Liver tissue is a combination of many types of cells. in addition to other tissues, it contains connective tissue and epithelial tissue. which two sentences correctly identify the roles of these tissues? connective tissue supports the framework of the liver, and epithelial tissue protects the liver. connective tissue to send impulses to the brain, and epithelial tissue in contraction and relaxation. connective tissue with contraction and relaxation, and epithelial tissue supports the framework of the liver. connective tissue forms the lining of the liver, and epithelial tissue to send impulses to the brain. connective tissue holds the liver in place during movement, and epithelial tissue forms the lining of the liver. nextreset

The right answers are: A and E (the first one and the last one).

Tissue cells is defined as a set of cells of the same constitution and exerting a same function. Connective tissues (or connective tissue) are tissues whose main function is to provide support and protect other body tissues.

Epithelia are tissues consisting of cells closely juxtaposed (or joined) without interposition of fiber or fundamental substance (in light microscopy, which distinguishes them from connective tissue).

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
