Answer:
La escala temporal geológica, escala de tiempo geológico o tabla cronoestratigráfica internacional es el marco de referencia para representar los eventos de la historia de la Tierra y de la vida ordenados cronológicamente. Establece divisiones y subdivisiones de las rocas según su edad relativa y del tiempo absoluto transcurrido desde la formación de la Tierra hasta la actualidad, en una doble dimensión: estratigráfica (superposición de rocas) y cronológica (transcurso del tiempo). Estas divisiones están basadas principalmente en los cambios faunísticos observables en el registro fósil y han podido ser datadas con cierta precisión por métodos radiométricos. La escala compila y unifica los resultados del trabajo sobre geología histórica realizado durante varios siglos por naturalistas, geólogos, paleontólogos y otros muchos especialistas. Desde 1974 la elaboración formal de la escala se realiza por la Comisión Internacional de Estratigrafía de la Unión Internacional de Ciencias Geológicas y los cambios, tras algunos años de estudios y deliberaciones por subcomisiones específicas, han de ser ratificados en congresos mundiales.2

Answer:
Answer: D
GDP per capita is a measure of a country's economic output that accounts for its number of people.
The unemployment rate is defined as the percentage of unemployed workers in the total labor force.
The infant mortality rate is the number of deaths under one year of age.
Given the above information, a country with a higher GDP would have a more stable economy aiding in growth. A lower unemployment rate would show a surplus of jobs indicating, once again, a steady and growing economy. Lastly, a lower infant mortality rate would show access to advanced medicine and a highly trained medical field. All three of these examples are indicators of a highly developed country.

Answer:
C.) Used cars can have lower initial cost
Explanation:
It's not a risk, as this is actually a benefit.

Answer:
The rise and fall of ocean tides
Explanation:
Food that has been prepared or handled should never be placed on the sales floor before it has been properly chilled to ensure the internal temperature is 10° (51°F) or less. It is important to avoid contamination.
It is important to have into account that the higher the temperatures; the faster food will decompose.
Pathogenic microorganisms (such as fungi and bacteria) can reproduce and grow at temperatures as low as 40°F.
The foods may deteriorate even in absence of noticeable modifications in odor, appearance and/or taste.
