We know, 1 g = 1000 mg
so, 250 g = 250,000 mg
Also, 330 g = 330,000 mg
So, Difference = 330,000 - 250,000 = 80000
In short, Your Answer would be 80,000
Hope this helps!

Exoskeleton is a evolutionary innovation. This is operated by muscles attached to it and acts as an armor. Other than support this is an adaptive mechanism to provide protection against predators. In vertebrates, it is considered as the dermal bone that developed via membranous ossification. Fishes retained their exoskeleton in the form of their scales. However, in some organisms terrestrial evolution allows the loss of exoskeleton and formed a more mobile endoskeleton,
Answer:
c. sound
Explanation:
Matter is formally defined as being any substance that has any amount of mass and takes up space by having volume. Dirt, Humans, and Water all have a different level of mass and take up a different level of space.
