Los seres invertebrados y los vertebrados tienen más elementos en común de lo que se pensaba. Un estudio, con participación del Consejo Superior de Investigaciones Científicas (CSIC), prueba que existe gran similitud entre los sistemas excretores de ambos grupos de animales. Según la investigación, las células encargadas de filtrar la sangre en la formación de orina, alojadas en los riñones de vertebrados, son similares a las que realizan una función análoga en invertebrados.
Answer:

Explanation:
I can't really read what you have typed, but the subscripts are the little numbers such as this 2 in H₂O. So using the blue pen, I'm assuming you would circle the little numbers. The coefficients are the numbers in front of the elements so from what I can read, in 2HCl the 2 would be circled in the orange. So in a simple way the subscripts are the tiny numbers that are at the bottom (usually after elements), and the coefficients are normal numbers in front of the whole element.
Hopefully that makes sense! :)
