20 questions
Question 1: For a reliable result in the mark recapture method, it is crucial that the marking applied to individuals affects their movement or behavior to ensure they are easily identified during recapture.
A. Ano
B. Ne
Explanation: For a reliable result in the mark recapture method, the marking must not damage the individual or affect its movement or behavior. This precaution ensures the animals behave naturally after marking.
Question 2: Random sampling is primarily important in the quadrat method because organisms are typically uniformly distributed throughout an area.
A. Ano
B. Ne
Explanation: Random sampling is important because the distribution of organisms may not be uniform throughout an area. Placing quadrats randomly across the whole area ensures a true reflection of the distribution.
Question 3: For a reliable result when using population sampling methods, sampling must be repeated to calculate a population average.
A. Ano
B. Ne
Explanation: To achieve a reliable result in population sampling, the sampling process must be repeated to calculate an population average.
Question 4: Immigration and emigration are permissible for reliable results when using population sampling methods, particularly the mark-recapture method.
A. Ano
B. Ne
Explanation: For reliable results, especially with the mark-recapture method, it is crucial that no immigration and emigration occurs. The population must be a closed system to ensure accuracy.
Question 5: The formula P=M x C / R accurately represents the estimated population size in the mark recapture method, where P is estimated population size, M is total number of marked animals, C is total number of animals caught in the second sample, and R is total number of marked animals in the second sample.
A. Ano
B. Ne
Explanation: The study materials explicitly state the mark recapture method formula as P=M x C / R, defining P as estimated population size, M as total number of marked animals, C as total number of animals caught in the second sample, and R as total number of marked animals in the second sample.
