Answer:
When starfish were removed from their environment, the species richness of that area went down. This was because the starfish ate the mussels, and when the starfish were removed, the mussels became abundant and preyed on many of the other species.
This experiment showed that the starfish were a keystone species. A keystone species is a species that has a low biomass but a large impact on the community they are living in.
Answer:
I believe D would be the answer
Explanation:
As in the first part the pseudo podium is engulfing the particle which is more similar to taking food and the next part in the phagosome the particle is engulfed and further the enzymes would be released which would digest the particle hence similar to digestion
The answer to this is Quaternary.
Vesicles are used to ship materials around, into, and out of the cell. Cell membranes can pinch off in places to form vesicles, as can lysosome membranes and golgi membranes. Because mitochondria and chloroplasts are practically tiny cells within cells, I wouldn't be surprised if they had their own vesicles. If you're asking literally which organelles have vesicles inside them, I'd say the mitochondria and chloroplasts, possibly Golgi (depends on your instructor), but the cell membrane, lysosomes, and golgi can definitely make vesicles. The rough ER uses vesicles but I wouldn't consider the vesicles a part of the ER.
