Answer: cellular respiration reverses the overall photosynthetic reaction, but less efficiently. The useful energy output of respiration is less than the energy input required for photosynthesis.
Explanation:
overall photosynthetic reaction
Light energy + 6CO2 + 6H2O —> C6H12O6 + 6O2
cellular respiration
C6H12O6 + 6O2 —> 6CO2 + 6H2O + energy (as ATP and heat)
Answer: This event is called a genetic mutation
Explanation:
This can be explained when the genetic make up of a species is altered such that a new genetic branch is formed,a information is contained in the DNA leading to a visible change outwardly.
