A gardening company would like to predict the density of the weed population in a yard before it is sprayed with pesticide. The yard measures 200 cm × 100 cm. The gardener  places four 2.0 cm × 1.0 cm quadrats randomly in the park, and calculates the weed counts of 22, 46, 32 and 40 weeds in the 4 quadrats. Solve for the density of the weed population.

‏There are two pots of honey (2 patches of habitat). In one pot there is 3 pounds of honey, and in the other there is 7 pounds of honey. A total of 20 bees arrive to eat honey. How many should reed from the pot with 7 pounds of honey if the bees select pots to feed from according to an "ideal free distribution"?

Can someone please let me know what this map is depicting? This is not a graded question. I am simply doing research on migratory patterns of roe deer and I am confused about this. What are the upper range figures depicting? Why is there a spread between the weeks? I just need help understanding the altitudinal gradient.

Jenny wanted to know whether the type of fertilizer she used affected how well her tomato plants grew. She wanted to test 3 fertilizers: Fertilizer A, B, and C. Jenny split up her garden into 3 sections and planted the same number of tomato plants in each section. When planted, all of the plants were the same height and all sections of the garden received the same amount of sunlight each day. Jenny used Fertilizer A in section 1 of the garden, Fertilizer B in section 2, and Fertilizer C in section 3 of the garden, ensuring that she used the same amount of fertilizer on each plant in each section of her garden. She watered the plants at the same time of day with the same amount of water for 3 months and then she measured how tall each of the plants in each section were. Which of the following is a confounding variable that could affect the results of the experiment if it is not controlled? Choose all that apply. Type of fertilizer |Amount of sun exposure Amount of fertilizer Watering

I am testing the prediction that locations with a higher abundance of seeds will have more ant species coexisting there. I am studying many different locations with many different values of seed abundance. What kind of statistical test would be best for testing my prediction? Chi-square ANOVA Regression

A scientist is studying the effect a new fertilizer has on the root growth of bean seedlings. Three groups of plants are grown in the same location in a greenhouse, each receiving the same amount of sunlight and water every day. The scientist measures the length of the roots for each plant every day. The scientist then calculates the mean for each group for five days. The results are shown in the following table. Fertilizer Experiment Data Table A What is the independent variable in this experiment? B с Day 1 Day 2 Day 3 Day 4 Day 5 D Group 1 0 mg 3.0 cm 3.2 cm 3.4 cm 3.7 cm 4.2 cm the amount of water given to each plant the amount of fertilizer given to each plant Group 2 5 mg 2.7 cm 3.1 cm 3.7 cm 4.2 cm 4.6 cm the place in the greenhouse where each plant was placed the type of soil used for each plant Group 3 10 mg 2.9 cm 3.3 cm 3.7 cm 3.9 cm 4.1 cm

Zebra mussels are an aquatic invasive species that are threatening the diversity and abundance of native species in the lake ecosystems of Alberta.    Sylvan Lake is a beautiful recreational lake located in central Alberta. It has a total area of 43 km2.    If the population of zebra mussels is estimated to be 128 mussels/200 km2, calculate the size of the zebra mussel population in Sylvan Lake.    Express your answer as a value rounded to one decimal place.  Answer

Intraspecific competition is a competition between members of the same species and is commonly observed in crop plants. Table 6.2 shows the results of a greenhouse experiment which examined the effects of density on the germination and growth of barley. Plants were grown for two weeks in 10- cm diameter pots kept in identical environmental conditions and watered regularly. At the end of the experiment the plants were cropped by cutting the stems at the soil surface. Based from the given table and graph, discuss the data and  the relationship of the two factors (Mean wet biomass of plants (g) and  Number of plants that germinated). Then, what is the effect of density to the Mean wet biomass of plants?

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.
