Explanation:
is this an actual question!?? lol!
Answer:Chromatography is actually a way of separating out a mixture of chemicals, which are in liquid or gas form, by letting them flow slowly past another substance, which is either a solid or a liquid. It consist of a stationary phase and a mobile phase.
Explanation: All chromatographic systems rely on the fact that a substance placed in contact with two unmixable phases, one movable phase and one stationary phase, will equilibrate between them. A selectivity (or separation) factor (α) is used to 'chemically' distinguish between sample components. It is usually measured as a ratio of the retention (capacity) factors (k) of the two peaks in question and can be visualized as the distance between the apices of the two peaks. reproducible fraction will partition into each phase, depending on the relative affinity of the substance for each phase. A substance which has affinity for the moving or mobile phase will be moved rapidly through the system. A material which has a stronger affinity for the stationary phase, on the other hand, will spend more time immobilized in that phase, and will take a longer time to pass through the system. Therefore, it will be separated from the first substance. By definition, chromatography is a separation technique in which a sample is equilibrated between a mobile and a stationary phase. A theoritical plate or tray is used to produces the best possible difference between the liquid and vapour phases in equilibrium with it
Chromatographic separations are best done with a small amount of analyte (substance to be separated during analysis), which keeps either phase from becoming saturated with analyte, so that the concentrations in the two phases are directly proportional. Overloading the column with sample causes one of the phases to become saturated, leading to a loss of column efficiency, and poorly shaped peak profiles.
The retention volume in chromatographic separation (Vr) is the volume of the mobile phase required to carry the solute through the column to elution, is related to the column flow (Fc) and the retention time (tr). Likewise, the volume of the mobile phase(Vm), is related to the flow and the time the void volume takes to pass through the column.
Band broadening using the kinetic model is a phenomenon that reduces the efficiency of the separation being carried out, leading to poor resolution and chromatographic performance. This is problematical in terms of both the quality of the separation obtained and the accuracy with which sample components can be quantified.The wider band results in a dilution effect that produces a decrease in peak height accompanied by a loss in sensitivity and resolution. The eddy dispersion, accounts for the source of band broadening related to any flow unevenness in the column.
Newspaper articles and farmers harvest yield record are the documents should Dina examine in order to assess this climate data.
Among atmospheric scientists is a group known as paleoclimatologists. There were 11,800 workers in this field in 2014, albeit not all of them were climatologists or paleoclimatologists, according to BLS data. With 40% of the workforce, professional, scientific, and technical services was the main employer of atmospheric scientists.
<h3>What level of education is required to work as a paleoclimatologist?</h3>
Your future work as a paleoclimatologist will involve a lot of biology, physics, and other hard sciences, thus there are lots of degree programs that mix these fields with the environment. Environmental biology and environmental chemistry are two examples of such options.
<h3>How far into the past can paleoclimatology take us?</h3>
Paleoclimatology makes extensive use of polar ice sheets and ice caps as well as mountain glaciers. Data from ice-coring efforts in the ice caps of Greenland and Antarctica date back over 800,000 years in the case of the EPICA project, or several hundred thousand years.
<h3>
Why is paleoclimatology essential and what does it entail?</h3>
Our knowledge of Earth's climate depends on the science of paleoclimatology. Scientists can create models to help predict how rising carbon dioxide levels and other changes can affect the climate of Earth in the future as they become more aware of how climates have been influenced in the past.

Answer:
yes
independent - temperature
dependent - amount of sugar dissolved
Explanation:
When water molecules are heated they move faster and collide more with the sugar molecules. These collisions transfer energy to the sugar molecules. Energy is needed to break bonds. The bonds holding the sugar molecules together or more likely to be broken.
The amount of sugar dissolved is dependent on the temperature of water.
it is not because trees do not grow fast enough
