Cancer cells are harmfull because they absorb nutrients needed by other cells, block nerve connections and prevent organs from functioning properly (options A, B and C).

Explanation:

Cancer is the result of the loss of the mechanisms that regulate cell multiplication and tissue growth, generating tumors. These tumors can have cells similar to the tissue that originated them or undifferentiated cells, which determines the criterion of malignancy.

A cancerous tumor can affect the organism due to its growth and where it is located, affecting the function of the affected organ, invading other tissues and organs, sequestering the nutrients necessary for their development and function and even causing the interruption of nerve pathways.

Additionally, cancer cells can travel to other locations and cause secondary tumors, called metastases.

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

hope this
