A foreign exchange rate is the price of the domestic currency stated in terms of another currency.

Sublimation is a process when a solid changes directly into gas instead changing into liquid first. Dry ice is an example of Sublimation process because it doesn't change into liquid CO2 and directly change into gaseous CO2 when heated.

Hence, Dry ice is an example of Sublimation process. 

Osmosis is the process in which water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane. It doen't requires any additional energy to do this work. 

So, Osmosis is a Passive.

Active and passive transport processes are two ways molecules and other materials move in and out of cells and cross intracellular membranes.

1. Active transport is the movement of molecules or ions against a concentration gradient (from an area of lower to higher concentration), which does not ordinarily occur, so enzymes and energy are required.

2. Passive transport is the movement of molecules or ions from an area of higher to lower concentration. Passive transport occurs because of the entropy of the system, so additional energy isn't required for it to occur.

3. Active transport requires energy to proceed, while passive transport does not require the input of extra energy to occur.

Lines are used in art to indicate

a. boundaries between forms.
b. direction and motion.
c. shadows and highlights.
d. spatial depth on flat surfaces.

Tin and Silver are malleable and good conductors of electricity. The other combinations have a non metal in them which are bad conductors.

Since A polymer is a large molecule, or macromolecule, composed of many repeated subunits. Glucose is not a polymer.
