I believe you meant to say is this mistake called a base pair and if that is your question then no. it would be called Mutation. But you can double check that answer.
Answer:
(2) exchange food, oxygen, and waste between
mother and fetus
Explanation:
In most mammals like humans, the fetus produced as a result of the fertilization of the sperm and egg, develops in the uterus or womb of the female. However, this developing fetus cannot yet fend for what it requires for survival and is still dependent on the mother e.g nutrients, oxygen etc. How do this substances get to the fetus? Here comes the role of the PLACENTA.
Placenta is an organ in the uterus that serves as a connection between the mother and the fetus in her womb. The placenta enables the mother to pass digested nutrients to the fetus and exchange gases (oxygen and Carbondioxide) between them via the umbilical cord. The placenta also enables the mother remove waste produced by the fetus into her bloodstream.

1. Respiration-process by which plants release CO, while they break down the sugar
2. Animals eat plants- They break down sugars and starches by a process of metabolism and the products are energy water, and CO2 molecules.
3. Decomposition-when plants die, their parts (wood, leaves) decay bringing the carbon into the ground
4. Root respiration- respiration that occurs in roots, adds to soil respiration (the amount of CO2 produced through root respiration is determined by the root biomass ).
Answer:
Get the atoms to press together with pressure so that they fuse.
