When studying an earth worm, we could see all the amazing things God gave this creature and how it survives. If we dissect an earthworm, we will probably find out that it has multiple flexible parts that allow it to move around under ground. We could test this by filling a see through tank of some sort with dirt and water. We find an earthworm and let it stay in. We could examine that the worm stays on the surface for a little and than proceeds to its hole making. After a while, we could examine the tank and find that the dirt has many holes around it. Eventually let the worm go! This project could teach you something about worms. Worms are also helpful creatures. They provide the plants all the nutrients they need. 

Hopefully I helped your question... but please make sure it's school related because people lose there time on, to answer these for you! :) I was happy to help! :) ;)

Aleksandr-060686 [28]

Answer:

a. Odds ratio = 1.58

b.  Inasmuch the odds ratio is greater than 1, this means that higher odds of melanoma exist in people exposed to indoor tanning, than in those not exposed to indoor tanning

Explanation:

For case  study                                                  

Let 'a'  represent the total population of people with melanomia = 696                                                      

Let 'b' represent the total number of people with melanomia exposed to indoor tanning  =  1107 – 696 = 411 people

For  control study

Let 'c' represent the total population = 1500

Let 'd' represent the total number of people not exposed to indoor tanning = 1500 - (0.428 * 1500)

                                                          =  1500 - 723

Total number of people not exposed to indoor tanning   = 777 people

                                                       

a. Odds ratio = (a/b) / (d/c) = (696/411) / (777/723)

                                                = 1.69 / 1.07 = 1.58

b. Inasmuch the odds ratio is greater than 1, this means that higher odds of melanoma exist in people exposed to indoor tanning, than in those not exposed to indoor tanning.
