Something about the Artic Biome And desert biome
Answer:
The oceans are present on the 70 percent of the world but only 5 percent of the total oceans are explored yet.
There are many reasons of this problem but the most important is the hydrostatic pressure.
Hydrostatic pressure can be described as the pressure or weight exerted by the water on the object.
With every increase in 10 meters the pressure increase by 6.47kg (14.27lbs) each square inch of surface.
Due to extreme pressure, oxygen level in the cells of body fluctuates and person becomes unstable and can become unconscious.
<span>Answer: Opening of Na+ and K+
Explanation:
Acetycholine binding opens Na+ and K+ ion channels in the receptors that allow simultaneous passage of Naâş into the muscle fiber and Kâş out of the muscle fiber. More Naâş ions enter than Kâş ions exit, which produces a local change in the membrane potential called the end plate potential.
Binding of acetycholine to receptor proteins opens Na+ and K+ channels resulting in jump in resting membrane potential(RMP) from -90mV to +75mV forming an end-plate potential (EPP).</span>
