Luke recently moved to a new apartment and wants to grow houseplants but isn't sure which room will be the best fit for them. Apply your knowledge of the scientific method to recommend a strategy for Luke to follow when determining the ideal location for houseplants in his new apartment.
A farmer has noticed that his soybean plants produce more beans in some years than others. He claims to always apply the same amount of fertilizer to the plants, but he suspects the difference in crop yield may have something to do with the amount of water the crops receive. The farmer has observed that the soybeans on his farm usually receive between 0 to 0.5 inches of water per day, but he is unsure of the optimal average daily amount of water with which to irrigate.
1. State a question that addresses the farmer’s problem
2. Conduct online research on “soybean crop irrigation" and record a brief summary of the findings
3. Construct a testable hypothesis and record i
4. Design an experiment to test the hypothesis and describe the procedures, variables, and data to be collected
5. What is the purpose of a control group in an experiment? What would the control groups be for each of your designed experiments in this exercise?
6. Describe the data that would be recorded in each of the…

Drug X was developed to reduce blurred vision in healthy patients, but the effectiveness had not been tested on those suffering from multiple sclerosis. A study was conducted to determine if Drug X is effective at reducing blurry vision in multiple sclerosis patients. To be considered effective, a drug must reduce blurred vision by more than 30% in patients. Researchers predicted that a 20 mg dose of the drug would be effective for treating blurred vision in multiple sclerosis patients by reducing blurred vision by more than 30%. Drug X was administered to groups of multiple sclerosis patients at three doses (10 mg/day, 20 mg/day, 30 mg/day) for three weeks. A fourth group of patients was given a placebo containing no drug X for the same length of time. Vision clarity was measured for each patient before and after the three-week period using a standard vision test. The results were analyzed and graphed (See Figure…arrow_forwardSvp je voulais demander l aide pour mon exercicearrow_forward
- Imagine that you are a clinical geneticist. Your colleague is an oncologist who wants your help explaining the basics of genetics to their patient, who will be undergoing genetic testing in the coming weeks for possible acute myeloid leukemia (AML) induced by the radiation she had several years ago for breast cancer. Write a 1,050- to 1,225-word memo to your colleague. Include the following in your memo: An explanation of the molecular structure of DNA and RNA, highlighting both similarities and differences A description of the processes of transcription and translation An explanation of the differences between leading and lagging strands and how the DNA is replicated in each strand Reponses to the following common questions patients might ask about this type of genetic testing and genetic disorder: Does AML run in families? What genes are tested for?arrow_forwardRespond to the following in a minimum of 175 words: What are some potential consequences that could result if the processes of replication, transcription, and translation don’t function correctly?
