non-metals gain electron and metals lose electrons,
<span>Iron is a metal, so when it reacts it loses an electron becomes a
cation and form ionic bonds. Hydrogen is a non-metal, it gains an electron when
reacting and forms covalent bonds or ionic bonds.</span>
There are 3 main processes in urine formation. These are Filtration, reabsorption and secretion.
Filtration
Blood enters the afferent arteriole and goes to glomerulus where blood is filtered and it will sip inside the glomerulus and nonfilterable components will go into efferent arteriole.
Reabsoprtion
Molecules and ions will be reabsrobed into the system. The fluid will pass into the proximal, distal and convoluted tubules, loop of henle, as water an ions are removed as the fluid osmolarty changes. Last is secretion of substance that is not filtered.
The answer is potential. It is because chemical energy is a
storage of energy that are formed in which making it or why it is considered to
be potential rather than those given choices above in which doesn’t describe
chemical energy.
