Which system is not directly connected to itself
Nataliya [291]

Answer:

B) Digestive

Explanation:

The system is dependent in the digestive system because it sends the nutrients to the bones and this helps the bone growth and the repair. It can not be A. since the skeleton system is connected with the muscular system physically, this is to protect muscles and allow the skeletal muscles to make the bones move, so this system is connected with itself with the help of the muscular system! The endocrine is somewhat connected with the nervous system, they are both essential to the communication and response system. This eliminates A and C and leaves you with B!

Ann [662]
₉₂U²³⁵ + ₀n¹ → ₅₄Xe¹⁴⁰ + ₃₈Sr⁹⁴ + 2 ₀n¹
Mass of reactants = 235.04393 + 1.008665 = 236.052595 amu
Mass of products = 139.92144 + 93.91523 + 2* (1.008665) = 235.854000 amu
Mass defect Δ m = 236.052595 - 235.854000 = 0.198 amu
Reaction energy released Q = Δ m * 931.5
                                              = 0.198 * 931.5 = 185 MeV
