Question

why are cancer cells harmful? choose three correct answers.
□ they prevent organs from functioning properly.
□ they absorb nutrients needed by other cells.
□ they block nerve connections.
□ they stop cell growth and division.

Explanation:

• "They prevent organs from functioning properly": Cancer cells can invade and disrupt normal organ tissue, impairing organ function.
• "They absorb nutrients needed by other cells": Cancer cells grow uncontrollably and compete with healthy cells for nutrients.
• "They block nerve connections": As tumors grow, they can compress or invade nerve tissues, disrupting nerve connections. The option "They stop cell growth and division" is incorrect because cancer cells actually have uncontrolled growth and division.

Answer:

A. They prevent organs from functioning properly, B. They absorb nutrients needed by other cells, C. They block nerve connections
