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.
Pap smear (Papanicolau smear) is a procedure that involves swabbing the endocervix (inner part of the cervix), ectocervix (outer part of the cervix), and the vaginal walls. This smear will then be fixed and then viewed through a microscope to check for atypical cells (or cancer cells). Pap smear has a 95% sensitivity so pap smear can detect cervical carcinoma 95% of the time.

During ionization process, it leads to the formation of two ions namely a positive ion called
, whereas a negative ion called
. Due to the formation of
ions, which is nothing but a proton, the carboxyl group present in the amino acid act as an acid.
