The many volcanoes located along the edge of the pacific ocean make up the ring of fire. how does subduction play a role in the volcanic activity in the ring of fire?
a)most of the plate boundaries involve one plate sliding underneath another.
b)most of the plate boundaries involve plates spreading apart, forming new ocean floor.
c)most of the plates are stationary, capable only of forming hot spots.
d)most of the plates rub horizontally against each other.

A. Most of the plate boundaries involve one plate sliding underneath another.

Along the Ring of Fire, subduction causes one plate to slide beneath another. The bottom plate plunges into the mantle. Once in the mantle, the plate melts and can then rise up as a volcano.

videntify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
