Essay Title: Ecology1. Need a 5 paragraph Essay about Ecology.2. no Maximum amount of words needed.

A recent study on crime rates examines whether crime depends on sunshine. A researcher hypothesizes that sunshine makes people happy and thus reduces crime. She collects data from cities across the USA and their sunshine exposure, runs a regression and finds the following:Dependent Variable: Number of Crimes per 100,000 people (higher scores mean more crime)R2 = .45Estimate Std.Error. Sig or p-valueIntercept 2.1* 0.05. 0.000Sunny Days 0.5. 0.90 0.540Interpret the estimated slope, estimated intercept, and R2 from this regression. State whether the slope is statistically significant, how you reached that conclusion, and what statistical significance means in this case.

Is there any way to prevent this condition?14. What is the difference between herpes simplex type 1 & 2?15. Can HSV still be spread even if lesions are not present?

What are some risk factors for the development of osteoporosis? See Chart 41-7.Name some health promotion activities to prevent osteoporosis that we should teach to patients. See Chart 41-5.The biggest risk for patients with osteoporosis is that they are more prone to fractures. What are some nursing interventions & strategies we can do to help prevent falls & fractures in patients with this condition? What are some nursing considerations to be mindful of when giving patients prescribed bisphosphonates as treatment for osteoporosis?. What is osteomyelitis? What is the most prevalent causative agent? What are some of the clinical manifestations of this condition? What is the primary medical treatment that is prescribed to treat this condition? What may be indicated if pharmacological management is not successful in treating this condition?

What is the motivation for the study – what is the broad problem in the field that the study helps to address?What is the specific hypothesis being tested?What is the experimental approach to testing the hypothesis? What was measured?What were the important quantitative results? Explain whether the results support or contradict the hypothesis. What do the results mean in terms of the broader issues that motivated the study?

In our Lab Report Assignment, you will consider how different systems may interact and cause changes in an organism’s physiology. While these reports will be based on hypothetical experiments of your own creation, accurate physiological principles and scientific ethics must be adhered to.Consider the different physiological concepts we cover each week in the course. Select two basic physiological concepts from two separate weeks that interest you!1. Design an experiment/set of experiments that you could conduct to further explore how these physiological concepts interact with each other. Simple, straight forward experiments usually yield straight forward figures and hypothesizes… which is what you want!2. Communicate what your hypothesized outcomes are (as long as your thinking has solid physiological principles and references behind it, there’s no wrong answer).Each scientific journal uses a slightly different formatting style, but most share a few common characteristics, which include an: 1. Introduction, 2. Materials and Methods, 3. Results and Discussion, and 4. References.-At least two scientific references (ie. two scientific articles in journals; textbooks and encyclopedias may be used, but do not count as scientific references for this assignment) should be cited in your lab reports. —Two figures are expected for this assignment (refer to the lab report instructi
