Step by step
Solved in 2 steps
- what is the response variable and explanatory variable for wrapping a banana in plastic wrap and leaving the other bananas alone to see which one rots faster in experimental study design?How do I use random assignment for observational study design to test what makes a banana ripen quicker using a banana that's wrapped in plastic and one that's not wrapped in plastic? what what is the response variable and what is the explanatory variable?State all the farming techniques or technologies humans use to grow a rice.What is the importance of the rice in human story?
- Please give an example of experimental research . Why this resesrch is beneficial?Experiments usually have several controlled variables. These are variables that must be kept constant in all parts of an experiment. For example, if an experiment is testing the effect of sunlight on the growth rate of 5 seeds, the only variable that should change should be the amount of sunlight. All other variables should remain the same to ensure that sunlight is the only aspect affecting the results. The other variables, such as soil type, amount of water, type/amount of fertilizer, are the controlled variables. Looking back at the simulation experiment on the meteorite, describe two variables that should have been controlled.Experiments usually have several controlled variables.

- A 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?State all the farming techniques or technologies farmers use to grow a sweet potato and why sweet potato is essential for us humans?Give two examples of how genetic engineering has improved or mightpotentially improve food quality.
- PLEASE HELPPLEASE HELPirections: Answers must be in essay form. Outline form is not acceptable. Labeled diagrams may be used to supplement discussion, but in no case will a diagram alone suffice. It is important that you read each question completely before you begin. An agricultural biologist was evaluating two newly developed varieties of wheat as potential crops. In an experiment, Seedings were germinated on moist paper towels at 20°C for 48 hours. Oxygen consumption of the two-day-old seedlings was measured at different temperatures. The data are shown in the graph below. CUMULATIVE OXYGEN CONSUMPTION O Variety A 7"C - Variety A 17e O Variety B 7°C • Variety B 17°C 20 40 Time (min) 60 8. In a second experiment, variety A seedlings at both temperatures were treated with a chemical that prevents NADH from being oxidized to NAD*. Predict he most likely effect of the chemical on metabolism and oxygen consumption of the treated seedlings. Explain your prediction. v + , N - C (qu) Oxygen Consumption
