D. It's harder body parts. A lot of fossils are of the skull, therefore that would lead one to think that it would be harder<span />
It changes because the age increases
They are all not plate tectonics
<span>The answer is:
Photosynthesis: 6 CO</span>₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
Respiration: C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + ATP<span>
Cellular respiration and photosynthesis are
complement reactions to each other. These are reverse reactions. In
cellular respiration glucose (</span>C₆H₁₂O₆) and oxygen (O₂) yield carbon dioxide (CO₂) and water (H₂O) and energy is released in the form of ATP. In the opposite
reaction - in photosynthesis, carbon dioxide (CO₂) and water (H₂O) yield glucose (C₆H₁₂O₆) and
oxygen (<span>O₂)</span><span>. </span>
