Known as the fraternal birth order (FBO) effect, this theory has been backed up by strong evidence of its prenatal origin, although no evidence thus far has linked it to an exact prenatal mechanism. However, research suggests that this may be of immunological origin, caused by a maternal immune reaction against a substance crucial to male fetal development during pregnancy, which becomes increasingly likely after every male gestation. As a result of this immune effect, alterations in later-born males' prenatal development have been thought to occur. This process, known as the maternal immunization hypothesis (MIH), would begin when cells from a male fetus enter the mother's circulation during pregnancy or while giving birth. These Y-linked proteins would not be recognized in the mother's immune system because she is female, causing her to develop antibodies which would travel through the placental barrier into the fetal compartment. From here, the anti-male bodies would then cross the blood/brain barrier (BBB) of the developing fetal brain, altering sex-dimorphic brain structures relative to sexual orientation, causing the exposed son to be more attracted to men over women.
What does BBB stand for?
****
The answer: blood/brain barrier

10th Street (404403N 740011W / 40.7342580N 74.0029670W / 40.7342580; -74.0029670) begins at the FDR Drive and Avenue C. West of Sixth Avenue, it turns southward about 40 degrees to join the Greenwich Village street grid and continue to West Street on the Hudson River. Because West 4th Street turns northward at Sixth Avenue, it intersects 10th, 11th and 12th and 13th Streets in the West Village. The M8 bus operates on 10th Street in both directions between Avenue D and Avenue A, and eastbound between West Street and Sixth Avenue. 10th Street has an eastbound bike lane from West Street to the East River. In 2009, the two-way section of 10th Street between Avenue A and the East River had bicycle markings and sharrows installed, but it still has no dedicated bike lane. West 10th Street was previously named Amos Street for Richard Amos. The end of West 10th Street toward the Hudson River was once the home of Newgate Prison, New York City's first prison and the United States' second.
Which prison was New York City's first?
****
The answer: Newgate Prison
