For question 2, "Which statement best explains the effect of resources on population size?", let's break down each answer choice to find the correct explanation:
a. the exponential growth curve models the effects of limiting resources on population size: This answer choice suggests that the exponential growth curve is a model that represents the impact of limited resources on population size. It does not directly explain the effect of resources on population size.
b. Limited resources decrease the growth rate of population size: This answer choice accurately explains the effect of limited resources on population size. When resources are limited, it hinders the population's growth rate.
c. Density-dependent factors invariably lead to a positive DN: This answer choice is unclear and does not directly explain the effect of resources on population size.
d. all of the above: This answer choice includes all three previous options. However, only option b accurately explains the effect of resources on population size.
Therefore, the correct answer for question 2 is b. Limited resources decrease the growth rate of population size.
Moving on to question 26, "The relationship between population growth and resources can be described as...":
a. inverse; as one goes up the other goes down: This answer choice suggests an inverse relationship between population growth and resources, meaning that as one increases, the other decreases.
b. parallel; when one goes up, so does the other: This answer choice suggests a parallel relationship between population growth and resources, meaning that when one increases, the other also increases.
c. complex; there are many contributing factors: This answer choice acknowledges that the relationship between population growth and resources is not simple and consists of multiple influencing factors.
d. equal; they both level off in any population: This answer choice suggests an equal relationship between population growth and resources, stating that both stabilizes in any population.
Considering the various factors that may influence population growth and resources, the most accurate answer would be c. complex; there are many contributing factors.
Regarding question 11, "Solar energy can be trapped in the atmosphere by...":
a. the chemical bonds of carbon dioxide: This answer choice suggests that the chemical bonds of carbon dioxide can trap solar energy in the atmosphere.
b. the chemical bonds of ozone: This answer choice suggests that the chemical bonds of ozone can trap solar energy in the atmosphere.
c. radiation: This answer choice is too broad and does not directly explain how solar energy is trapped in the atmosphere.
d. sunlight: This answer choice indicates that sunlight itself can trap solar energy in the atmosphere. However, sunlight is a source of solar energy, not a method of trapping it in the atmosphere.
Considering the composition of Earth's atmosphere, the most appropriate answer would be a. the chemical bonds of carbon dioxide. Carbon dioxide molecules act as greenhouse gases, trapping some of the solar energy in the atmosphere and contributing to the greenhouse effect.
Therefore, for question 11, the correct answer is a. the chemical bonds of carbon dioxide.
