Oxygen is produced in the light stage of photosynthesis at Photosystem 2 and results from the splitting of water. Chlorophyll does not absorb green light so in green light there will be less water split and so less oxygen is produced.so thats how we know the reason why a leaf is the color that it is. basically it is because of chlorophyll.
Hope this helps.
1. The distilled water has a higher concentration of water molecules.
Distilled water only contained water molecules, nothing else is dissolved in it. It has the highest water concentration no matter what substances.
2. The red blood cells has less water potential.
Water potential is the tendency of the water molecules to move from one region to another. Due to the rule of osmosis, water molecule is more likely to move from the distill water to the cell, from a region of higher water concentration to a region of lower water concentration.
Therefore, red blood cell has less water potential.
3. Distilled water is a hypotonic solution.
When the solution causes the water to flow away to other regions, they're said to be hypotonic. There water potential is higher than the other side. Therefore, the answer is distilled water.
<span>that really just depends on what type of cells we are talking about here. :) Bacterial cells can send a huge array of signals, like in pathogenic bacteria at the time of colonization, they send out signals to neighboring cells in the form of chemical substances to produce virulence factors like toxins. In short, gene regulation changes are brought about. This is just one example and is one of the effects of a process called Quorum Sensing. </span>
