18. The graph below shows a model of population changes over time in a predator and its prey. Prey Population Size Predator Population Size Predator Which of the following data would be most helpful in predicting possible disruptions to the relationship between the predator and its prey? (A) Time of day, because a day become shorter time hunting increases (B) Average birth weight of predators, because heavier offspring will begin hunting at younger ages (C) Numbers of additional predator species, because additional predators will increase competition for peey (D) Prey metabolic rates, because predators are less accessful against prey with higher metabolic rates 84 The annual rainfall in the Amazonbasin watershed is several times greater than the amount of water that flows out of the Amazon into the Atlantic Ocean. The most likely reason for this observation is (A) seasonal rainfall (B) annual fluctuations of rivers (C) loss to underground drainage (D) vegetational evapotranspiration (E) sequestration of water in the forest biomass 22. An experimenter who incorrectly rejects the null hypothesis commits which of the following kinds of error (A) A systematic error (B) A random error (C) A Type I crror (D) A false alarm E The fundamental attribution error 48. Both C4 and CAM plants employ physiological and hicchemical strategies to reduce photoespiration. Which of the following is an accurate comparison of the two strategies? (A) C4 plants fix Co, as the 4-carbon acid oxaloacetate, while CAM plants fix CO, the carbon acid ribulosel. 5 bisphosphate (B) C#plants fix Co, in the mesophyll but carry out the Calvin cycle in the bundle sheath. while CAM plants fix Co, and carry out the Calvin cycle in the mesophyll C) C4 plants fix Co, in the bundle sheath but carry out the Calvin cycle in the mesophyll while CAM plants fix Co, and carry out the Calvin cycle in the bundle sheath (D) C4 plants store Co, as phosphoglycolate, while CAM plants store CO, as cloacetate E) C4 plants carry out photosynthetic electron transport in the daytime, while CAM plants carry out photosynthetic electron transport at night.

Answer 1

Sol. 22

An experimenter who incorrectly rejects the null hypothesis commits an error known as "a type I error".

A type I error occurs when a researcher incorrectly rejects a true null hypothesis. This means that your report that your findings are significant when in fact they have occurred by chance.

A type I error is also known as a false positive.

So, option (C) is the correct answer for this question.
