Since ponds are typically shallower than lakes, this allows more sunlight to reach pond plants than lake plants. By getting my sunlight, these pond plants can photosynthesize more efficiently.
Illness and disease is the answer
Answer:
The second sperm entry is blocked by the fertilized oocyte.
Explanation:
An ovum prevents polyspermy by two mechanism:
1. When the first sperm fuses with the oocyte then rapid depolarization of egg's plasma membrane takes place which prevents other sperms to fuse with the egg.
2. The fusion of sperm cause an increase in the amount of calcium ion in the cytosol of egg. This higher calcium level activates the development of egg which results in the change in the structure of the egg's outer layer. The outer layer(zona pellucida) becomes hard and prevent the entry of other sperms.
So the chromosomes from the 2nd sperm cell will not normally function in the resulting embryo because the fertilized oocyte block the entry of other sperms.
Answer:
Explanation:
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).
