An action potential involves potassium ions moving <u>outside </u>the cell and sodium ions moving <u>inside </u>the cell.
<h3>how does it action potential work?</h3>
Neurons have a negative concentration gradient most of the time, meaning there are more positively charged ions outside than inside the cell. This regular state of a negative concentration gradient is called resting membrane potential. During the resting membrane potential there are:
- more sodium ions
outside than inside the neuron
- more potassium ions
inside than outside the neuron
The concentration of ions isn’t static though! Ions are flowing in and out of the neuron constantly as the ions try to equalize their concentrations. The cell however maintains a fairly consistent negative concentration gradient (between -40 to -90 millivolts). How?
- The neuron cell membrane is super permeable to potassium ions, and so lots of potassium leaks out of the neuron through potassium leakage channels (holes in the cell wall).
- The neuron cell membrane is partially permeable to sodium ions, so sodium atoms slowly leak into the neuron through sodium leakage channels.
- The cell wants to maintain a negative resting membrane potential, so it has a pump that pumps potassium back into the cell and pumps sodium out of the cell at the same time.

Answer:
<em> The carrying capacity is determined only by the density-dependent factors.</em>
Explanation:
The maximum number of organisms of a particular species that an environment can hold is known as the carrying capacity of that environment. The carrying capacity depends on density-dependent factors as well as density- independent factors like weather, sunlight etc.
Beyond the carrying capacity, the organisms will begin to fight with each other for limited resources. The environment will become unstable as the resources will be scarce and individuals will be more.

Answer:
pigs suffered severe influenza in the year 2022
Explanation:
Influenza, commonly known as flu, is a viral infectious disease caused by different types of influenza viruses. Some of the most common symptoms of this disease include, among others, headache, coughing, fever, muscle pain, etc. Influenza viruses can affect humans and different animals such as, for example, cats, dogs, birds and horses. There is evidence showing cross-species influenza virus transmission. For example, it has been shown that the influenza type A virus can be transmitted from one species to another (for example, between humans and pigs). In these cases, cross-species transmission information may indicate how much potential a virus has to cause a pandemic in the new host by analyzing the severity and infectivity of the virus in the original host.
