Answer:
The Rf values indicate how soluble the particular pigment is in the solvent by how high the pigment moves on the paper.
Explanation:
The Rf values indicate how soluble the particular pigment is in the solvent by how high the pigment moves on the paper. Small Rf values tend to indicate larger, less soluble pigments while the highly soluble pigments have an Rf value near to one.

Answer:
antibodies being produced to fight off a pathogen inside the body
Explanation:
Specific immune responses, also known as the adaptive immune system are ways the body fights against pathogens. The body is able to identify cells that are unique to it. When pathogens bearing an unknown identity enter the body, antibodies are released to attack the antigens on the surface of these pathogens.
The body usually develops this immunity after a previous attack by the pathogen. Lymphocytes known as the B and T cells are released by the immune system t engulf the pathogens.
The blue visible light waves have a shorter wavelength than the red visible light waves. Since both the waves travel at the speed of light, which is a constant for a particular medium, their frequencies will be inversely related to their wavelength. This is given by the formula: speed = wavelength x frequency. Thus blue visible light will have a higher frequency than the red visible light.
