Hi
The answer is: Atlantic Ocean
I hope that's help !
The first person generally
credited with fulfilling the functions of the modern director was George, Duke
of Saxe- Meiningen. Meiningen was a wealthy aristocrat and head of a small
German principality. In 1826, George, Duke of Saxe- Meiningen and his
morganatic wife started an experimental acting group which was one of the first
companies in which the importance of the director was stressed.
The right answer is D (less responsive to antigens)
It is proven that, after puberty, thymus activity (an organ that is included in the lymphatic system, producing T cells that pick up antigens) decreases and that in adult and aged people the thymus has no role. Work done in humans indicate that in fact the cellularity begins to decline from birth in favor of lymphocyte perivascular spaces and connective and adipose tissue, which leads to a decrease in the capture of antigens.
