Stimulated by the action of the ions on its receptors, the pump transports them in opposite directions against their concentration gradients. ... The sodium-potassium pump carries out a form of active transport—that is, its pumping of ions against their gradients requires the addition of energy from an outside source.

Answer:
TRUE
Explanation:
The Sauropods were the enormous herbivore dinosaurs that had a long neck and a tail, but the size of their head was relatively small. The fossil remnants of a previously existed unknown sauropod dinosaur species named 'Tataouinea hannibalis' were obtained from the rocks of the southern side of Tunisia.
From the fossil evidence, it was observed that a sizable opening was present in the ischium, which actually opens into a large air chamber. This observation supported the theory that considers the presence of abdominal air sacs in this type pf dinosaur species that are similar to the respiratory system of Aves (birds).
Thus, the Sauropods and Aves are closely related to one another.
Hence, the above statement is TRUE.
It would be substitution because an incorrect base pair is being replaced.... hopefully thats right?
