Siroma, you've completely misunderstood the question. The grade is important, but it was the subject area that was questioned. Cell Biology is not worthless by any stretch of the imagination. You could always have a degree in Art or Media Studies. See how far that gets you. Your options are much li...

Generally, yes. To get some salary you have to get minimum 2nd degree in biology.

Monosacharide transporters in small intestine

Hi! Which monosachharides can be transported to blood from small intestine? Glucose, Fructose, Mannose, Fucose are ones known to me. What about allose, atrose, other aldohexoses? What about ketohexoses, like psicose, sorbose? What about pentoses, tetroses, trioses? Also, "No cell surface transp...

1. You have somehow to channel polar hydrophiles through hydrophobic membrane. If it's down electrochemical gradient of food particles, simple pores can be used. Against the potential you have active primary or secondary transport ( pumps or simports/antiports respectively ). 2. You have to invest e...

One example of mosaics is human females. Randomly, one of two X/X chromosomes is deactivated {for gene balancing (males have only one X chromosome )}. Because one X comes from mother and one from father, they may have different alleles. Thus, a clone of tissue produced from ancestral cell with, say,...
