Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. So, if these amino acids are in anyway related to each other, there can be some similar resemblance between the beetles.

Correctly identify each of these definitions or examples as either depolarization or hyperpolarization of the plasma membrane. 1
natulia [17]

Answer:

  1. hyperpolarization
  2. depolarization
  3. hyperpolarization
  4. depolarization
  5. hyperpolarization
  6. depolarization
  7. depolarization

Explanation:

The resting membrane potential is balanced by ion leakage and ion pumping, to get an electrical signal started the membrane potential has to lose its balance. This starts with a membrane channel opening for Na+ since Na+ concentration is higher outside the cell, ions will rush into the cell. This will change the relative voltage inside the cell. The resting potential has a voltage of -70 mV, the sodium cation entering the cell cause it to become less negative. <em>This is known as depolarization.</em>

The concentration gradient for Na+ will continue to enter the cell making the voltage to become positive reaching +30 mV. At the same time, this happens, other voltage-gated channels are also opening, a concentration gradient acts on K+, as well, as it leaves the cell, it takes a positive charge with it making the membrane potential to move back to its resting voltage of -70 mV. <em>This is called repolarization. </em>

For potassium ions to reach equilibrium the membrane voltage needs to be below -70 mV, this leads to a period of <em>hyperpolarization</em> that occurs while the K+ channels are open.

I annexed an image that illustrates this action potential process.

<em>Considering the information given during depolarization there's an increase in the number of sodium leak channels (7) making the inside of the cell more positive (2) increase in the membrane potential (4), this also implies a decrease in the extracellular concentration of potassium (6)</em>

<em>Meanwhile, during hyperpolarization an increase in the extracellular concentration of potassium (3) decreases the membrane potential (1) making the inside of the cell more negative (5).</em>

I hope you find this information useful and interesting! Good luck!<em>       </em>

Which force primarily acts on a natural or artificial satellite to keep it in orbit around a planet
rjkz [21]

Answer:

Gravity

Explanation:

When its altitude is matched by the pull of the Earth's gravity, a satellite circles Earth. The satellite will fly off into orbit in a straight line or crash down to Earth without this equilibrium.

By juggling two things, a satellite retains its orbit: its velocity (the speed it takes to travel along a straight line) and the gravitational force on it that the Planet provides. To resist the greater gravitational force, a spacecraft orbiting closer to the Earth needs more velocity.
