The main substance re-absorbed into the blood in the nephron are glucose, electrolytes (sodium, potassium, chloride) and water.
Almost all the glucose is reabsorbed at the proximal tubule of the nephron. Sodium, potassium and chloride are reabsorbed at the ascending loop of Henle, and water is reabsorbed at the descending loop of Henle.
Other nutrients that are reabsorbed are magnesium, phosphates, carboxylate, bicarbonate, amino acids, some urea, proteins and oligopeptides.
Reabsorption occurs in two steps namely active or passive extraction of sustances from the fluid in the tubules of the nephron, and into the interstitium , then transport of these substances from interstitium and into the bloodstream.
Microinjection is a simple mechanical process usually involving an inverted microscope with a magnification power of around 200x (though sometimes it is performed using a dissecting stereo microscope at 40–50x or a traditional compound upright microscope at similar power to an inverted model).

Weathering is the only one that doesn't deal with plate tectonics
Increase in air pollution: public transport
decrease in trees: plant new trees
loss of bird habitat: nesting boxes
endangered aquatic species: regulate recreational activities
Metabolism is a set of chemical reactions happening within an organism. These reactions are necessary to maintain the living state of cells, allowing them to reproduce, grow, and respond to environment.
