Rh-
blood can receive Rh- blood.

Answer: An Rh+ person can receive Rh+ or Rh-. An Rh- person can only receive Rh- blood
Explanation: the Rhesus (Rh) group has three types, CDE. Of these, only the D locus is of general importance, and this is the one involved when we talk about Rh+ or Rh-. The D allele is dominant and DD or Dd are the Rh+ type, while dd is Rh-.
Rh- people have an immune response to the D and produce antibodies which causes blood clots and this can be life-threatening. Some Rh- people have anti-D antibodies in their blood, but the level is too low to affect Rh+ people transfused with Rh- blood. This is also unlikely because Rh+ is by far the more common type.
A particular problem arises when a mother is Rh- and the father Rh+ because the baby may be Rh+. If this happens the mother will produce antibodies to the foetus’s blood which will kill it if they cross the placenta. This is avoided by giving the mother Rh immunoglobulin injections during pregnancy which switch off anti-D antibody production.
It is rare for the C and E loci to cause a significant immune response.
Answer:
The prefrontal cortex
Explanation:
The prefrontal cortex, which is responsible for higher-order cognitive functions such as decision-making, planning, impulse control, and reasoning, is generally the slowest area of the brain to develop. Its development continues into early adulthood, with significant changes occurring throughout adolescence. This delayed development of the prefrontal cortex is often associated with the development of executive functions and the ability to make complex decisions, which is why teenagers and young adults may sometimes exhibit impulsive behavior or have difficulty with long-term planning.
