Only about 3 percent of the worlds water is fresh, and even less than that is usable, because most of it is locked up in glaciers or in permanent snow fields.
The correct answer is D.
For this question I'm not too sure what you're asking because cells that transport water are basically xylem cells and these cells are hollow with nothing in them, and they transport water against gravity because of transpiration pull, capillary action and root pressure.
The cells that I know of with many mitochondria for transport would be the phloem so that the mitochondria can carry out cellular respiration to release energy for the translocation of sucrose.
Answer:
The length of the two wires
Explanation:
A control variable is what you keep the same through the whole experiment so therefore it could be both length and diameter
Answer:
