Question

quiz: history and diversity of life 0:22:07 elapsed which foundational concepts in biology were merged in the modern synthesis? a) darwin’s theory of evolution and watson’s and crick’s structure of dna b) darwin’s theory of evolution and mendel’s ideas of heritability c) darwin’s theory of evolution and chargaff’s rules of base pairing d) darwin’s theory of evolution and hershey’s and chase’s proof of dna as genetic material question 9 (5 points) listen plants can reproduce a) constantly. b) only using pollination. c) only by cutting or budding. d) sexually and asexually.

Explanation:

First Question (About Modern Synthesis)

The modern synthesis (evolutionary synthesis) merged Darwin’s theory of evolution by natural selection with Mendel’s principles of genetics (heritability of traits). Watson - Crick’s DNA structure, Chargaff’s base - pairing rules, and Hershey - Chase’s DNA as genetic material work came later and were not part of the modern synthesis.

Second Question (About Plant Reproduction)

Plants have two main reproductive modes. Sexual reproduction involves pollination (for flowering plants, with male and female gametes fusing), and asexual reproduction includes methods like cutting, budding, runners, etc. They don't reproduce constantly (A is wrong), don't only use pollination (B is wrong as asexual methods exist), and don't only use cutting/budding (C is wrong as sexual reproduction is also common).

Answer:

B) Darwin's theory of evolution and Mendel's ideas of heritability
