Answer:
The correct answer is D.
Explanation:
The normal value range of pH is 7,35-7,45.
If the pH es <u>higher than 7,45</u> we say it is alkalosis and if the pH es <u>lower than 7,35</u> we say it is acidosis. That being said, we can now rule out option B and C.
Then we have to define <u>respiratory acidosis:</u> it is a decrease of pH because of a high value of PaCO2 (in this case as a result of hypoventilation). The normal range of PaCO2 is 35-45 mmHg.
So if we take all this in consideration, the only option with a low pH and a high paCO2 is option D.
Answer:
(D) sensitive chemical tests and analytical instruments
Explanation:
Toxicology is defined as a science that aims to study the harmful effects arising from chemicals in the body of living beings.
Early toxicologists had archaic chemical tests devoid of any kind of technology, and did not have analytical instruments, or did not have adequate analytical instruments so that they could properly analyze and test the effects of the chemicals. This lack of sensitive equipment and testing has made it difficult to research toxicology in ancient times, but over time, these elements have adapted and met the criteria needed to make toxicology the science we know today.
Health, population and environment education is introduced as an integrated subject due to profound interrelationship that exists among the subject matters of these three disciplines. The natural physical aspects and man- made things come under the physical aspect.
