Why was the invasion of the mongols significant and how did it lead to the advancement of the ottomans and safavids?

The invasion of the Mongols lead to the advancement of the Ottomans and Safavids by bringing with them firepower and arms, which made them superior to all enemies.

The Mongol invasion of Europe in the 13th century was a military effort by the Mongols to invade and conquer Europe. It involved the severe and rampant destruction of East Slavic principalities and major cities, such as Kiev and Vladimir. I hope that this was helpful to you. 

hr2520 is the patient's act. there is required the secretary of health to summon a committee to develop a national strategic plan of prevention. this committee has forth provisions that make possible for the govern entities to acquire private health insurance services.

is easier to keep this hr2520 as federal, because that way the secretary of health has centralized power to deal with private insurance companies and the federas government has more ways and power to negotiate with them, than doing this process state by state in their specific terms.
