Spherocytosis is a human blood disorder associated with a defective cytoskeletal protein in the red blood cells (RBCs). What do you suspect is the effect of having a defective cytoskeletal protein in these cells?
a. Abnormally shaped RBCS
b. An insufficient supply of ATP in the RBCs
c. An insufficient supply of oxygen-transporting proteins in the RBCs
d. Adherence of RBCs to blood vessel walls, causing plaque formation

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
