Which option correctly connects three main ideas of this chapter?
Answer and explanation
Correct answer: Heredity, variation and evolution
The chapter focuses on how traits are transmitted, how differences arise, and how populations change over long periods. Heredity explains the transfer of genetic information, variation describes differences among individuals, and evolution is the gradual change that can result when inherited variations are selected across generations. Thus option A presents the three connected ideas. The other choices belong to life processes, mechanics, or chemistry rather than this chapter.
