The more the alliances the easier it would be to win the war. This is especially true when the enemy(s) don't know about it. This means that they would be off guard and not aware of the situation, so they will most likely lose the battle.
Third parties generally serve only to take votes from one of the main parties. Third parties generally serve only to take votes from one of the main parties. If the third party has a candidate promising similar things to the Rep. candidate, the Democrats are more likely to win simply because their votes are not being siphoned off. Think of it this way: if a school class were to vote on favorite colors and there were only blue and red to choose from, it would probably be mostly equal. But if the same class were to vote for blue, teal, and red, I would be willing to bet that red would win just because its votes weren't being split like the blue votes were. Teal is the third party. It won't ever win on its own, but it can be influential in that it can help the opposite party win.
Answer:
The correct statment would be: "the hormons of the endocrine system exert their action by lock and key mechanism."
Explanation:
The endoncrine system is responsable of the release of hormons under certain conditions, and in different organs, they go trough the bloodstream. The lock and key mechanism is explained as how the receptors block or release hormonos or instead they don´t. The endocrine system is responsable for the reproductive system, and regulates metabolic processes.
