Answer: b. The elderly have a higher risk from toxic pesticides because they are less able to eliminate environmental toxins.
Explanation:
The older adults are expected to have health problems after a pesticide exposure. This is because of the fact that their metabolism is slow and the liver and kidneys are not able to remove the pesticides from the body. The liver and kidney may get injured during the exposure of the high doses of pesticides.
The longer a pesticide stay in the body of an old person this may result in more severe injury. As the body is slow in metabolism that is the conversion of the chemicals in the pesticides into less toxic metabolites. Thus the elderly people will not be able to eliminate the toxin from the body. The toxin will damage the vital organs and can lead to death.
Answer: Option A "Loss of body fluids"
Explanation:
When the body lose blood or other fluids from the body, then the amount of blood in the body is reduced. The Hypovolemic shock happens when a sudden loss of body fluids takes place which is extremely dangerous.
Example:
At the time of delivery, there is blood loss from the body. At the time of injury there is a loss of blood from the body. These processes leads to loss of blood and body fluids.
In case of extensive burns leads to loss of body fluids.
Hence, the correct answer is option A.
Answer:
An asymptomatic carrier
Explanation:
An asymptomatic carrier (healthy carrier or just carrier) is a person or other organism that has become infected with a pathogen, but that displays no signs or symptoms.
Although unaffected by the pathogen, carriers can transmit it to others or develop symptoms in later stages of the disease. Asymptomatic carriers play a critical role in the transmission of common infectious diseases such as typhoid, C. difficile, influenzas, and HIV. While the mechanism of disease-carrying is still unknown, researchers have made progress towards understanding how certain pathogens can remain dormant in a human for a period of time. A better understanding of asymptomatic disease carriers is crucial to the fields of medicine and public health as they work towards mitigating the spread of common infectious diseases.
