<u>Answer:</u>
<em>The true statement concerning complex multi-cellular organism is Bulk transport systems move substances faster than simple diffusion.</em>
<u>Explanation:</u>
<em>Bulk transport</em> is the mechanism that is used by the cells to transport the large quantity of small and tiny molecules and particles. Bulk transport works on the <em>mechanism of pressure gradient and single diffusion</em> is based on the concentration gradient.
The<em> transportation on single diffusion</em> is due to random motion of molecules but in bulk transport the solute and water is moved <em>together and in a faster pace. </em>
Answer:
Adding a lake near any town will most likely increase rainfall because of the added water, and water vapor levels will also increase. Because of the excess water in the environment, more water will be found in the surrounding atmosphere (the same reason precipitation will increase in the area.)
They exhibit considerable molecular complexity and diversity
