When a clam sperm contacts a clam egg, it triggers ionic changes that result in the breakdown of the egg nuclear envelope, condensation of chromosomes and initiation of meiosis. Two observations confirm that ionic changes initiate these cellular events:  suspending clam eggs in seawater containing 60 mM KCl triggers the same intracellular changes as do sperm suspending eggs in artificial seawater lacking calcium prevents activation by 60mM KCl. The intracellular K+ concentration is 344mM and that of normal seawater is 9 mM.   Why does 60mM KCl affect the changes mimicking the sperm cell? please explain. What does the lack of activation by 60mM KCl in calcium-free seawater suggest about the mechanism of KCl activation? please explain the mechanism.

Physical and Chemical features

The physical property of a compound could be determined without modifying the originality of the compound. Examples of physical properties are density, hardness, color, boiling, and melting point. The chemical property expresses the ability of a compound to undergo a particular chemical change.
