¿Qué características crees que deben tener los métodos anticonceptivos para ser eficaces en el control de la natalidad?
Tanzania [10]

Answer:

Los métodos anticonceptivos para ser eficaces en el control de la natalidad deben ser seguros para las personas que los utilizan, es decir, no tener efectos adversos, o al menos, la menor cantidad posible. Ser reversibles, es decir, que no generen infertilidad de por vida. Deben ser además fáciles de usar, cómodos y fáciles de conseguir, esto es, económicos. Además deben ser eficientes en su objetivo de evitar la concepción, que es para lo que fueron creados.

Explanation:

La tasa de eficacia de un método anticonceptivo se mide por la cantidad de embarazos que se producen cada 100. Esta parece ser la característica más importante, y si bien es una de las más importantes, hay que tener en cuenta todos los otros factores mencionados, es decir que la gente pueda acceder a ellos, sean cómodos, seguros y a un precio coherente.

torisob [31]

Answer:

True

Explanation:

Tetrodotoxin is the molecules that act as a poison to the organism in which they are injected.

The tetrodotoxin proves lethal to the organisms as it kills the organism by interfering with the nervous system. The tetrodotoxin blocks the sodium channels in the neuron as a result of which the sodium is unable to enter the neurons and hence the electrical impulse is not generated.

If the tetrodotoxin blocks the motor neuron transmission by blocking the sodium channels then the signals will not reach the muscle and muscle will not be able to contract.

Thus, true is correct.
