Why are we living longer now? Well during the Industrial revolution we made a significant reduction in the amount of deaths by increasing in food production and distribution, improving public health (mainly water and sanitation), and as for medical technology, we made vaccines and antibiotics. Modern medicine prospers every day, being able to cure almost any disease. Because of all of this we gradually started living longer. Back in 1950, life expectancy was 68.2 years old. Nowadays, that
number has risen to 79.12 years old and is expected to increase up to
83.9 years old by the year 2050.
C is the correct anwser because it proves how we are very dependent on chemicals.
meteorologist most likely research on atmospheric conditions
<u>Explanation:</u>
A meteorologist are scientist who study about weather i.e., who uses scientific principle to understand and forecast the earth’s atmospheric conditions. There are many specialised areas that a meteorologist works on like air pollution meteorology, global climate model and numerical analysis and forecasting.
Some of the sectors that meteorologists are often found working in are government agencies, industrial organizations, radio and television stations and in the education sectors. Some of the devices that are used to study weather conditions are thermometer to measure temperature, barometer to measure the pressure variable, anemometer to measure wind, and hygrometer for measuring humidity.
Answer:
There are 3 unique triangles that can be drawn with interior angles measuring 40º, 40º and 100º.
Explanation:
We should remember that according to Euclidean geometry the sum of internal angles in every triangle equals 180º and that every angle is opposed by a side. Given the values of internal triangles, the possible combinations are described below:
,
