capability of local jurisdiction?
A Foreign government
B. Private Sector
C. Federal government
D. State government

Answers

Hey,

Answer:

When an incident grows beyond the capability of a local jurisdiction, and responders cannot meet the needs with mutual aid and assistance resources, the next step is usually a request for: Activation of the state/territorial emergency operations center. The JFO uses an ICS structure to direct on-scene operations.

The next level of government that responds to an incident that is beyond the local jurisdiction is : ( D ) State government

When an incident occurs the first responders are usually the local jurisdiction with the use of mutual aid, but as the incident expands or has the tendency to expand beyond the capability of local jurisdiction, the next level of government in the hierarchy that will respond to the incident is the state government

Tumors developing in epithelial tissue are known as carcinomas, these tissues cover the exterior of the body, such as the skin. The majority of malignancies are also most frequently developed in epithelial tissue.

All malignancies in humans are carcinomas, which develop from epithelial tissue. Breast and colonic epithelium are home to two of the most prevalent malignancies in humans.
