Chapter 16, Problem 13PS

Summary Introduction

To explain: The reason for the quick observation in the genetic effects of radiation on mosses than on other types of plants. After nuclear accident, imagine a scientist conducting test by using the potted moss plants as the experimental organisms. Also design an experiment to test the hypothesis that the frequency of mutation decreases with the organism’s distance from the source of radiation.

Introduction: As given in the question, the accident scatters the radioactive fallout for about the hundreds of miles which show the biological effects of radiation. These radiations damage the organisms by mutation. The mutation may be in the DNA or chromosomes that will directly affect the genetics of the organism and can cause hereditary diseases.
