The answer is false, liquid molecules continue to move even after the concentration is uniform.
Diffusion happens because there’s a concentration gradient between the dye and the water, therefore dye molecules moves to the water area. But note that this is only the net movement of the molecules, which means, even if more molecules are moving towards water, there are still some dye molecules that are moving in the opposite direction.
So, after the concentration is equal, the motion of the dye molecules does not stop, they still move in random directions, but there’s no net movement instead, as there’s no concentration gradient. Remember molecules are always moving in all directions , it just depends on whether there’s a net movement or not. If there’s no net movement, the amount of molecules moving to each and every direction is always equal.
The removal of the cell membrane.
The membrane regulates homeostasis by letting "stuff" (general term) in and out of the cell.
Answer:
Explanation:
Given that,
The mass of a sample, m = 16.7 grams
Volume of the sample, V = 4.4 cm³
We need to find the density of the metal sample.
Density = mass/volume
Substituting all the values,
So, the density of the metal sample is 
.
Each month's fertile period is different for every woman, but on average the days between the 10th and 17th day of the cycle are the most fertile ones. More specifically, this period refers to days 12 to 16 before the beginning of the next period. This timeframe refers to the ovulation, the process that includes the release of an egg from an ovary.
