Question is which is NOT a good technique.
Answer is "B" and here's why:
A) Clear questions -- good. People understanding the question will answer accurately.
C) Large sample size -- good. Answers will be more accurate with more people asked (like if you flip a coin 1,000 times its going to be closer to 50% heads than if you only flipped it twice)
D) Random sample -- good. Avoids your own bias in choosing who to ask.
B) Push poll -- bad. Pretends to be unbiased, the pollster's real objective is to get a person thinking in a way that is to their advantage. Some political candidates do this just before elections.
The correct answer is option B. Higher levels of haemoglobin
A higher level of the haemoglobin allows the organism to survive in low oxygen condition. The low oxygen level decreases the amount of oxygen delivered to the cells, to cope up this condition, there is an increase in the haemoglobin content. The increased haemoglobin concentration allows the delivery of the sufficient amount of oxygen, as the number of haemoglobin increase, the capacity of oxygen carried to the cell is increased.
This disease is classified as a latent disease.
<h3>Classification of diseases</h3>
Latent disease is a classification of disease whereby the infectious agent remains inert in the body of its host between episodes of recurrent diseases.
Examples of viral pathogens that causes latent diseases include:
- <em>Herpes simplex, </em>
- <em>Varicella zoster, </em>
- <em>Human cytomegalovirus, </em>
- Adenovirus, and Kaposi's sarcoma.
The infection caused by the listed viral pathogens exhibit a latent disease phase whereby there is no noticeable symptoms of infection.
