Entry is typically achieved by means of a membrane fusion reac tion occurring either directly at the cell surface following particle binding or in lowpH endosomes after endocytosis of bound virions Enveloped viruses have evolved a diversity of strat.

Crockett et al (2008). carried out a repeated measures experiment on 20 participants. . In . both conditions the participants had fasted and were given a protein drink in the morning before taking part in the study. The difference in the drink was the difference in the conditions: one drink contained tryptophan, which the body needs to make serotonin; the other drink did not contain it. On both days that the study took place participants played the ultimatum game. In this game one player poses a way to split a sum of money with a partner. In the condition where the participants had had the drink that did not contain tryptophan (so their serotonin levels were low) they showed increased aggression toward offers they perceived to be unfair..
