Put the following events in order from the OLDEST to the MOST RECENT. A Homo sapiens migrated out of Africa and throughout Europe and Asia, where they coexisted with other Homo species (such as H. erectus and H. neanderthalensis). B Homo sapiens first appeared in Africa. They had larger brain sizes, smaller teeth, and reduced brow ridges compared to pre-modern hominins such as H. erectus and H. ergaster. C Homo sapiens replaced all previous Homo species and became the...

1)You inject a mouse with a protein antigen X. This is the first time the mouse has been exposed to X. In the course of clearing X from their body the mouse will launch an immune response to antigen X. Over the course of the immune response antigen X will encounter naïve, effector and memory lymphocytes (B- and T-cells). There are distinct differences between the function and role of each type (naïve, effector and memory).Differentiate between naïve, effector and memory lymphocytes. Focus...
