In humans, the reduction division results in two sperm cells each with 23 chromosomes or an egg cell with 23 chromosomes and one discarded polar body. The second division or meiosis II is called equational division.
A feedstock is defined as any renewable, biological material that can be used directly as a fuel, or converted to another form of fuel or energy product. Biomass feedstocks are the plant and algal materials used to derive fuels like ethanol, butanol, biodiesel, and other hydrocarbon fuels.
Some feeds are designed to be the primary source of food for the animals, while other feeds are designed to provide animals that eat forage with the extra protein and energy they need to complete their diet, such as sheep and lambs.
