Describe how ingestion of very salty food may reduce the amount of water excreted in urine​

After filling up on high-sodium foods for a few days, you might notice you feel a bit bloated. Although sodium plays a variety of important roles in the body, too much of the electrolyte can cause harmful effects. To help keep sodium levels within a normal, healthy range, the kidneys alter the production of urine. In fact, the National Space Biomedical Research Institute website claims the kidney's automatic regulation of salt and water in the human body is the single most important factor in determining the volume of urine produced.

Explanation:

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme
