Three years later, as March 1865 ended, the Confederate capitol became indefensible. On March 25, Confederate General John B. Gordon's desperate attack on Fort Stedman east of Petersburg failed. On April 1, General Philip Sheridan, assigned to interdict the Southside Railroad, met brigades commanded by George Pickett at the Five Forks junction, smashing them, taking thousands of prisoners, and encouraging General Grant to order a general advance. When the Union Sixth Corps broke through Confederate lines on Boydton Plank Road south of Petersburg, Confederate casualties exceeded 5000, or about a tenth of Lee's defending army. General Lee then informed Jefferson Davis that he was about to evacuate Richmond.
What general commanded the attack on Fort Stedman?
John B. Gordon

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-β-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?
detect sex hormones in the system

al-Qarawīyīn University in Fez, Morocco is recognised by many historians as the oldest degree-granting university in the world, having been founded in 859 by Fatima al-Fihri. While the madrasa college could also issue degrees at all levels, the jāmiʻahs (such as al-Qarawīyīn and al-Azhar University) differed in the sense that they were larger institutions, more universal in terms of their complete source of studies, had individual faculties for different subjects, and could house a number of mosques, madaris, and other institutions within them. Such an institution has thus been described as an "Islamic university".
What types of degrees were earned at al-Qarawiyin University?
all levels
