How can a mother with the B blood type, having A antibodies in her plasma, carry a baby full-term that inherits the A blood type

DanielleElmas [232]

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.

<h2>Answer: How does the Ebola virus infect people?</h2>

Ebola virus contains a type of genetic material called RNA, which is similar to DNA and contains the blueprint for assembling new virus particles. Unlike animals and plants, which also use DNA as a repository of information, viruses are not technically alive because they are incapable of replicating without help. In order to create new viruses, the virus must infiltrate a living cell, where it hijacks the host cell’s machinery to fulfill its own goals. In order to get into the cell, Ebola must travel through the cell membrane, which is a barrier that protects the cell from its environment. However, all cells need nutrients, which must have ways of entering the cell; the viruses hitch a ride into the cell via one of these established nutrient-uptake entryways. Ebola virus takes advantage of a non-specific engulfing process called macropinocytosis, which allows the virus to be “eaten” by a wave-like motion of the cell membrane (Figure 1) [2].
