Using “weights of fish” as an example, explain how data can be collected in both qualitative and quantitative ways. Don’t just give generic definitions of the terms- be specific to this example of weighing fish. Make up data to help teach me!
Step by step
Solved in 2 steps
- Which of the following is an example of qualitative data? 1. The temperature decreased from 20C to 15C. 2. The contents of the stomach are mixed every 20 seconds. 3. The six pairs of robins hatched an average of three chicks each. 4. The fish swam in a zigzag motion.SHOW ALL MATH WORK step by step on paper please!!!!!!! Don't answer the question if you can't follow directions Lotka-Volterra Competition A small lake is capable of supporting both bluegill and smallmouth bass. These two bony fish species compete for similar food resources. The carrying capacity of this lake for bluegill (K) is 1,500 and for bass (K,) is 500. After some careful measurement, we find that a is 0.5 and that pis 0.25. We stock the lake with 250 bluegill and 750 bass. Over time, will both species be able to co-exist? If not, which one will be driven to extinction in this lake? If so, approximately how many of each species will be present?Decribe Brown’s large granivore experiment and what was his hypothesis (Chapter 13)? Why did Brown’s research team create controls by completely fencing study plots and then cutting holes in their sides to allow free passage of rodents into and out of the plot? Why not just compare the density of small rodents in the large granivore removal plots with their densities in the surrounding desert? Why did they look at insectivores and what did the lack of response in insectivores indicate? Why did they repeat their large granivore experiment?
- Use Verbal description of results from graph and then Interpret the graph for Effect of Food Density sccenario in foraging lab. The interpretations must include Were the results expected and Did they support the hypotheses? If so, state the biological significance of the results from graph. If the results deviated significantly from expected results, discuss the hypotheses onthe basis of expected results and include an explanation of why this might be so. Lastly, state the conclusions drawn from the experiment and their biological relevance. Hypothesis: higher food density corresponds to an extended duration of foraging.Thinking Analytically Do you think there are more species of animals on land or in the ocean? What about absolute numbers of animals—are there more animals on land or in the ocean?1) how can you use the data to better understand how the penguins capture prey? You may wish to find the average time it takes the penguin to capture each of the types of prey. You could organize the data into a table. 2) after data, analyze the data as described in question one
- If you adjust each of the four constants, one at a time, by 10%, which seems to have the greatest impact on the simulation output? Examine the Lotka-Volterra equations to explain by this constant makes such a big difference in the predator-prey system. Hint: This constant affects both the birth rate of predators and the death rate of prey.Prey size may favor a particular body size among pumas. Graph the relationship between puma weight and prey weight. Pay attention to which variable is the independent variable.Schmidt-Nielson calculated the swimming cost in a mallard duckand found that it was nearly 20 times as high as the swimmingcost in a salmon of the same body mass. What could explain thegreater swimming efficiency of salmon?
- Great white sharks prefer marine mammals like seals but can eat a number of other prey items, including birds and fish. According to the table below, what is the critical search time for seals, above which great white sharks should choose to eat an albatross if they encounter one? Prey item: seal (energy = 60 Mcals, handling time = 5 minutes) Prey item: albatross (energy = 10 Mcals, handling time = 2 minutes)Feral cat in wild compared to domestic cat are they larger or same size? Feral cats are they tougher then domestic cats for predators like bobcats or raccoons or possum or skunks or weasel? If feral cat has litter how they defend the litter from predators like dogs gain pack to surrive as cats won’t?Figure 2 shows the birds that survived the drought by black bars. Approximately what percentage of birds with the most common beak depth in 1976 (8.8mm) survived the drought? (Show your work)
