B1202 Biology of Behavior Assignment Constructing a Graph mammals is a hormone that plays a role in childbirth and milk release in n to social behaviors such as attachment, t and fish have e a similar hormone called isotocin. Research has linked oxytocin trust, and the suppression of social would affect the aggressive and anxiety. Researchers wondered whether isotocin submissive behaviors of cichlid fish. Their hypotheses were that decrease rates of aggression and increase submissive behavior needed for social coexistence, because cichlids live in groups. They set up 10 groups of each group they chose one fish and either injected it with isotocin, or a saline solution to serve as a control. After returning the fish to the group, they observed its behavior for 10 minutes, recording all aggressive or submissive behaviors that the injected fish showed towards other group members. One week later they removed the same individuals and, if they had already been injected with isotocin the first time, they were now injected only with saline and vice versa. Thus each fish served as its own control. Here are some of the data the researchers collected. Compile this data and create an appropriate graph. Based on your graph, does the data support or disprove the researchers' hypotheses (explain)? isotocin would fish.

Explanation / Answer

Here we can see that the isotocin submissive bars are mostly protruding in numbers. Therefore, the hypothesis of the scientist that isotocin is increases submissive behaviors and decreases aggression in fish, has followed.
