<u>Answer:</u>

<em>The level of carbon dioxide in the now is 386 \ ppm</em>

<u>Explanation:</u>

It is given that carbon dioxide at the beginning of industrial revolution is 280 \ ppm. It then increased by 38%.

\frac {final level-initial level}{initial level} \times 100=38

final \ level = 38/100 \ initial\ level+initial\ level

=\frac{38}{100} \times 280 + 280=386 ppm

<em>Thus the current amount of carbon dioxide is 386.4  \ ppm.</em>

Increasing carbon dioxide level is a growing concern. It is a result of industrialization and urbanization which has serious consequences. Increased level of carbon dioxide accelerates global warming and it increases the temperature of earth.

sertanlavr [38]

Answer:

c. a biopsychosocial approach.

Explanation:

A psychosocial approach is a model of medicine and psychology that studies the cause and evolution of illness, addiction, and disorder considering biological, psychological, and social aspects. It is opposed to the biomedical model, which is centered on disease and restricted to biological factors.

From a biopsychosocial perspective, health and disease are understood as a result not only of the interaction of the biological factors of the individual's organism, but also of the environment in which they live and their social relationships. An example of this can be seen in the question above, where Mark's addiction is explained by the biological and social factors surrounding him.
