Answer:
The trans-Amazon highway.
Explanation:
- The highway was launched on the September 27, 1972, is a 4000 km long highway that is the longest highway of the brazil state and this runs through the Amazon rainforest and the Brazilian stats of the Paraíba, the Ceará, the Piaui, Maranhão, the Tocantins, the Pará, and Amazonas, is named as the BR 230.
- <u>Ther highway was integrated into the region with the rest country like the Colombia a the Peru and the Ecuador and this affected the northeastern region of the country and a paved pathway of the </u><u>5200 </u><u>kilometers long. Construction of the highway is a challenge due to the remoteness of the site. And due to the project, many forests have been cut and destroyed. </u>

Explanation:
- Microscopes: Anton van Leeuwenhoek is considered the precursor of cellular and experimental biology as well as microbiology, in 1674, he used a homemade microscope to become the first person to discover microbes, he described seeing animalcules in a drop of water, he also discovered red blood cells and bacteria in 1676.
- Pasteurization: it's a process in which water and certain foods like milk and juice, are treated with mild heat, usually before boiling point, to eliminate pathogens. It was named after Louis Paster, who in the 1860s demonstrated that heating beverages to about 57°C for a few minutes could prevent abnormal fermentation, this treatment also destroys microorganisms that cause spoilage and so it prolongs the storage time of food.
- Koch postulate: In 1890, Robert Koch set out his criteria for judging whether a bacteria is the cause of a disease. These postulates are: The bacteria must be present in every case of the disease, it must be isolated from the host and grow in culture, the disease is reproduced when a bacteria from the pure culture is inoculated into a healthy host, the bacteria must be recoverable from the infected host. These postulates are useful to find the cause-effect relationship between bacteria and clinical disease.
- Antibiotics: In 1928, Alexander Fleming, discovered mold as an antibacterial agent after this one contaminated his<em> Staphylococcus aureus </em>dishes, inhibiting it's growing, this mold was then named penicillin and it was the beginning of a transformation in human health.
- Vaccines: the first successful vaccine development was introduced in 1796 by Edward Jenner, this advance was achieved after he followed up his observation of milkmaid who previously caught cowpox did not later catch smallpox by showing that inoculated cowpox protected against inoculated smallpox.

Answer:
The pyroclastic surge would take 1.609 minutes to reach the site of ancient Pompeii.
Explanation:
The ruins of Pompeii are about 5 miles away from Mount Vesuvius. A mile equals to 1.609 kilometers. If pyroclastic surge travels in a straight line at constant speed, then the time (
), in minutes, taken to reach the site of the ancient Pompeii can be determined by the following kinematic equation:
(1)
Where:
- Travelled distance, in kilometers.
- Speed of pyroclastic surge, in kilometers per hour.
If we know that 
and 
, then the time needed to reach the site of ancient Pompeii is:
The pyroclastic surge would take 1.609 minutes to reach the site of ancient Pompeii.
