Here's what he must do:
-- Run the experiment again, several times if possible. Combine or
analyze
the results of the several experimental runs in some statistically
valid way.
-- Run the simulation again, several times. Combine or analyze the results
of the several simulations in some statistically valid way.
-- Then, compare the analysis of several experimental runs with the analysis
of several simulations, in some statistically valid way, to decide whether they
<em>really</em> don't track.
-- If they do, then look for ways to tighten up the simulation so that maybe
they can track better.
-- If they don't, then he's back to <em>before</em> Square-1. He not only has to
deal with the question of whether or not his experiment is valid, but he
also has to consider the possibility that his simulation is trash and
doesn't actually model nature like he expected it to.
No. The T-cell has surface receptors made of proteins that are COMPLEMENTARY to only ONE SPECIFIC antigen due to the specific sequence of amino acids resulting in a specific tertiary structure of the protein. Thus, the T cell will only recognise the antigen it’s receptors are complementary to.
The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
