In the respiration-photosynthesis cycle shown above, what are the reactants of cellular respiration that belong in box 1?
a.
glucose and oxygen
b.
atp and methane
c.
protein and nucleic acids
d.
carbon dioxide and water

The answer is actually D. glucose and oxygen.

Explanation: The processes of photosynthesis and cellular respiration are interdependent. The products of one process act as the starting materials, or reactants, of the other process.

Photosynthesis produces glucose and oxygen. These products are used as reactants in the process of aerobic respiration. Aerobic respiration produces carbon dioxide and water. These products are used as reactants in the process of photosynthesis.

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
