Investigators are interested in the relationship between maternal depression and bacterial vaginosis (BV) prior to delivery. In order to assess the relationship, the researchers attended a prenatal clinic in New Orleans, Louisiana and invited women that attended the clinic to take part in a thorough questionnaire about their pregnancy status. Women had to be in at least the second term of their pregnancy. After the questionnaire, the women were required to undergo a bacterial culture examination to confirm their BV status. Data from the women was collected, and the mothers were categorized as exposed (depressed) or unexposed (not depressed) based on results from the questionnaire as well as diseased (BV ) or non-diseased (BV-) based on the results from the culture analysis. Which risk measurement do you think would be most appropriate to compare the groups

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.
