Answer:
Explanation:
- Fertilizer during runoff
- Heat, and radiative chemicals
- Yards and runoff
- Heating the water if run by steam by pumping the waste into rivers
- The clean water act focuses on navigation and water as in fishing, and swimming water while the safe drinking water act dictates how water comes to our cups from their original sources.
- You can get information by any sites locally about disposing chemical waste or any government website ending in .gov
- Home waters including sewage have to be filtered through heavy chemical processes using extra waters and factories. our clean water volume is plummeting.
I think Autorhythmic fibers are fibers that are self excitable or on their own for example some cardiac muscle. They repeatedly generate action potentials that trigger heart contractions.They continue to stimulate a heart to beat even when it is removed from the body. In comparison to contractile fibers, autorhythmic fibers are self excitable and do not require nervous system stimulation to trigger contractions. Contractile fibers have stable resting membrane potentials of -90mV, when a contractile fibers reaches threshold by action potential, the voltage gated fast sodium ions channels will open.
<span>The plasma membrane is phospholipid bilayer. The layers are two and are continuous flat sheets. They have proteins and cholesterol embedded in them, for facilitating the transport of compounds and maintanng fluidity. The lipid bilayer is both hydrophobic and hydrophillic. </span>
It was believed that the magnetic field to be generated deep down in the Earth's core. But the truth is the flow of liquid iron generates electric currents, which produces magnetic fields.
But the truth is no one really knows for certain so the only thing we know is that the spin of the earth is the cause of its magnetic field
Hope this helped :)
Have a great day
