Certain drugs, known as angiogenesis inhibitors, are effective anti-cancer drugs because they cut off the blood supply to tumors
. Without blood supplying fresh oxygen and nutrients to the cancerous cells, the tumors cannot survive. Given this information, angiogenesis inhibitors will be least effective in treating tumors in A- epithelial tissue
B- connective tissue
C- nerve tisse
D- nervous tissue
Angiogenesis inhibitors can be defined as anti-cancer drugs that inhibit growth and development of newly formed blood vessels around tumors.
These drugs are used in cancer treatment of various types of cancer. This is because, most of the cells receive nutrients and oxygen from blood supply and these drugs cut off the blood supply to tumorous cells.
However, angiogenesis inhibitors would be least effective for treatment of tumors in epithelial tissue as epithelial tissues do to not have blood vessels. These tissue receive nutrients and oxygen from tissue present beneath the epithelial cells.
Transpiration produces a tension or pull on the water in the xylem vessels by the leaves. Water molecules are cohesive so water is pulled through the plant .
