Wind observations are measured in two ways .... wind speed and wind direction. Where possible measuring devices should be in a large open area away from possible interference such as building, trees etc.
Electron transport system. Definition. noun. A sequence of redox reactions wherein the transfer of electrons from an electron donor to an electron acceptor is coupled with the transport of protons across a membrane to generate a proton gradient that drives ATP synthesis.
Active transport. Definition. noun. A kind of transport wherein ions or molecules move against a concentration gradient, which means movement in the direction opposite that of diffusion â or â movement from an area of lower concentration to an area of higher concentration.he movement of a substance across a membrane from a region of its lower concentration to a region of its higher concentration against a concentration gradient, using energy. This energy is supplied through respiration using ATP. Mitochondria (cell organelles in the cytoplasm) control energy release.
