Question

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 which kind of tissue?

a) epithelial tissue
b) connective tissue
c) nerve tissue
d) muscle tissue

Answer 1

a. epithelial tissue or nerve tissue

Answer 2

The answer is A, you can't cut the blood supply because the epithelial tissue is on blood vessels and organs, so you can't cut it.
