Chapter 25, Problem 93A

Interpretation Introduction

Interpretation: The question is to find if the third statement given is based on the first two statements.

Concept Introduction: Energy that emanates from a source and moves through space at the speed of light is referred to as radiation. This energy has wave-like properties and is accompanied by an electric field and a magnetic field.

Answer to Problem 93A

The third statement is wrong as radiation kills not only the cancer cells but other cells too.

Explanation of Solution

Given information: Three statements are given:

(1) Radiation kills fast-growing cells.

(2) Cancer cells are fast-growing.

(3) Therefore, radiation kills only cancer cells.

Radiation therapy kills or inhibits the growth of cancer cells by disrupting their DNA when administered in high doses. Cancer cells with irreparable DNA damage either stop multiplying or expire. After the damaged cells die, the body eliminates and destroys them.

Malignant tumors are made of cancerous cells. They often grow faster than benign tumors do. spread, causing damage to the tissues nearby.

Because radiation therapy is most harmful to rapidly reproducing cells, it damages cancer cells more than healthy cells. Preventing the cancer cells from dividing and multiplying, results in cell death in the cancer cells.

Radiation therapy is used to treat a variety of cancers. Sometimes radiation therapy is the only option.

In addition to destroying or delaying the growth of cancer cells, radiation can also harm nearby healthy cells

Conclusion

Hence, the radiation kills not only the cancer cells but other cells too.
