The body contains about a trillion cells
Answer:
DNA stores that info
Explanation:
In eukaryotic cells (ex. plants and animals) the DNA is found in the nucleus of the cell. Structures called ribosomes build proteins (this process is called translation).
A way we can reduce disadvantages of human made materials is simply by finding new uses for them such as when plastic is molded and used for a container of a liquid.
The right answer is <span>A) semi-permeable membrane
<span>A semi-permeable membrane is a membrane permeable to a liquid (solvent) and impermeable (or poorly permeable) to substances dissolved in the liquid (solute).
</span>The tubule of a kidney consists of a semi-permeable membrane and has also specific transporters which allow absorption and reabsorption. These "tools" allows some substances like ions to be absorbed/reabsorbed (by the transporters), without any changes in the concentration of the other substances (because both the membrane and the transporters stopped them).</span>
