Answer:
The statement is False
Explanation:
Osmotic pressure is created by the movement of water across the semi-permeable membrane. In osmosis water moves from an area which is having low solute concentration to the area which is having high solute concentration.
So in osmosis, the movement of water takes place not molecules. This pressure is caused by differences in solute concentration across the plasma membrane and water moves to high concentration to equalize the pressure. Therefore the statement is wrong.
The <span>correct answer is eutrophication. Eutrophication
is the enrichment of bodies of water with nutrients that encourage plants
growth. It is also called hypertrophication. Eutrophication is caused by human’s
activity in the bodies of water. However, eutrophication is also a natural
process especially in lakes.</span>

Hello!
A polar molecule is where one of the atoms in a molecule has a slight positive charge, and another has a slight negative charge, due to the unequal sharing of electrons.
Water is one of these molecules - the electrons spend more time around the oxygen atom in the center, and less around the hydrogens, so the hydrogen atoms have a slight positive charge, and the oxygen a slight negative.
Therefore, your answer is B, water has a slight negative and a slight positive charge at opposite poles.
Hope this helps!
Answer:
As quantitative data collection methods are often based on mathematical calculations, the data obtained that way is usually seen as more objective and reliable than qualitative. Some of the most common quantitative data collection techniques include surveys and questionnaires (with closed-ended questions).
