<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>
<span>The brain is a very complex organ in humans. Although we still have a lot to learn about it, decades of studies in both living and dead humans had revealed that the brain is crosswired, meaning the right side of the brain controls the left side of the body and viceversa. It’s also the part of the brain associated with arts and our creativity. Therefore the answer is B</span>
adenine (A) pairs with uracil (U); guanine (G) pairs with cytosine (C).
There are 56 neutrons. To find them, you just have to subtract the atomic number with the atomic mass. If you dont know, the atomic number is the number of protons (and electrons) in an atom. The atomic mass is the number of both the protons and neutrons. Of you subtract the atomic number, you get protons.
Answer:
Air particles are a mixture of solids and liquids that are microscopically tiny and suspended by air currents. It can stay in the atmosphere for a few hours to a month or two. Their constituents can be various harmful substances such as heavy metals - lead, nickel, arsenic, cadmium or polycyclic aromatic hydrocarbons
Explanation:
Air particles, nitrogen dioxide and ground-level ozone are now considered to be the three most polluting substances in human health. Exposure during peak concentration and long-term exposure to these pollutants can cause damage from respiratory distress to premature death.
