Here are some of the more common reasons your urine's odor may change: 1  Medications or supplements. 2  Certain genetic conditions, such as Maple Syrup Urine Disease, which causes urine to smell sickeningly sweet. 3  Certain foods â most notably asparagus.  Urinary tract infections.
The study of one type of evidence of evolution is called embryology, the study of embryos. An embryo is an unborn (or unhatched) animal or human young in its earliest phases.Embryos of many different kinds of animals: mammals, birds, reptiles, fish, etc. look very similar and it is often difficult to tell them apart. Many traits of one type of animal appear in the embryo of another type of animal.For example, fish embryos and human embryos both have gill slits. In fish they develop into gills, but in humans they disappear before birth.any traits of one type of animal appear in the embryo of another type of animal. For example, fish embryos and human embryos both have gill slits. In fish they develop into gills, but in humans they disappear before birth.
Examples of Analogous Structures. The eye of a human is very similar in structure to the eye of the octopus. In fact, the octopus eye is superior to the human eye in that it does not have a blind spot.Structurally, that is really the only difference between the eyes.nalogous structures do not have to have the same evolutionary path. One analogous structure may have come into existence long ago, while the analogous match on another species may be relatively new.
