Answer: they can last 15-20 years if they die of natural causes
Cells were first identified by Robert Hooke in 1665 when he observed the box-like structures in cork tissue under a microscope. In the 1670s, Antoine van Leeuwenhoek became the first to observe living cells. Both their work was instrumental to the understanding of cells and cell theory.
In 1665, experimental scientist Robert Hooke was the first to identify cells. He used the term 'cell' to describe the box-like structures he observed in a cork tissue using a lens, as documented in his publication Micrographic. Hooke's concept of a cell was based on his microscopic observation of the dead cork tissue. He likened the tiny subdivisions in the cork to the small rooms, or cells, that monks resided in.
Antoine van Leeuwenhoek, in the 1670s, became the first person to observe living cells, specifically bacteria and protozoa. Advances in lenses, microscope construction, and staining techniques throughout the years enabled the viewing of components within cells, further refining our understanding of cell structure and function.

Answer:
A) Nerve and muscle cells use more energy
Explanation:
Mitochondria are located near sites of high ATP utilization such as in muscle cells and neurons.
In the cells of the heart muscle these mitochondria are located near the contractile apparatus, which is where the hydrolysis of the ATP is carried out to generate the necessary energy in the contraction. In musculoskeletal cells the number of mitochondria is increased between 5 and 10 times when the muscle is exposed to continuous contraction.
In the neuronal cells there is a high workload suffered by the cell and a high energy expenditure
