Use the reseаrch scenаriо tо аnswer the remaining questiоns: Researchers want to determine whether the hormone ghrelin influences food intake in healthy adults. They recruit 120 adult volunteers and randomly assign them to one of two groups. One group receives an intravenous infusion of ghrelin before lunch each day for one week. The other group receives an identical-looking saline placebo. Neither the participants nor the researchers measuring the results know which treatment each participant receives until the study is complete. Each day, participants are offered the same buffet meal, and the researchers carefully measure the number of calories each participant consumes. Participants are also asked to rate how hungry they feel before eating using a standardized questionnaire. All participants provide informed consent, may withdraw from the study at any time without penalty, and are monitored by medical personnel throughout the study. What is the independent variable?

Reаd the text belоw аnd аnswer the fоllоwing question based on the text. “In terms of everyday behavior, the UCLA study found that women are far more likely than men to seek social contact when they are feeling stressed. They may phone relatives or friends or ask directions if they are lost. This difference in seeking social support is one of the most basic differences between men's and women's behavior, according to Dr. Taylor. One of the studies analyzed by Dr. Taylor's team showed how fathers and mothers included in the study responded differently when they came home to their family after a stressful day at work. The typical father wanted to be left alone to enjoy some peace and quiet, or if work was especially stressful, he might react harshly to his children. For a typical mother in this study, coping with a bad day at work meant focusing her attention on her children and their needs. Other researchers looked at how well women functioned after the death of their husband. The death of a spouse is thought to be the worst cause of stress that people can face. They found that women who had close friends and confidantes were more likely to survive the experience without a negative effect on their health or feeling of vitality.” Question 3: Which sentence has the same meaning as this sentence? “The death of a spouse is thought to be the worst cause of stress that people can face.”
