Both insulin and glucagon are peptide hormones that target liver cells. the response of the target cells to each of these two hormones is opposite. this information implies that a) the two hormones bind to different cell surface receptors. b) one hormone binds to a receptor on the cell membrane and the other to an intracellular receptor. c) each of the two hormones uses a different second messenger. d) both hormones interact with receptors at the cell nucleus. e) the two hormones bind to different receptors and use a different second messenger

looks like the answer is     c     to me!

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.
