During the process of oncogenic transformation, cells often lose the
function of a specific family of adhesion receptors known as Cadherins.
The resulting loss of adhesion is accompanied by changes in cell
morphology. Based upon this, cadherins could be classified as:
adherin junctions
An avascular tissue with a large amount of ground substance and very
few cells would most likely be classified as:
loose connective tissue
, PNB 2264 Human Physiology and Anatomy
The cells that make up lymphatic vessels (which transport fat and large
bulky molecules) display fewer physical connections between themselves
than blood vessels. This means that lymphatic vessels favor which type of
transport?
paracellular

a. energy consumption
b. reproduction
c. responding to external stimuli
