If the white molecule is water where is the water concentration greatest at first?
If the white molecule is water, the water concentration is greatest in the area where the water molecules are most densely packed. Typically, this would be in a region with a high volume of water, such as a body of water or a solution. Over time, if there is a concentration gradient, water will move from this high-concentration area to areas of lower concentration until equilibrium is reached.

Which mineral has the highest concentration with in seawater?
Sea water with high salinity, low temperatures, and high pressure has the greatest density.
Where is the greatest concentration of water if a red blood corpuscle is placed in sea water?
The greatest concentration of water in this scenario would be inside the red blood corpuscle. Sea water is a hypertonic solution compared to the inside of the cell, meaning it has a higher concentration of solutes. Water would flow out of the cell into the sea water in an attempt to equalize the concentration, causing the cell to shrink.
What type of transport is used to move a molecule from a region of low concentration yo a region of high concentration?
Active transport uses energy to move molecules against their concentration gradient, from an area of low concentration to an area of high concentration. This process requires the use of transport proteins and cellular energy in the form of ATP.
What is the natural tendency of molecules to spread from an are of high concentration to low concentration?
Diffusion. If this happens to a water molecule, it is called osmosis. Moving from lower to higher concentration requires active transport.
In which physical state would a water molecule have the greatest energy?
A water molecule would have the greatest energy in the gas (vapor) state because the molecules are more spread out and have higher kinetic energy compared to the liquid or solid state.
What is the type of molecule that is moving in osmosis?
The molecule that moves during osmosis is water. Water moves across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration in order to equalize the concentration on both sides.
What kind molecule determines the concentration of other substances in the body?
water
Which mineral has the highest concentration with in seawater?
Sea water with high salinity, low temperatures, and high pressure has the greatest density.
What molecule uses osmosis?
Water is the primary molecule that undergoes osmosis. Osmosis is the movement of water molecules across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration in order to equalize the concentrations on both sides of the membrane.

What is called when a molecule moves across a semipermable membrane into a region of a higher concentration?
When a molecule moves to a higher concentration it needs help of a pump. We call this facilitated diffusion. Osmosis only deals with the movement of water.

Which zone has the greatest concentration of plankton in a fresh water lake ecosystem?
Limnetic zone for sure.
Where is the density of electrons greatest in the water molecule?
The density of electrons is greatest around the oxygen atom in a water molecule because oxygen is more electronegative than hydrogen, causing it to attract the shared electrons more strongly. This results in a higher electron density around the oxygen atom.
