Answer:
Dogs are wonderful human companions. They are the first species that humans domesticated and they have a long history of close relationships with people.
If you spend any time with dogs (I have two wonderful adopted dogs who shower me with affection and fur), then you see first-hand the many ways that dogs can respond to their owners. A dog may treat a stranger with suspicion, but dances with joy when its owner returns. Indeed, when one of our grown children returns after a long absence, the dogs respond with excitement.
Solution:
In phylogenetic inference, an evolutionary novelty (or derived character) is referred to as Plesiomorphy
Relating to or denoting the process by which different kinds of living organisms are believed to have developed from earlier forms during the history of the earth.
Thus this is the required answer.
The answer is B.) its reactivity

The lymphatic system has many functions in the human body. Here are the two main ones.
1.) the fat tissue in the body is transported through lymph tissue, part of the lymphatic system.
2.)the lymphatic system also has a significant role in the human defense system. After a pathogen (a disease causing substance eg. Bacteria) has bypassed the general defence system, its up to the lymphatic system to fight these infections.
It does this through the production of antibodies against these pathogens. Cells are produced to produce and antibodies, namely, b and t cells. Examples of these cells include; killer t cells(what it says on the tin.) memory b AND t cells memorise the pathogen so it does not infect you again(induced immunity). Suppressor t cells stop killer cells from destroying normal healthy human cells. These particular cells have a significant role immunity.
Not 100% sure but I think the lymphatic system has a role in the production of phagocytes and monocytes which engulf the bacteria(as opposed to using chemicals to destroy them). Ps. Antibodies recognise pathogens through specific antigens on these harmful cells.
Finally, I believe the lymphatic system can be linked with white blood cells in the production of additional immunity proteins but you may have to do your own research on that!
GOOD LUCK
