Based on the passage, which of the following best describes the greenhouse effect?

The constant presence of diseases or infectious agents within a given geographic area or population group. it may also refer to the usual prevalence of a given disease with such area or group. it includes holoendemic and hyperendemic diseases. a holoendemic disease is one for which a high prevalent level of infection begins early in life and affects most of the child population, leading to a state of equilibrium such that the adult population shows evidence of the disease much less commonly than do children (malaria in many communities is a holoendemic disease). a hyperendemic disease is one that is constantly present at a high incidence and/or prevalence rate and affects all groups equally. so probably family history.

Hey the answer is the politics of the southern united states generally refers to the political landscape of the southern united states. due to the region's unique cultural and historical heritage, including slavery, the south has been involved in many political issues. some of these issues include states' rights, reconstruction, the civil rights movement and social conservatism. from the 1870s to the 1960s, the region was referred to as the solid south, due to their consistent support for democrats in all elective offices. as a result, its congressmen gained seniority across many terms, thus enabling them to control many congressional committees. in presidential politics, the south began to move away from national democratic loyalties with the dixiecrat movement of 1948 and the barry goldwater presidential campaign of 1964. among white southerners, democratic loyalties first fell away at the presidential level, followed much later at the state and local levels.
