The most powerful solar storms send coronal mass ejections (CMEs), containing charged particles, into space. If Earth happens to be in the path of a CME, the charged particles can slam into our atmosphere, disrupt satellites in orbit and even cause them to fail, and bathe high-flying airplanes with radiation.

Lena [83]

Answer:

Bíceps- tríceps

Explanation:

Los músculos trabajan para generar movimiento mediante la contracción de células musculares. El bíceps y el tríceps son músculos antagonistas presentes en el brazo. Cuando el brazo se acorta, el bíceps funciona como agonista (es decir, se contrae) y hace que los tendones que tiran de los huesos del antebrazo puedan doblarlo. Durante este movimento, el triceps funciona como antagonista, encontrándose en estado de relajamiento. Por otra parte, durante el estiramiento del brazo, las funciones de estos músculos se invierten, con lo cual el tríceps (agonista) se contrae  y el bíceps (antagonista) se relaja.
