compare and contrast the processes of photosynthesis and aerobic respiration. how are they similar and how do they differ?
Brut [27]

Answer:

Explanation:

Photosynthesis and cellular respiration (aerobic) are both metabolic processes that occur in specialized organnelles of living cells. These two processes are so unique to one another in the sense that one uses the product of the other as a reactant and vice versa.

Photosynthesis is an anabolic reaction that occurs in the Chloroplast of autotrophs in which captured energy from sun is used to synthesize organic food (glucose) by combining carbondioxide (CO2) and water. Oxygen is released in this photosynthetic process.

6CO2 + 6H20 --------> C6H12O6 + 6O2

Aerobic cellular respiration, on the other hand, is a catabolic process undergone by every aerobic living cell (in the mitochondria) in which glucose is broken down in the presence of oxygen to produce ATP (energy) releasing CO2 and water (H2O) in the process.

C6H12O6 + 6O2 ------> 6C02 + 6H2O

One spectacular difference is that photosynthesis uses solar energy (from sun) while aerobic cellular respiration uses chemical energy to power the process.

Which planet appears to be rotating on its side
katrin2010 [14]

Answer:

Uranus

Explanation:

A new study finds that the same impact that knocked Uranus sideways may have also created the planet's moons. ... However, Uranus is an oddball in that its axis of spin is tilted by a whopping 98 degrees (relative to the plane of the solar system), meaning it essentially spins on its side.
