Thrips are insects that feed on rose pollen. Scientists noted that the thrips population
increased in the spring and decreased dramatically
during the summer. The researchers hypothesized
that food abundance was the limiting factor for
the population. Which of the following types of
data would be most useful for the scientists to
collect at regular intervals on a designated test
plot of rose plants?
(A) Amount of sunlight (hours/day)
(B) Mean temperature (°C)
(C) Density of rose pollen produced (g/m²)
(D) Amount of pollen produced by each
flower (g/flower)

Which of the following initial observations would more directly lead to this research study? a) ginko biloba is cost effective and also possesses heart-protective, antioxidant, anti-inflammatory properties. b) metformin is an effective treatment of patients with t2d, but shows side effects that complicate the disease state. c) over the past several years, the cost of treating t2d within the united states has increased dramatically. d) many plants contain molecules that improve the health and quality of life of patients with a variety of diseases like t2d. e) t2d affects millions of individuals in the usa and worldwide many of who could benefit from improved therapies.
