Explanation:

1)

La anatomía es la rama de la biología (una subdisciplina de Ciencias Naturales) que estudia la estructura y forma del cuerpo y sus partes. La fisiología estudia las funciones, la homeostasis es el equilibrio interno, la retroalimentación negativa es un mecanismo de regulación, y la irritabilidad es la respuesta a estímulos.

Los niveles de organización del cuerpo humano, de más sencillo a más complejo, son: molecular (moléculas), celular (células), tisular (tejidos), orgánico (órganos), sistema de órganos (sistemas), y organismal (organismo). Entonces la secuencia correcta es molecular, celular, tisular, orgánico, sistema de órganos, organismal.

La célula es la unidad fundamental (más pequeña) de todos los seres vivos. Las moléculas son subcelulares, los tejidos están formados por células, los órganos por tejidos, y el organismo por sistemas de órganos.

Answer:

A) anatomy
