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.
A: if the oak trees are I'll then it would affect their health which they'll star dying which means that all the biotic organisms that depended on those oak trees for shelter would also start dying which means all the organisms that depended on the oak tree organisms would also die and so on. That way this small change will affect the whole animal community in that area.
B: this change in biodiversity will greatly affect the sustainability of the forest because the animals dying would disrupt the food chain in that ecosystem while killing the whole forest.

This is a way the doctor can determine if there are any abnormalities.

Answer:
Fossil Evidence and Structural evidence proves to support the theory of evolution because fossil evidence shows how animals looked like a few hundreds to thousands of years ago, and structural evidence shows how an animal can change from a land creature to a sea creator such as a whale starting from Indohyus to becoming a whale as it is now.
