A. It depends on where it is moving, not the substance
OB. This is describing diffusion
OC. Does not require energy, it is passive transport through a semi-permeable membrane
 
        
             
        
        
        
<span>The answer should be: D)	water supply
</span>Water is a perishable resource and its supply will limit how much population that an area could hold. <span>With a bigger population, the competition for water will be higher which make water shortage more likely. Others density-dependent limiting factor than competition would be disease, parasitism, and predation.

The correct answer for the question that is being presented above is this one: "Synthesized." A scientist isolates a gene from a human cell that codes for a specific protein. The gene is inserted into a bacterial plasmid in order to mass produce the protein for medical purposes. The next step in mass production of the protein would be synthesized of the bacterium containing the modified plasmid.<span>
