If you're Rh-negative and your baby is Rh-positive, your body will react to the baby's blood as a foreign substance. Your body will create antibodies (proteins) against the baby's Rh-positive blood. These antibodies usually don't cause problems during a first pregnancy.
One point perspective definition. One-point perspective is a type of linear perspective. All categories of linear perspective include a horizon line and a stationary point (the position of the observer). In one-point perspective, only one vanishing point exists; lines radiate outwardly from this point, and perpendicular lines meet at this point. One-point perspective is the same as parallel perspective.

Prior to this, there wasn't an expectation that paintings would be realistic, or naturalistic, representations of life.
