- Miss l is bored in the summer, so she wants to estimate the population of weeds on her property. The property measures 20 m x 20 m. She randomly places ten 1 m x 1 m quadrats on her property as shown in the diagram below. What is the estimated population size?When the average mass of individual plants in a stand is plotted against stand density (log-transformed), the slope of the relationship is very often around Multiple Choice -1/2. -1. +1/2. -3/2. +3/2.Using the attached image and chart, calculate the doubling time for a population with the given growth curve. Coordinates are presented as (time, Ln(population).

- Draw a Lineweaver-Burk plot for these data. Put both sets of data on the one graph, use a different symbol of each plot and indicate which set of data is which. Add a line of best fit (trend line) for each set of data. Indicate the values of the Y-intercept(s) and the X-intercept(s). Make sure your graph has appropriate axis labels and units.Measure the migration of each band in the marker lane from the well. Using a semi-log scale, plot this migration distance (×-axis) versus the size of each marker band (y-axis). Generate a standard curve.The grassland ecosystem of Montana is being studied for its resilience as the population of its keystone species, the prairie dog, has declined in recent years. Four plots are established, two that still contain populations of prairie dogs and two that no longer have prairie dogs due to outbreaks of plague. A survey is done measuring the total number of producers (number of plants) and the diversity of producers (number of species) of each plot. The data are summarized in the table. Based on this data, which of the following correctly describes how the total number of plant and plant species will change over time in these plots? A - Plots 2 and 3 will show equal decline in plant and plant species due to the lack of a keystone species. B - Plots 1 and 4 will show a decline in plant and plant species due to an increase in the number of prairie dogs consuming the producers. C - Plots 2 and 3 will show a decline in plant and plant species, but plot 3 will show a slower decline due to a…

Then, state if it is a density-independent limiting factor or a density-dependent limiting factor. Then, state the specific limiting factor that is occurring. The first one is done for you as an example. SITUATION Dependent - Independent or Density-Dependent Limiting Factor Mrs. Engelbrecht has 32 students assigned to her Biology Class, but she only has room for 28. Because the room is crowded, the extra 4 students leave room to go to Guidance and have their schedules changed. Density- Dependent Emigration Northern pike (it’s a fish) feed on another fish, the yellow perch. An increase in the yellow perch population causes an increase in the northern pike population.
