What makes the head of a phospholipid?
Phosphate molecules.
When placed in an aqueous solution amphipathic molecules will orient themselves with?
When placed in an aqueous solution, amphipathic molecules will orient themselves with their hydrophilic (water-attracting) heads facing the water and their hydrophobic (water-repelling) tails tucked away from the water. This arrangement minimizes the exposure of the hydrophobic regions to the aqueous environment, leading to the formation of structures such as micelles or phospholipid bilayers. This behavior is crucial for the formation of cell membranes and the organization of various biological molecules.
How does cooking happen in a microwave?
When food is placed inside the microwave oven, the microwave released will 'agitate' the water molecules in the food, which causes heat to be produced, which then cooks the food.
When phospholipid molecules are placed in water they form bilayer membranes Describe what you think happens to cause the formation of the bilayer membranes?
The hydrophobic and hydrophilic effect. The nonpolar tails join together in the middle of the bilayer away from water and the polar heads that can tolerate water are on the outside of the bilayer.
What can happen to animal cells when placed in a hypotonic solution explain?
What can happen to animal cells when placed in a hypotonic solution explain
What will happen to a balloon if it is placed in warm water?
The air molecules inside the balloon will heat up and move faster, increasing the pressure inside the balloon. This will cause the balloon to expand and grow in size.
What does Bad debt and placed for collection and skip mean?
Bad debt means debt that is not collectable. Placed for collection means the debt has been sent to a collection agency or department. Skip means the creditor cannot find the debtor and will use different methods to locate the debtor.
What happens to molecules with sufficient energy when a liquid is placed in a closed container?
When a liquid is placed in a closed container, molecules with sufficient energy can escape from the liquid and turn into gas. This process is called evaporation.
What happen to liquid in water?
When a solid is placed in water, it will dissolve if the attractive forces between the water molecules and the solid molecules are stronger than the forces holding the solid molecules together. If the solid does not dissolve, it may remain suspended in the water as a suspension or sink to the bottom as a sediment.
What is polarising?
When a charged body is placed close to a nonconducting substance, the molecules of the substance get polarised. This is called polarisation.
When sugar is placed in water what happens to it?
When sugar is placed in water, it dissolves to form a sugar solution. The sugar molecules break apart and mix with the water molecules, resulting in a homogeneous mixture.
In which phases will the molecules of a substance fill whatever size container they are placed in?
In the gas phase, molecules will evenly fill the size of the container they are placed in. This is because gas molecules have high kinetic energy and are in constant motion, spreading out to fill the available space.
