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

me two

explanation:

because i hate it

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.
