Answer: Precipitation
Grasslands are characterized as lands covered by grasses rather than large shrubs or trees. Grasslands are found in regions which receives rainfall that are not enough for the growth of forests. Desert covers about one fifth of the Earth's surface and occur where rainfall is less than 50 cm/year. Rainfall are least frequent in deserts as compared to grassland. The desert-grassland boundaries can change as a result of precipitation. The fate of land form of boundary will be dependent upon precipitation. As, if the boundary receives moderate or sufficient rainfall to grow vegetation then it will be included in the grassland and if the boundary receives no or scanty rainfall then boundary will be included in desert region.
I thibk its a bro but yea im not 100 percent sure
Answer:
The correct answer is option A, that is, cytochrome c oxidase.
Explanation:
A sequence of complexes, which conduct electrons from electron donors to electron acceptors through redox reactions, that is, both oxidation and reduction reactions taking place simultaneously is termed as the electron transport chain. This conduction of electrons is further combined with the mediation of protons across a membrane.
Four membrane-bound complexes are present within the mitochondria, of these in complex IV or cytochrome c oxidase, the withdrawal of 4 electrons takes place from 4 molecules of cytochrome c, and is mediated towards the molecular oxygen, which further gives rise to 2 molecules of water. During the process, 8 H+ are withdrawn from the mitochondrial matrix, which contributes to the proton gradient.
