If the na+ voltage-gated channels in a muscle cell open, what will be the result?

sammy [17]

If the Na+ voltage-gated channels in a muscle cell open, the Na (sodium) ions rush inside the muscle cell and makes the cell more positive as Na ions carry positive charge on it. Due to the entry of positively charged ions inside the cell, the cell becomes less negative and more positive. This is called depolarization of cell.

Step2247 [10]

Answer:

1. The adaptation of the garter snake to the increasing toxicity of the rough-skin newt

2. The development of antibiotic-resistance by the tuberculosis bacteria in prisoners in Russian prisons

3. The development of FIV-resistance in wildcats

4. The immunity to HIV in about 10% of caucasians due to mutations in their cells that occured among those who survived the Black Death.

5. The development of immunity to asthma in children exposed to livestock at an early age in Bavaria

Explanation:

Coevolution refers to the the evolution that occurs in two species of organisms due to the mutual interaction or interdependence of the two species. Due to this interaction among species, a change in one organism results in adaptive changes in the other organism as well.

Coevolution can occur is any of these relationships between organisms: predator-prey, mutualism, or commensalism.

In the movie, Evolutionary arms race, the following examples of coevolution were highlighted:

1. The adaptation of the garter snake to the increasing toxicity of the rough-skin newt.

2. The development of antibiotic-resistance by the tuberculosis bacteria in prisoners in Russian prisons.

3. The development of FIV-resistance in wildcats.

4. The immunity to HIV in about 10% of caucasians due to mutations in their cells that occured among those who survived the Black Death.

5. The development of immunity to asthma in children exposed to livestock at an early age in Bavaria.
