Answer:
atoms determine the number of valence electrons determine the stability of the atom based on reading the topography of the atmosphere
Answer:
Synovial membrane
Explanation:
The joint cavity is filled with synovial fluid, secreted by the synovial membrane (synovium) which lines the inside of the articular capsule. The synovial fluid is the fluid that lubricate the lining of joints and the sheaths of the tendons.
Answer:
B
Explanation:
Gas exchange provides oxygen that is required for aerobic cellular respiration. Aerobic respiration produces more ATP molecules than anaerobic respiration. This is because oxygen acts as the ultimate proton acceptor (in the Krebs/Citric cycle) in the matrix of the mitochondria to form water as the waste product. This allows a proton motive force to be created in the mitochondria that is harnessed by ATP synthase to produce ATP molecules.
