The groups of small cells better than one large cell at moving material in and out because they have a greater surface-to-volume ratio.
<u>Option: A</u>
<u>Explanation:</u>
This happened so as these smaller cells, unlike bigger cells, can quickly and willingly enter and move through the membranes of other cell membranes and permeable coverings. For these smaller and mini cells, it is also important to penetrate and move effectively, distribute and transport products and materials such as nutrients, oxygen and waste across the body without requiring enough energy and saving less space. They are cheaper, more effective and use less room for simple reasons, and most notably deplete less resources.
Inside our body, millions of nephrons in the kidney filter wastes in 2 steps. Each nephron has a glomerulus and a tubule. Waste filtering undergoes 2 steps:
First, fluid and waste pass through the glomerulus but, proteins, blood cells, and other large molecules are prevented from passing through. Second, the filtered fluid passes through the tubule wherein the filtered wastes are removed; minerals are sent back to the body, and the remaining output becomes urine.

Explanation:
Protists are very diverse group of organism, it contains all the organisms that does not fits into other kingdom. All of the protists are not heterotrophs some of them are autotrophs. They reproduce sexually but some of them reproduce asexually. Example: amoeba: binary fission. Some of the protists are multicellular. Some of them are unicellular too.
