measurement used to determine the amount of a substance being used. This
particular measurement is usually used during chemistry experiments as
it determines how many representative particles there are in any one
amount of substance.

Answer No 1:
A concentration gradient can be described as a phenomenon by which molecules travels from an area which is highly concentrated to an area which has low concentrations of that molecule.
Answer No 2:
A molecule is said to be diffusing down a concentration gradient when molecule acquire the phenomenon of concentration gradient i.e move from higher concentration to lower concentration. This mechanism is also termed as passive transport. Active transport is the opposite of passive transport. In active transport, molecules move against the concentration gradient i.e from an area of lower concentration to an area of higher concentration.
The lymph vessel flows from the tissue to the lymph nodes, flow to the largest lymphatic vessel in the thorax called thoracic duct, then drain to the subclavian vein.
The lymphatic vessel is a thin tubular organ made of the endothelial cell. It has a valve like the vein to prevent backflow of lymph. Lymphatic vessel delivers the lymph through the body and has a role in the immune system.
