The question is incomplete as it does not have the options which are-
A. naturalistic observation
B. the hindsight bias
C. random sampling
D. the double-blind procedure
E. replication
Answer:
D. the double-blind procedure
Explanation:
The double-blind experiment are the experiments in which both the examiner or researcher and the participant or subject is unaware of that which subject will receive the experimental treatment of the experiment.
The double-blind experiment is performed to ensure that the experimenter is not biased when the subjects have placebo effects.
The test is used to determine the action of the drug on the participants in which the placebo are also used which give the same appearance of the drug but no drug is present in the substance.
Thus, Option-D is the correct answer.
My guess is probably 100 maybe even longer..
Answer:
<em><u>Mode of transmission Method of blocking</u></em>
Indirect Contact -----------→ washing food (A)
Direct Contact -------------→ getting vaccinated (B)
Animal Vector --------------→ using insect repellent (C)
Explanation:
Transmissible infectious diseases are those caused by pathogenic biological agents and can be prevented by preventive measures. Three forms of contagion are direct contact, indirect contact and vector transmission.
<em><u>Direct contact</u></em><em>: occurs with direct exposure to a sick person, their breathing or their secretions. The flu is a disease transmitted by direct contact.</em>
<em><u>Indirect contact</u></em><em>: a sick person contaminates an object or food, which is then handled or consumed by another person, acquiring the disease. Food poisoning or intestinal parasitosis can be transmitted by the consumption of contaminated food by a sick person.</em>
<em><u>Vector transmission</u></em><em>: Some insects, such as mosquitoes, carry diseases that can be transmitted through their bite to a healthy person. Dengue fever is vector-borne.</em>
The preventive measures or to block the spread of diseases, according to the mechanism of transmission, are:
- <em>Transmission by direct contact can be prevented or blocked by </em><em>immunization or vaccination</em><em>.</em>
- <em>Properly </em><em>washing food</em><em> prevents the spread of disease through indirect contact.</em>
- <em>The use of </em><em>insect repellent</em><em> prevents the vector of a disease from spreading it through its bite.</em>
