Which is the functional unit of the kidney where blood is filtered, water and other dissolved substances are reabsorbed, and waste is sent out to be excreted? ureter alveolus urethra nephron

Hello! Your answer is the nephron.

The nephron is the functional unit of the kidney. There are about one million in each kidney. The nephron has multiple parts, but here's a brief description. The glomerulus is a cluster of nerves/blood vessels/spores, where all waste gets filtered. The rest of the nephron is one long tube. There are multiple parts in this. The loop of henle is where water and salts are reabsorbed. The proximal tubule is where most bulk reabsorption happens. There are many more aspects to the nephron, but these are a few of the more important ones.

The ureter is incorrect, as its function is to bring waste products from the kidneys to the bladder for removal. The urethra is incorrect, as its function is to bring waste products from the bladder and remove them from the body.  The alveoli are in the lungs, and have nothing to do with the kidney. (in general, however they can be more broad)

Hope this helps!

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
