Answer:

The mother can carry a full-term baby with A blood type because the mother's blood does not mix with the baby's blood, so the mother's immune system does not activate attacking the baby.

Explanation:

The reason why a mother with B blood type and A antibodies in her system can carry a full-term pregnancy is thanks to the placenta. The placenta is a shared organ between the mother and the baby. Its function is to protect the baby and produce the necessary exchanges of nutrients and wastes between the maternal blood and the baby's blood. As the two types of blood are separated, and they never get in contact during pregnancy, the immune system of the mother does not recognize the baby as a treat. The mother can have A antibodies in her plasma due to a previous pregnancy where during delivery, the two types of blood mixed, also it can be due to any contact with the A blood type. When the foreign blood enters the body, the immune system forms antibodies for it.

How does one determine the number of protons, neutrons, electrons in an atom
KengaRu [80]

Remember that the number of electrons are equal to the number of protons, and to find the number of protons you have to look and see the atomic mass of the atom is equal to the number of protons, and to find the number of neutrons you have too subtract the atomic mass to the atomic number.

Example:

You want to find out how many protons, neutrons, and electrons are in Platinum:

  • Atomic number is equal to the number of protons:
  • 78 = 78
  • So platinum has 78 protons and electrons.
  • Subtract atomic mass to atomic number:
  • 195 - 78 = 117 (forgetting about the decimals)

So platinum has "78 protons, and electrons, and has 117 neutrons."

Hope this helps!
