Answer:
This question appears incomplete
Explanation:
This question appears incomplete. However, <u>the cell organelle involved in transportation of molecules in the cell is the </u><u>cell membrane</u>. This cell membrane can be said to be cause of several forms of transportation in and out of the cell - this is because the membrane is a selective barrier. While some substances/molecules move through diffusion by moving with the concentration gradient (as in the case of passive transport, others move against the concentration gradient requiring energy to cause the transportation (as in the case of active transport).
Answer: Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins.
Explanation:
Answer:
The conveyor belt moves at much slower speeds (a few centimeters per second) than wind-driven or tidal currents (tens to hundreds of centimeters per second). It is estimated that any given cubic meter of water takes about 1,000 years to complete the journey along the global conveyor belt
