<span>The question is asking us whether it is true that nonnative species disrupt the natural variability of an ecosystem. This is true. A famous example is the introduction of cats to Australia: they are non-native species and they hunt the native species, therefore reducing the species variability in Australia.</span>
75% species go extinct to be considered a mass extinction
The passage of IgG antibodies from mother to fetus illustrates passive immunity.
- Antibodies produced outside the body can protect a person from contracting a disease, or they can give passive immunity.
- Because antibodies are not regenerated as frequently as they would be in a person with a functioning immune system, passive immunity is typically transient.
- Immunity that is transferred from mother to kid is known as maternal passive immunity or natural passive immunity.
- Antibodies are transferred to the unborn child by the placenta while they are still in the womb and can offer protection against the corresponding infections in the weeks and months after delivery.
- An infant's passive immunity to disease is maintained after birth due to antibodies contained in breast milk, particularly in colostrum, the protein-rich milk produced in the first few days after birth.
- The importance of maternal passive immunity for safeguarding infants until their own immune system is mature enough to protect them.

Answer:
The correct option is A. Theories that are related to the evolution of humans from apes will change.
Explanation:
The research from Dr. Katherine will change the theory of evolution of humans from apes because according to the theory of evolution changes in the genetic sequence of apes caused the formation of humans. But Dr. Katherine Pollard's research says that no deletion or addition of genes took place rather the genome of humans and apes is same with certain switches controlling the genome.
The reaction against your skin is equal to the force put upon the object.
Zero net force is when forces are balanced, ie no velocity.
All forces put on an object have an equal and opposite reaction.
