Concept explainers
a.
To define: The plot the bead size versus the percentage of beads buried by the dung beetles.
Introduction: Large seed mimics, dispersal was equally low in secondary forest, agriculture and pasture, but was higher in agroforest. This suggests that dispersal of large seeds might suffer even in habitats that maintain a relatively complex vegetation structure.
b.
To describe: The regression line relationship in the graph and predict the percentage of beads of diameter 5mm and 14 mm that would be buried by the beetles.
Introduction: Linear regression is a model to represent the relationship between two variables by fitting a linear equation to observed data.
c.
To describe: The factors other than the size of beads of seed burial by the dung beetle, hypotheses with an experiment.
Introduction: Animals, birds and insect disperse the seeds in a distant place where the seed can germinate providing the suitable conditions.

What would be the protein needs of a man named Josh who exercises moderately and is the same age and size as Wayne? Josh is 5 ft, 8 in tall and weighs 183 lb. Round the number of grams to the nearest whole number. During calculations, use numbers rounded to the first decimal place. Because protein requirement is a range, please enter two numbers: lower and upper range values, respectively. Separate the lower and upper range values, in that order, by a comma. ___, ___ g ?arrow_forwardC MasteringHealth MasteringNu X session.healthandnutrition-mastering.pearson.com/myct/itemView?assignment ProblemID=17396422&attemptNo=1&offset=prevarrow_forwardIf left untreated, most HIV-infected individuals will develop AIDS. Current treatments are focused on highlyactive antiretroviral therapy (HAART). HAART usually consists of an orally delivered drug cocktail containingtwo different reverse transcriptase inhibitors and one other drug, such as a protease inhibitor. Question: Develop a pharmacokinetic model of HAART treatment. Consider all 3 drugs. Make sure to include adiagram that illustrates your thinking, state all assumptions, and define your variables. Whatparameters would you need to know to find the concentration of drug in the plasma? In the T cells?(You do not need to write out or solve any equations.)arrow_forwardnot use ai pleseaarrow_forward(A) 25 20 20 15 NPP (Mg C/ha/yr) 10 10 5 0 0 2,000 4,000 6,000 ECOLOGY 4e, Figure 20.11 (Part 1) 2017 Sinauer Associates, Inc.
