Explanation:
the equations for photosynthesis and cellular respiration are exact opposites. The reactants for photosynthesis are the products for respiration.
<u>photosynthesis:</u>
6CO₂ + 6H₂O + ATP (energy) ---> C₆H₁₂O₆ + 6O₂
<u>respiration:</u>
C₆H₁₂O₆ + 6O₂ ---> 6CO₂ + 6H₂O + ATP
Answer:
In biomes the species community undergoes certain changes in evolution and growth in order to reach the climax.
Explanation:
- An alternative stable state is one which suggests the discrete states are sperate by an ecological threshold and in opposition to the ecosystem that is changing and thereby stating that the ecosystem can exist in a variety of alternative state.
- The first species after origin grows develops and then declines. This community of species may be disturbed in middle such as by a fire or flood and forms the secondary community which is more diamine and resistant. The changes are known as seres in biomes.
<span>The formation of the fertilization envelope (slow-block to polyspermy) requires an increase in the availability of </span>calcium ions.
Slow-block to polyspermy is also called cortical reaction. In this reaction, the sperm will be permanently blocked by cortical granules. The release of calcium ion will trigger this reaction.
