David wants to recruit full-time working adults older than 35 years of age for his study on sleep and exercise habits. Since he is not recruiting undergraduates from the Introduction to Psychology research pool

A. he does not need to provide any other information about participant recruitment in his IRB application. As long as he includes an appropriate consent form in his application, the IRB will likely not raise questions.

B. he needs to provide an example of a recruitment flyer or advertisement that he will be using to recruit his participants.

C. he is unable to submit an application through the usual route because he is not using the undergraduate research pool. He will need to talk to the IRB committee to determine his next step.

Explanation: Hope it helps :)

the arab empire adopted the muslim religion as their main belief. arabs would influence the people from the territories they invaded towards islam (the muslim belief).

nevertheless, throughout the history of the arab empire, rulers brought intellectual individuals from other religions to their centers of learning. these other foreigners included jews, christians, greeks, persians, and indians.   these resulted in the adoption of important knowledge developed by these cultures by the arabic empire. for example, the works of aristotle were translated from greek to arab and indian scientists brought the numerical concept of "zero" to the arabs.

nowadays, 93% of the arab population is muslim, which at the same time is subdivided in sects including the sunni, zaini, alawi, shia. the remaining 7% is composed mainly of christians.

for many centuries there were important factors which the economies of the muslim empires developed increasingly. they applied economic procedures in production, investment, finance, taxation and property. they used to tax certain goods (for example: harvest), they charged interest on money lent, they signed contracts with merchants; they relied on a common currency, and they used checks as well as promissory notes. with the money collected by means of taxation, the government provided the needy with an income. in addition, trading networks covered huge distances, so far regions started to have contact and exchange goods. this trade network covered areas of asia, africa and europe.
