I'm going with C. It may be wrong but I think it's C.
Answer:
The flow of heat from Earth's interior to the surface is estimated at 47±2 terawatts (TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of Earth.
A tropism.
A plant movement to a light stimulus is a phototropism.
A plant movement to water stimuli is a hydrotropism.
etc. etc. :)
The right option is; c. biomes
Savanna is considered a transitional biome because it is intermediate between two biomes.
A savanna is a tropical grassland ecosystem that is characterized by widely spaced scattered trees. Savanna is an extensive plain that is regarded as a transitional biome because it is intermediate between moisture equator forests and tropical deserts. It covers about 20% of the earth’ surface. Savanna has seasonal water availability and during the dry season, there are strong evaporation which makes the trees such as baobab to shed their leaves while bushes and grasses wither.
Answer:
Chemiosmosis
Explanation:
The electrons from from NADH and FADH2 pass through the electron transport chain in the mitochondria, donating their electrons and generating a H+ buildup. This generates a proton pump to power ATP synthase. This process is called chemiosmosis.
