Answer:
Seafloor spreading at the mid-ocean ridge provides the mechanism for tectonic plate movement. The Earth's mantle moves through convection, showing that tectonic plates are able to glide. The location of the plates was determined by locating their boundaries, using data on the Earth's magnetic field.
Answer:
The cytochrome b6f is a large multi-subunit protein, which accepts electrons from the plastohydroquinone.
One electron moves linearly toward plastocyanin while the other goes through a cyclic process, which effectively pumps more protons into the thylakoid lumen.
Explanation:
The cytochrome b6f is distributed among both grana and stroma thylakoids equally. They are usually large and embedded in the membrane.
