What else can I help you with?
Are polar molecules more likely to be hydrophobic or hydrophilic?
Polar molecules are more likely to be hydrophilic, meaning they are attracted to water and can dissolve in it.
Which molecule is most likely to cause osmosis in the body?
A molecule that is not able to freely pass through the cell membrane is most likely to cause osmosis in the body. For example, large molecules like proteins or ions such as sodium or potassium can cause osmosis by creating an imbalance in solute concentration on either side of the membrane, leading to water movement across the cell membrane.
What happen to water moulcule as heat is applied?
When heat is added to the water, the molecules move faster. When the water reaches the boiling point (100 Degree Celsius), the water molecules at the surface of the water would break apart with the other molecules and escape (evaporate). When they evaporate, the water molecules changes state and becomes water vapour.
What will happen when a membrane sac filled with large molecules of oil is suspended in a beaker of water?
The oil molecules will not mix with the water because they are hydrophobic, causing the oil-filled sac to remain intact. The oil sac will float in the water due to the difference in density between oil and water. Over time, the oil molecules may slowly diffuse out of the sac into the water, depending on the permeability of the membrane.
The diagram represents a cell in water Formulas of molecules that can move freely across the cell membrane are shown Some molecules are located inside the cell and others are in the water outside?
The diagram illustrates a cell membrane with molecules that can freely pass across it. These molecules likely include water, oxygen, and carbon dioxide, which can diffuse across the lipid bilayer. The unequal distribution of molecules inside and outside the cell creates a concentration gradient that drives passive transport.
Are polar molecules more likely to be hydrophobic or hydrophilic?
Polar molecules are more likely to be hydrophilic, meaning they are attracted to water and can dissolve in it.
Why has to happen to the water molecules before they can evaporate?
These molecules gain sufficient energy to escape into atmosphere.
What will happen if you water a plant with water?
It will most likely grow.
What happen to the molecules of the water when it is exposed to sun rays?
The temperature increase and the motion of molecules is accelerated.
What must happen with the water molecules so that they can dissolve compounds?
The water molecules surround the solute (stuff being dissolved) and separate the particles.
What happen when a collection of phospholipid molecules are placed in water?
they form a bilayor
What happen to the molecules of water vapor when the temperature of the gas cools?
the water vapor turns to liquid
Where are hydrophobic interactions most likely to occur?
Hydrophobic interactions are most likely to occur between non-polar molecules or regions of molecules. This can happen in the interior of a protein structure, where non-polar amino acids cluster together away from the surrounding water. Hydrophobic interactions are also important in the binding between certain molecules, such as between a substrate and an enzyme.
What molecules would you expect to dissolve in water polar covalent molecules ionic molecules nonpolar covalent molecules?
Polar covalent molecules are likely to dissolve in water because they have partial positive and negative charges that can interact with water molecules through dipole-dipole interactions. Ionic molecules also dissolve in water as the positive and negative ions are attracted to the polar water molecules. Nonpolar covalent molecules do not dissolve well in water because they lack partial charges that can interact with water molecules.
What happen when you digestive food?
Digestion is the breakdown of large food molecules into small, water-soluble food molecules that can be absorbed.
What type of molecules dissolves in water polar or nonpolar?
Polar molecules dissolve in water. The reason why polar molecules dissolve in water, but not non-polar molecules is because non-polar molecules can't form hydrogen bonds.
What would happen to human blood if put in salt water?
If human blood is put in salt water, the water molecules in the human blood will lead to the lower concentration of water molecules. This process is called diffusion- water molecules going from high concentration to low concentration.
