Answer:
Mary G. Harris Jones..
Explanation:
She was called Mother Jones because of her effort in trying to protect women..
The rulers of native American, European, African, and Asian empires and kingdoms secured and sustained their power by: (1) they made sure (or at least tried) that only one family must rule, (2) they made sure that their military is strong, (3) They see to it that connections must be made with neighboring powers and if they do not cooperate, they must be destroyed, and (4) they made sure that their subordinates see them as gods.
The ordinary people benefited from these methods of power preservation because all they needed to worry about was food. The disadvantage however is since the seat of power is only given to the ruling elite, they got no say in politics. Plus if the rulers decide their empire or kingdom will go to war, they basically end up being the victims of it.
Answer:
By keeping a thin skeleton, the sand dollar can camouflage itself in the sand.
Explanation:
Sand dollar are very small and peculiar sea urchins. They have very few predators like some fish and starfish, but they manage to get rid of predation with their own bodies, which is very useful for such a small creature. This is because sand dollars have small spines on their bodies, which in addition to allowing them to move forward on the ocean floor with great speed, allows them to hide in the sand, preventing their predators from finding them.
