Answer:
too little oxygen in the atmosphere
Explanation:
Possible causes of hypoxia include too little oxygen in the atmosphere. getting very cold too little oxygen in the atmosphere obstruction of the esophagus taking several rapid deep breaths
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).

Since 2000, melting ice from the continent totaled enough to raise sea levels globally by about four tenths of an inch, according to the report which relied on the work of 90 scientists. With what’s already baked into the atmosphere, faster melting land ice will likely add between 7.5 and 9.8 inches to earlier U.N. estimates by 2100, the report said. And because of its position downstream, in an area of “preferential excitement,” South Florida could experience rise at the high end as water sloshes around the planet, Kirtman said. “Think of it as pushing down the ocean [in Greenland]. The ocean is fluid, so it’s going to respond somewhere else and that somewhere else is down here,” he said. In South Florida, planners already confronting flooding from sea rise have been more aggressive in assessing sea rise.

Answer:
Chromatin is responsible for gene expression.
Explanation:
Chromatin is responsible for gene expression because chromatin contains DNA that has all information about genes. chromatin controls the gene in order to form encoded products. DNA in chromatin send information to the RNA to produce specific types of proteins that are needed by the organisms for its growth and development so in that way the genes can be expressed in the organism.
