Elephant fossils were observed in a region. Scientists found that these types of elephants don’t currently inhabit that particul
ar region or any other region in the world. The fossils have distinct features that show similarities to features of present-day elephants. What does this information suggest? 1.)The fossils are an extinct species of elephants, and they’re related to present-day elephants.
2.)The fossils are a living species of elephants, and they’re related to ancient elephants.
3.)The fossils are an extinct species of elephants, and they’re not related to present-day elephants.
4.)The fossils are a living species of elephants, and they’re not related to ancient elephants.
Answer: The correct answer is- 1.) The fossils are an extinct species of elephants, and they’re related to present-day elephants.
As per the information given in the question, Elephant fossils were observed in a region and those elephants do not exist anywhere ( indicating that they have become extinct). As the fossils show similarities to the features of present-day elephants, therefore, this information suggests that they are related ( primarily because of common ancestry) to the present day elephants.
Plasma cells are designed to churn out Antibodies. These are proteins that have a variable region which is complementary ( perfect shape fit) for the virus' antigen and can therefore bind to the antigen, making the virus harmless or tagging it to be consumed by a phagocyte.
