Knowing a bit about how filters work comes in handy when you're deciding what to buy. A vacuum with proper HEPA filtration will channel virtually all (over 90 percent) of the dirty airstream through the filter; if it doesn't do this, it's simply rearranging the dirt. HEPA filters ...
Describe how a spectrophotometer works. How do you calculate the filtration rate in chromatography? Explain how you could use the melting point to determine the purity of a solid sample. Explain how to convert ppm (g/mL) to mg/L.
How a laser printer works When you print something, your computer sends a vast stream of electronic data (typically a few megabytes or million characters) to your laser printer. An electronic circuit in the printer figures out what all this data means and what it needs to look like on the...
Explain how a thermocouple works. Explain ultra filtration of kidneys? How does the diffusion process work when potassium permanganate crystals are put in water? Why does air pressure decrease with increasing height? Explain the functions of all four types of teeth. ...
Describe filtration at capillaries. Describe three ways in which carbon dioxide can be transported in the blood. Explain how ventilation works, and use the balloon bottle system to explain how the air goes in and out of the lungs during normal respiration...
Explain how hormones regulate endocrine glands. What are the effects of the sympathetic nervous system on the glomerular filtration rate (GFR)? Explain the process for negative feedback in the endocrine system. Explain how urea is involved in conce...

How immunity works with prior infection or vaccination If you have had a prior Covid infection or are vaccinated, your immune system was prompted to develop trained B-cells that quickly produce antibodies that recognize and specifically target the Covid virus, known as adaptive immunity. Neut...
Nucleation: Nucleation is the formation of a new phase having a different composition structure. According to thermodynamics, it can be considered as an ensemble of atoms. Nucleation is very useful in the determination of crystal structure.
