Bo (dog) Bo (born October 9, 2008) is a pet dog of the Obama family, the former First Family of the United States. Bo is a neutered male Portuguese Water Dog. President Barack Obama and his family were given the dog as a gift after months of speculation about the breed and identity of their future pet. The final choice was made in part because Malia Obama's allergies dictated a need for a hypoallergenic breed.
How do plasma cells form, and how do they help fight pathogens. Answers. Plasma cells, they are also called plasma B cells, or effector B cells, are white blood cells that secrete large volumes of antibodies. They are transported by the blood plasma and the lymphatic system. Plasma cells originate in the bone marrow; B cells differentiate into plasma cells that produce antibody molecules closely modeled after the receptors of the precursor B cell.
The plasma membrane is like the skin of the cell and lets only certain things in and out. It uses active and passive transport to let things in and out meaning that it uses energy only sometimes to let things in and out (this being active) and lets things move as they please at other time (this being passive).
