Biology questions!?

75 Plants can utilize the ?





a) nitrite


b) nitrate


c) N2


d) NO2





80 The great tit is a small bird living in the British Isles. These birds form populations of different sizes, based on the parameters of the habitat they live in. In one particular habitat, the number of great **** has increased by 25% because of some displaced birds from other habitats immigrated. Given this increase in the population size, what population-level change would you expect to occur in the great tit population?





a) The population will crash and slowly recover.


b) Males will create harems with multiple females to increase their fitness.


c) Since the number of nesting pairs has increased, the average clutch size will be reduced during the reproductive season.


d) The greater population density will force some birds to move away during the next season.





85 In public lavatories, when at all possible, males tend to occupy every other urinal. What type of dispersion pattern does this illustrate?





a) random


b) uniform


c) clumped


d) bunched





91 In a certain area of Colorado, some types of shrubs tend to be found only along the stream running through the valley, some are on the side that receives more sun during the day, and others are found primarily on loamy soil deposits. What type of dispersion pattern do these organisms exhibit?





a) random


b) uniform


c) clumped


d) bunched

[uniform dispersion: Even spacing of individuals of the same species within an area.]

[clumped dispersion: Refers to clumps of individuals of the same species scattered throughout the range of that species.]
