The length of time to cook a roasted chicken is determined by its weight, notes Better Homes and Gardens. A 2.5-pound bird can be cooked as quickly as one hour at 375 degrees Fahrenheit, while a 5-pound bird can take as long as two hours at the same temperature.
Type O is the primary blood type among the indigenous populations of the Americas, in-particular within Central and South America populations, with a frequency of nearly 100%. In indigenous North American populations the frequency of type A ranges from 16% to 82%.
Type O+ is the most common blood type, while AB-is the least common. But not all ethnic groups have the same proportion of blood types. For example, Hispanics have a high number of O blood types, while Asians have a high number of B blood types.
