La respuesta correcta para esta pregunta abierta es la siguiente.

Los tres avances científicos más importantes, a través de la historia para la humanidad son los siguientes.

1.- El descubrimiento de la penicilina.

El científico Inglés Alexander Fleming fue el descubridor de la penicilina en septiembre de 1928. Este descubrimiento revolucionó la historia de la humanidad.. Antes, millones de personas morían debido a las infecciones en el cuerpo humano. La penicilina resultó ser el antibiótico más efectivo descubierto hasta el día de hoy y ha salvado millones de vidas humanas desde su descubrimiento.

2.- El descubrimiento de la electricidad.

¿Te puedes imaginar un día de tu vida sin luz?

Bueno, pues así vivió la gente toda la vida hasta el siglo XVIII, cuando comenzó a entenderse y desarrollar mejores maneras de producir electricidad. Prácticamente todos los aparatos electrodomésticos, de laboratorio, hospitales, en oficinas, escuelas y demás, funcionan con electricidad. Sin ella, nuestra vida no habría producido los avances que conocemos el día de hoy.

3.- El internet.

La revolución de este siglo.

El internet nos mantiene conectados todo el tiempo a cualquier parte del mundo. Con el internet podemos hacer miles de cosas desde nuestras computadoras y teléfonos celulares, que hasta hace 15 años eran inimaginable.

Evaluate the following statement: Volcanoes are only found along coastlines.<br><br>Please help​
d1i1m1o1n [39]

Hey :) hope your day is going well. :P I listed some information below, that may or may not help!

<em>"Evaluate the following statements. volcanoes are only found along coastlines."</em>

<u><em>False!</em></u>

<em><u>Most are found along plate boundaries and hot-spots. :) </u></em>

They are found along plate boundaries because when the plate's collide together, <u>they may leave cracks</u> behind and may turn later into small hills and eventually grow even larger as time goes, and <u>produce magma from under the earth's layers</u>.

Hope this helped you, and as always remember if you need any more help, mssg me and i'll answer any questions you may have. <u>Have a great day.  :)</u>
