Everyone’s blood falls into one of four groups, or types: A, B, AB, or O.
The type of blood depends on the presence, or absence, of certain substances on red the blood cells. Blood types are inherited.
In blood transfusions, the people giving and those receiving the blood must belong to the same blood type (blood group), or a dangerous reaction will take place from the agglutination that occurs when blood of a different group is present.
One exception is that group 0 Rhesus-negative blood can be used in an emergency for anyone.
A somewhat old-fashioned term used to classify the human shape into three primary types: ectomorphic (a lean, only slightly muscular body with long limbs), mesomorphic (a robust muscular body-build characterized by predominance of structures; including bone and muscle and connective tissue; with pronounced muscular development and low body fat), or endomorphic (characterized by big bones, round face, large trunk and thighs and a naturally high degree of body fat; especially, around the midsection).
One of the four basic bone shapes in the human skeleton; including: long bones, short bones, flat bones, and irregular bones.
Long bones have a tubular shaft and articular surface at each end and refer to the arms (humerus, radius, and ulna) and the legs (the femur, tibia, and fibula) are all long bones.
- Short bones also have a tubular shaft and articular surfaces at each end; however, they are much smaller and include all of the metacarpals and phalanges in the hands, the metatarsals and phalanges in the feet, and the clavicle (collarbone).
- Flat bones are thin and have broad surfaces includeing the scapula (wingbone), the ribs, and the sternum (breastbone).
- Irregular bones are irregular in size and shape and are usually quite compact; for example, the bones in the vertebral column, the carpal bones in the hands, tarsal bones in the feet, and the patella (kneecap).
Boolean (boolean) data type
In computer science is sometimes called the logical data-type, and is a primitive data-type having one of two values: "true" and "false".

2. A sheet printed in colors by any process; such as, a chromolithograph (a colored picture produced by making and superimposing multiple lithographs, each of which adds a different color).
1. An organism that has adapted to its local environment through minor, genetically induced changes in its physiology; yet can still reproduce with other members of its species from other areas that have not undergone these changes.
2. A locally adapted population of a species with limited tolerance to changes in environmental factors.
A positive photograph made directly on an iron plate varnished with a thin sensitized film.
1. The sum total of the genetic information contained in an organism.
2. The genetic constitution of a cell or organism
A genotypic population (group of organisms that share a similar genetic makeup) that is isolated by physiographic barriers (physical features of the earth's surface).
hermetic seal (s) (noun)
, hermetic seals (pl)
A device that is used to close something so it can not be penetrated by air or fluids: The engineer put a hermetic seal on the container so no air could get into it.
