Answer:
False
Explanation:
All living things need ribosomes, they are the ones that do the translation of the RNA to form proteins which are essential for the cell to live and to reproduce. Without them the cell will accumulate damage and die in a short period of time due to the fact that it lacks proteins that can act as enzymes, carriers, support of a structure, messengers, etc. In other words, Proteins are of vital importance for the cell and if there is no ribosome that can join the amino acids according to the mRNA sequence there will not be proteins.

The initial exposure of the body to an infectious agent e.g. through a vaccine, triggers an immune response most of which rapidly diminishes after the vaccination. However some cells of the immune system called lymphocytes remain with a memory of that pathogen.As a result, if the same pathogen infects a vaccinated person, the memory cells remember and recognize it and rapidly spring into action triggering a much more rapid response specific to that pathogen than the initial exposure, effectively dealing and neutralizing the pathogen.
