OK, richness you do have to depend on any one
ok so I've done this problem before trust me:
A. bundles of microtubules that separate to opposite poles of a cell - CENTRIOLES
B. prepares protein-packed vesicles for release outside of the cell - VESICLES
C. small storage sacs containing water, food, and waste - VACUOLES
D. rough and smooth organelle that produces protein, steroids, and lipids - ENDOPLASMIC RETICULUM
E. tiny sacs at the end of the ER which contain protein - GOLGI COMPLEX
F. chains of protein fibers that provide support and shape - CYTOSKELETON
G. powerful enzymes used to process cellular activity - LYSOSOMES & PEROXISOMES
H. whip-like structures on cells that are used for movement - FLAGELLA
I. produces and assembles proteins - RIBOSOMES
Oceanic crust<span>tends to be denser and thinner than </span>continental crust<span>, so the denser </span>oceanic crust<span> gets bent and pulled under, or subducted, beneath the lighter and thicker </span>continental crust<span>. This forms what is called a subduction zone. The answer is B.</span>
The circuit has to be closed, so B.
If the circuit was open, the flow of energy wouldn't be able to reach the light bulb.
