It is also possible to move substances across membranes against their concentration gradient (from areas of low concentration to areas of high concentration). ... If the energy of ATP is directly used to pump molecules against their concentration gradient, the transport is called primary active transport.

Answer: robotic structures will truly give a sense of invincibility to people. Might even perform lab tests without the intervention of humans.There are good reasons for engineers to develop medical robots for use in healthcare. Unlike human beings, robots are tireless, and their "hands" never shake. They can perform precise movements even beyond the human range of motion and be present with patients for as long as necessary. Plus, they can automate lower-level or repetitive tasks and leave the high-level work to humans.

Answer:
Robinson explains how she uses layers in fossilized corals to understand what the environment was like overtime. By finding out what mainly makes up each layer and finding out roughly how old each layer is, she can begin to understand what the chemical composition and climate was like when the coral pieces were alive
