<span>The elements that are found in a high proportion in Earth's crust are oxygen, aluminium, iron, calcium, potassium, sodium, and magnesium. But for your Option, I think it is B) Oxygen and Silicon. This is because Oxygen makes 46.6% while Silicon makes 27.7% of the Earth crust.</span>
The majority of life on Earth depends on two biological processes: photosynthesis and cellular respiration. Both of these processes utilise a number of similar chemicals, including oxygen (O2), carbon dioxide (CO2), water (H2O), glucose (C6H12O6), and adenosine triphosphate, as well as other complex steps (ATP).
<h3>What three aspects of photosynthesis and respiration are similar?</h3>
The trading of gases is a part of both procedures. The cell's organelle, which was once believed to be an endosymbiotic critter, is where both processes take place.
<h3>What are the parallels and differences between photosynthesis and cellular respiration?</h3>
In the environment, photosynthesis and respiration are complementary reactions. Actually, they are the same reactions that happened in reverse.
