Refined carbohydrates are plant-based foods that have the whole grain extracted during processing. The process of refining a food not only removes the fiber, but it also removes much of the food's nutritional value, including B-complex vitamins, healthy oils and fat-soluble vitamins.ike bread, some forms of rice are considered to be refined grains. White rice and most of the quick-cook rices are refined and, as a result, do not contain an intact grain.
The Claim: Identical Twins Have Identical DNA. It is a basic tenet of human biology, taught in grade schools everywhere: Identical twins come from the same fertilized egg and, thus, share identical genetic profiles. But according to new research, though identical twins share very similar genes, identical they are not. The discovery opens a new understanding of why two people who hail from the same embryo can differ in phenotype, as biologists refer to a personâs physical manifestation.
No. In order for them to be identical they needed to start off as the same cell and divide so at first their DNA is identical meaning they have the same sex. During development slight changes may occur but the sex always stays the same. Boy-girl twins are always two different cells meaning that they are not identical. The term for boy-girl twins is furturnal. You can however have boy-boy twins and girl-girl twins that are not identical and they are also called furternal. So basically, identical twins start off as one cell that divides and furternal are two individual cells.
