Answer

1.  Answer: C. 20,000 years

   • Explanation: After 10,000 years (1 half-life), it would be 50,000 atoms; after 20,000 years (2 half-lives), it would be 25,000 atoms; and after 30,000 years (3 half-lives), it would be 12,500 atoms.

2.   Answer: C. About 160 years

   • Explanation: Darwin's "On the Origin of Species" was published in 1859.

3. Answer: B. Hereditary variation

   • Explanation: While Darwin discussed natural selection and survival, he did not have a clear understanding of the mechanisms of heredity (which were later explained by genetics).

4. Answer: C. Presence of homologous structure

   • Explanation: Homologous structures indicate common ancestry, while analogous structures do not.

5.  Answer: B. eternity of life

   • Explanation: The eternity of life concept suggests that life has no beginning or end.

6.  Answer: B. aerobic respiration

   • Explanation: Aerobic respiration evolved after photosynthesis, as oxygen produced by photosynthetic organisms allowed for aerobic respiration to occur.

7.  Answer: C. Jurassic

   • Explanation: The Jurassic period is known for its diversity of dinosaurs and other life forms.

9. Answer: C. use and disuse of body parts

   • Explanation: Lamarck proposed that organisms could develop new traits based on use or disuse of certain body parts.

10 . Answer: A. 50%
