Vesnalui [34]4 years ago

Osmosis : a diffusion of a solvent (most of the time water molecules) through a membrane that is semipermeable in a area that is low solute concentration to an area of high solute concentration  

Diffusion : A net passive motion of particles (atoms, ions, or molecules) from a section which they are higher in concentration compared to areas in lower concentration.  It goes on until the concentration is all the same.

Active Transport : The motion  of ions or molecules along a cell membrane in the direction opposite of the diffusion or  from an area of lower concentration to one of higher concentration. Active transport needs the assistance of a certain protein known as a carrier protein which uses energy supplied by ATP.

rewona [7]

.......is secreted into the bloodstream, whereas _____ is secreted into mucus such as gastrointestinal fluid, colostrum, saliva, tears, and sweat:

a. Monomeric IgM; pentameris IgM

b. Monomeric IgA; dimeric IgA

c. Monomeric IgA; dimeric IgM

d. Dimeric IgA; monomeric IgA

Answer:

b. Monomeric IgA; dimeric IgA

Explanation:

IgA is a class of antibodies that are found mainly in body secretions. In sweat, tears, saliva, mucus, breast milk, and gastrointestinal secretions, IgA is secreted as a monomeric antibody. Smaller quantities of this class of antibodies are also present in blood and lymph. However, IgA is present in a dimeric form in the bloodstream. It makes up 10–15% of all antibodies in the blood. The main function of this class of antibodies is to give localized protection of mucous membranes against bacteria and viruses.
