Textbook Question
Chapter 22, Problem 16PIAT
PROCESS OF SCIENCE When a statistical test was used to compare the results for white models versus brown models, the P value (see BioSkills 3 ) was 0.01 for each habitat. Does this result increase or decrease your confidence in your take-home message? Explain.

In any scientific paper, the Discussion is often the most hard-hitting, and where researchers elaborate and explain their results in the context of their experiment and the real world. Explain why when researchers tried culling some of the elk herd it did not have trophic effects, while reintroducing wolves did have trophic effects.
A. Why do we need to test the null hypothesis instead of just proving an alternative hypothesis?
B. You are testing the effect of a particular fertilizer on a plant's growth. Your control plants don't get fertilizer while your test plants do. What would be your hypotheses and the null hypotheses?
Experiment with fish tank and algae
Design an experiment with the scenario described below. The scenario gives you the observation. Please label your question, hypothesis, predication, and how you would design your experiment. You have access to any materials that you need for your experiment. Include a label for the standardized controls, independent variable, and dependent variable.
You observe that your five-gallon fish tank that sits on your windowsill grows algae very quickly.

Construct a simple hypothesis.arrow_forwardA team of researchers is interested in testing the amount of oxygen gas (O2) produced when the same species of plant is exposed to different colors of visible light. The research team has developed a hypothesis to test and designed experimental conditions to run. They have submitted the work to you for feedback and approval. Your job is to provide feedback concerning both the hypothesis and the experimental design. This will enable them to make the necessary changes to obtain approval for their research. The Team’s Hypothesis: The levels of oxygen gas will be higher for plants exposed to visible red light. How would you improve the hypothesis while also putting it into a proper hypothesis with an IF and THEN statement?arrow_forward
- +++ NA b. Macroinvertebrates-invertebrates that you can see without magnification-are indicator species often surveyed when assessing aquatic ecosystems. The following data table and graph represent macroinvertebrates sampled in two different streams, Stream A and Stream B. Using the data, develop a claim about the overall and relative water quality of the streams and support your claim with at least two pieces of evidence for each stream. Claim: Evidence: Total Biomass (g) Macroinvertebrate Species Name Mayfly nymph Caddis fly larva Freshwater shrimp Water louse Bloodworm Sludge worm 120 100 80 60 40 20 0 Pollution Tolerance Intolerant Moderately intolerant Moderately intolerant Moderately tolerant Moderately tolerant Tolerant Total biomass in sample (g) Stream A Stream B 0 0 Macroinvertebrate Biomass Comparison 4 30 70 34 10 2 G Mayfly Caddis fly Freshwater Water Bloodworm Sludge nymph larva shrimp louse worm Stream A Stream B 1 4 45 100arrow_forwardFor this experiment, you will be able to manipulate only one variable. First, the amount of water; this means the water in the experimental group is more or less than the control, hopefully not killing the experimental group, but just altering the growth rate of the experimental group compared to the control group. Second the amount of nutrients; nutrients can be varied if you have some plant food or fertilizer at home to use. Third, simulated herbivory is an interesting variable to use. If used herbivory as your experimental variable, decide on a pattern and amount of herbivory to inflict on the plants of the experimental group and write down the procedure in detail. Experiment to test how one of the following variables impacts the growth of Brassica rapa: Water, Nutrient Availability, and Herbivory. 1) Write down just one name of the variable. This is the independent variable. 2) Write down a question to address by manipulating the variable. 3) Next, formulate a hypothesis that…arrow_forwardIn an experiment you grow three different experimental plant plots: a control (no herbivores or nutrients), plants with herbivores, and plants with added nutrients (herbivores still present).

- Treehoppers have a major predator, the jumping spider. Researchers hypothesized that the ants would protect the treehoppers from the spiders. In an experiment, researchers followed study plots with ants removed from the system and compared them to a control plot.

- After spraying your yard with a weed-killer you notice that you don't see any bees in your yard for the next few days. You know that bees are a keystone species that is critical for a healthy environment, and want to investigate if there is a connection between the weed-killer and the absence of bees. Task: Design an experiment that could test this association by describing each of the following points with a sentence: Describe your hypothesis: Describe your dependent variable: Describe you independent variable: Describe your positive control group: Describe a negative control group:arrow_forwardSuppose you want to examine the effect of a fertilizer on the size of eggplant produced, and therefore, you need to establish the experimental and control groups.

She purchases two different types of lamps from a local store. Mina applies brand A to one area of the yard and brand B to another area of the yard, both of which receive full sunlight. She waters the area with brand B daily; she waters the area with brand A every other day. At the end of the study, Mina concludes brand B is more effective in growing strawberry bushes. Mina's conclusion valid? Explain why or why not.arrow_forward
