Each excavation job as in any other case, must be evaluated as to the facts relating to the needs of a competent person, and qualified person. The professional judgement of OSHA must come into play by using our construction regulations where they apply.
Definition: A diploid cell is a cell that contains two sets of chromosomes. One set of chromosomes is donated from each parent. Examples: The diploid number of a cell is the number of chromosomes in the cell. This number is commonly abbreviated as 2n, where n stands for the number of chromosomes. For humans this equation would be 2n=46. Humans have 2 sets of 23 chromosomes for a total of 46 chromosomes:
A cell is diploid if it contains exactly two copies of each chromosome. A cell is haploid if it contains exactly half of a speciesâ typical full set of genetic material. Haploid cells are often used in sexual reproduction. In cells, ploidy defines the number of copies of a chromosome found within the cell. The number of the basic set of chromosomes is described as the monoploid number. Most cells within a human (and other animals) are diploid, which means they have two copies of each chromosome.
