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.
Coastal mountains force cool, moist air from oceans to rise as it moves toward land. Clouds form, and precipitation falls on the <u>windward</u> side of the mountain. On the <u>leeward</u> side of the mountain, very little precipitation falls.
DNA and RNA are both made up of monomers called nucleotides. They also both have three nitrogenous bases: Adenine, Cytosine, Guanine.
Answer:
