Why Should the Period-Luminosity Relationship Be Different for Type I

question 50

Multiple Choice

Why should the period-luminosity relationship be different for Type I Cepheids and Type II Cepheids?

• A) Type II Cepheids are dwarf stars and thus much less luminous than Type II giants.
• B) Type I Cepheids are metal-rich and thus have more heavy elements in their atmospheres.
• C) Type II Cepheids are metal-rich and thus have more heavy elements in their atmospheres.
• D) Type I Cepheids get their energy primarily from hydrogen fusion while Type II Cepheids get their energy primarily from helium fusion.

Interpret the significance of molecular clock analysis and geological dating techniques in studying speciation and evolutionary history.

Explore the role of environmental factors and pollinators in the diversification of species.

Evaluate the evidence for various modes of speciation (allopatric, sympatric) and understand their impacts on species diversity.

Recognize the implications of genetic divergence and the Dobzhansky-Muller model in the speciation process.
