Choose one of the 3 systems (circulatory, respiratory, digestive )

Frog, earth worm, and squid

Describe at least two similarities between all 3 Also describe at least 2 differences

someone please help
would be extremely appreciated :) ​

Explanation:

1. All three digestive systems take up majority space inside their bodies

2. All three of the animals food prey begin through the mouth and end through the anus

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.

it should be briana that has it to me
