B) environments in which they were raised were different enough to affect the expression of their genes.
C) one twin received genes only from the mother while the other twin received genes only from the father.
D) environments in which they were raised were different enough to change the genetic makeup of both individuals.

the correct answer is b

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint

the limb fractures are among the most common fractures. open fractures are comparatively more dangerous. the injury patterns are dependent on many factors, such as the age of the person, and mechanism of the injury. the closed fractures of the limbs if left untreated may lead to a significant amount of the blood loss, which may be life-threatening for the person. approximately 1000-1500 ml of blood is lost in the close fracture of the femur, and 500-1000 ml of blood is lost in the closed fracture of lower part of the limbs.

increases the risk of extinction
