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.
The most prominent organelle that contains genetic material and is visible in most eukaryotic cells is the Nucleus.
<h3>What is Nucleus?</h3>
- The nucleus is a double membraned organelle found in all eukaryotic cells.
- It is the largest organelle, which functions as the control center of cellular activities and is the storehouse of the cell's DNA.
- The nucleus is dark, round, and surrounded by a nuclear membrane.
- Within the nucleus, there are tiny spherical bodies called the nucleolus. It also carries an essential structure called chromosomes.
- So the nucleus is the organelle that is visible and present in all eukaryotic cells.
