Answer:
Despite past improvements in air quality, very large parts of the population in urban areas breathe air that does not meet European standards let alone the health-based World Health Organisation Air Quality Guidelines. Over the last 10 years, there has been a substantial increase in findings that particulate matter (PM) air pollution is not only exerting a greater impact on established health endpoints, but is also associated with a broader number of disease outcomes. Data strongly suggest that effects have no threshold within the studied range of ambient concentrations, can occur at levels close to PM2.5 background concentrations and that they follow a mostly linear concentration–response function. Having firmly established this significant public health problem, there has been an enormous effort to identify what it is in ambient PM that affects health and to understand the underlying biological basis of toxicity by identifying mechanistic pathways—information that in turn will inform policy makers how best to legislate for cleaner air. Another intervention in moving towards a healthier environment depends upon the achieving the right public attitude and behavior by the use of optimal air pollution monitoring, forecasting and reporting that exploits increasingly sophisticated information systems. Improving air quality is a considerable but not an intractable challenge. Translating the correct scientific evidence into bold, realistic and effective policies undisputed has the potential to reduce air pollution so that it no longer poses a damaging and costly toll on public health.

the energy needed to raise the temperature of 1 kilogram of water through 1 °C, equal to one thousand small calories and often used to measure the energy value of foods.
Answer:
What makes the sweat glands in the skin secrete more sweat when the body is hot is the brain signaling the sweat glands to secrete sweat to cool the body.
Explanation:
The sweat produced by the sweat glands is an important mechanism of body thermoregulation.
The perception of the increase in temperature is captured by specific receptors, which send the information to the central nervous system, specifically to the preoptic area, placed near the hypothalamus. Once the information is processed, the brain sends an efferent response to the effector cells, in this case, the secretory cells of the sweat glands.
The<u> body temperature decreases with sweating because evaporation means that the water in the sweat absorbs heat so that this process occurs, which lowers the body temperature</u>.
Answer:
Explanation:
In general, any behavior that does not conform to social norms is deviance; that is behavior that violates significant social norms and is disapproved of by a large number of people as a result. For societies to run with some semblance of order the problem of deviance is essential and intrinsic to any conception of social order.
It is called the Cool down
