Cells are the basic building blocks of tissues. All cells experience changes with aging. They become larger and are less able to divide and multiply. Among other changes, there is an increase in pigments and fatty substances<span> inside the cell (lipids).</span>
<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>
