Because chemistry is what the body is made up of. It explains the elements in the system and how each effects the biological processes. Chemistry and biology go hand-in-hand because there are tons of chemical reactions and chemistry components within the body.
Answer:
The smallest organisms found on Earth can be determined according to various aspects of organism size, including volume, mass, height, length, or genome size.
Prior to therapy, a high PpIX fluorescence was observed in three patients; however, after iPDT, this fluorescence was entirely photobleached. These patients' viable tumor sections had high PpIX concentrations (mean PpIX uptake per tumor: 1.4-3.0 M).
<h3>Briefing:</h3>
However, no or just minimal PpIX uptake (0-0.6 M) could be seen in the remaining two cases. Strong PpIX uptake patients demonstrated therapeutic response and long-term clinical stabilization (no progression at 29, 30, and 36 months); the remaining two patients experienced early treatment failure (death after 3 and 9 months).
<h3>Describe fluorescence:</h3>
Two steps make up the chemical process of fluorescence first, a chemical fluorophore such a protein or carotenoid absorbs shorter-wavelength light (excitation), and then some of the absorbed energy is released as longer-wavelength light (emission).

Answer:
Resting on top of
Forceps
Buried in
Explanation:
1. The antibiotic disk is gently placed directly above the plates and spread across the plate to allow easy sectioning of the disk - since an antibiotic disk contains different antibiotics whose rate of effect we intend to measure against a particular bacteria. After sectioning, the antibiotic in the section with the largest zone of inhibition is considered more effective against the bacteria.
2. The forceps must also be sterilized before using it to pick-up the disk to avoid contamination. Forceps are used because it is easily sterilized and safer to use - since we are most likely dealing with an infectious agent - using the fingers will not only contaminate the plates, but it could equally be harmful to the handler.
3. It is necessary that the disk must be pressed onto the surface of the plate - to enhance the interaction between the plate and the antibiotics on the disk so as to use the antibiotics optimally.
