The mid piece of sperm contains mitochondria, which is required for energy production. The energy is used to propel the flagellum(tail).

Oxygen and glucose are the raw materials. Enzymes guides the process
The changes only are passed down when they are in the gametes... So the answer is sex cell
Mitochondria must be present in order for aerobic respiration to occur
No, sperm are small packets of genetic material designed to fertilize an oocyte in the female reproductive tract. In fact, the sperm have just enough resources to get to the oocyte - the oocyte must supply much of the energy and resources necessary to complete fertilization. However, if a female were to ingest sperm, the female's digestive tract would break the sperm down into component amino acids which would provide minimal nutrients to the female.

The four factors of production (land, labor, capital and entrepreneur) must all present if you wish to improve the economic level of production.
The mutation must be present in the Reproductive cell, Ovum/Egg in females (present in the Ovary) and Sperm in males.
Male sperm determine the sex of the baby, not chemicals, etc.
Air pollution, overpopulation, energy consumption, waste production, deforestation, waste production,
Um....no. There must be an egg present for the sperm to fertalize. The DNA in each the sperm and the egg "compliment" each other so they can recombine and form a complete set of chromosomes. Without that, or if there's an error somewhere in the process, the zygote would not be viable and would die anyway.
environmental impact, energy production costs, AND benefits of the new production method
In terms of electricity production, home heating, and industrial processes, natural gas must be the most vital at present. Obviously oil is most important for transport. Coal is still quite significant for electricity production, as is nuclear power, which is set to increase over the next 10-20 years.
The energy currency for the work that animals must do is the energy rich molecule ATP. The ATP is produced in the mitochondria using energy stored in food.
Amino acids Water Energy must be present.
