The answer is diploid. Diploid cell is a cell that contain two copies of each chromosomes. Nearly all the cells in the human body carry two homologous or similar copies of each chromosome. However the cells in the germ line, which produce gametes, or egg and sperm cells are haploid. Haploid cells contain contain a single set of chromosomes. In diploid cells one set of chromosomes is inherited from the mother, while the other is inherited from the father.
I think the answer would be because if there is an error in the DNA replication, it would affect one generation of cells. if the error would fall in the transcription or translation, there would only be one cell affected.
Both primary (herbivores) and secondary (carnivores and omnivores) consumers are heterotrophs, while primary producers are autotrophs. A third type of heterotrophic consumer is a detritivore. These organisms obtain food by feeding on the remains of plants and animals as well as fecal matter.
