Answer
1235**Explanation:**Here's why these options align with the Theory of Evolution by Natural Selection:* **1. Biochemical variety within species:** Variations in DNA and resulting biochemical differences are essential for natural selection to act upon. This diversity provides the raw material for evolution.* **2. Biochemical similarity within species:** Similarities in biochemistry (DNA, proteins, etc.) demonstrate common ancestry and support the idea that species have evolved from shared ancestors.* **3. Competition for resources:** Limited resources create competition among individuals within a species. Those better adapted to acquire resources are more likely to survive and reproduce.* **5. Environment selects fittest individuals:** The environment doesn't actively "choose," but individuals with traits better suited to their environment are more likely to survive and pass on those traits, thus becoming more prevalent in the population over time. This is the core principle of natural selection.Why the other options are incorrect:* **4. No competition for resources:** This directly contradicts the principle of competition for survival, a key driver of natural selection.* **6. Individuals change to fit the environment:** Evolution doesn't involve individuals consciously changing their traits. Instead, it's the differential survival and reproduction of individuals with pre-existing advantageous traits. (Lamarckism, not Darwinian evolution)* **7. Overproduction and inherited characteristics passed:** While overproduction is important (it leads to competition), the key is that *inherited* characteristics are passed down, not acquired ones.* **8. Overproduction and acquired characteristics passed:** This describes Lamarck's theory of acquired characteristics, which has been largely discredited. Only inherited traits contribute to evolution.
