people are in the range of 0 to 4 years.

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
