During adolescence, the human body undergoes various physical, physiological and immunological changes triggered and mediated by hormones, of which the most significant in females is 17--oestradiol (an oestrogen) and, in males, is testosterone. Oestradiol usually begins to act around the age of 10 and testosterone some months later. There is evidence that these steroids act directly not only on the primary and secondary sexual characteristics but also have an effect on the development and regulation of the immune system, including an increased risk in developing pubescent and post-pubescent autoimmunity. There is also some evidence that cell surface receptors on B cells and macrophages may detect sex hormones in the system.
Evidence suggests that receptors on B cells may do what?
****
The answer: detect sex hormones in the system

The expansion of the Rus' put further military and economic pressure on the Khazars, depriving them of territory, tributaries, and trade. In around 890, Oleg waged an indecisive war in the lands of the lower Dniester and Dnieper rivers with the Tivertsi and the Ulichs, who were likely acting as vassals of the Magyars, blocking Rus' access to the Black Sea. In 894, the Magyars and Pechenegs were drawn into the wars between the Byzantines and the Bulgarian Empire. The Byzantines arranged for the Magyars to attack Bulgarian territory from the north, and Bulgaria in turn persuaded the Pechenegs to attack the Magyars from their rear. Boxed in, the Magyars were forced to migrate further west across the Carpathian Mountains into the Hungarian plain, depriving the Khazars of an important ally and a buffer from the Rus'. The migration of the Magyars allowed Rus' access to the Black Sea, and they soon launched excursions into Khazar territory along the sea coast, up the Don river, and into the lower Volga region. The Rus' were raiding and plundering into the Caspian Sea region from 864, with the first large-scale expedition in 913, when they extensively raided Baku, Gilan, Mazandaran and penetrated into the Caucasus.
What year were the Magyars and Pechenges drug into the war?
****
The answer: 894

In 1935, Reza Shah requested the international community to refer to the country by its native name, Iran. As the New York Times explained at the time, "At the suggestion of the Persian Legation in Berlin, the Tehran government, on the Persian New Year, Nowruz, March 21, 1935, substituted Iran for Persia as the official name of the country." Opposition to the name change led to the reversal of the decision, and Professor Ehsan Yarshater, editor of Encyclopdia Iranica, propagated a move to use Persia and Iran interchangeably. Today, both Persia and Iran are used in cultural contexts; although, Iran is the name used officially in political contexts.
When did Reza Shan request that Iran officially be referred to as Iran and not Persia?
****
The answer: 1935

In the light of Mother F. A. Forbes research and reference to Pope Saint Gregory's writings, it would appear that Athanasius was constrained to be Bishop: She writes that when the Patriarch Alexander was on his death-bed he called Athanasius, who fled fearing he would be constrained to be made Bishop. "When the Bishops of the Church assembled to elect their new Patriarch, the whole Catholic population surrounded the church, holding up their hands to Heaven and crying; "Give us Athanasius!" The Bishops had nothing better. Athanasius was thus elected, as Gregory tells us..." (Pope Gregory I, would have full access to the Vatican Archives).
Was there someone else that was preferred as Bishop?
****
The answer:
The Bishops had nothing better
