Two students run laps around the field during P. E. at school. In science class, the two students are discussing which body systems interact to carry out the process of movement. Which student provides the best argument for two systems working together to help them run around the field? (AKS 2b)

The answer is planting vegetation : )

Ican’t exactly answer this, but i can try to give a bit more info here.
astronomers are able to calculate a star’s life expectancy depending on its mass. (a larger star burns more gas, therefore having a shorter life span).
so astronomers can definitely predict the death of stars and the times they will die.
i hope this was in some way : )
