Humans affect the phosphorus cycle mainly by the use of fertilizers and raising livestock, especially hogs. Fertilizers and hog waste are high in phosphorus, which makes its way into the soil (where it is necessary in moderate amounts) and, due to runoff, in water.Apr 27, 2012
Answer:
When you add oxygen to methane to produce carbon dioxide and water, that's also oxidation. The carbon atom loses electrons, and its oxidation state changes while the oxygen atoms gain electrons and are reduced. This is known as a redox reaction
Explanation:
Answer:Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
Explanation: I hope you understand!
Answer:
D because asexual reproduction allows an organism to make a baby anytime, and so you dont need a male and female thus making it easier to make a baby
Explanation:
Motor neurons carry impulses to the effectors in the body, which are the muscles or glands that produce a change based on a stimulus sensed by the receptors. The motor neurons "innervate" muscle fibers, which essentially means that they cause them to move. The fewer the muscle fibers associated with a motor neuron, the more precise are the movements of those fibers. Having to control a small number of fibers, the neuron is able to coordinate more dexterous motions. An example of a region where there are not a lot of muscle fibers related to each neuron is in your fingers.
