What are the fundamental processes studied in BIO 1? correct
answers
Adaptive evolution, speciation and extinction, population
growth and regulation, species coexistence, and maintenance
of biodiversity.
What is the primary focus of ecology? correct answers
The scientific study of interactions among organisms and
between organisms and their environment.
What is evolution? correct answers
Changes in heritable characteristics in populations over
successive generations.
What is adaptation in the context of evolution? correct answers
The process of evolution by natural selection, resulting in
organisms that are well-suited to their environment.

What is the difference between macro-evolution and micro-
evolution? correct answers
Macro-evolution refers to large-scale evolutionary changes,
while micro-evolution refers to small-scale changes within
populations.
What is the Hardy-Weinberg principle used for? correct answers
To determine which evolutionary forces are acting on a
population.
What factors influence biodiversity across space and time?
correct answers
Climate, environmental stressors, and trade-offs.
What are the levels of organization in ecology? correct answers
Individual, population, species, community, and ecosystem.
What is the significance of biogeochemical cycles? correct
answers
They involve the biotic and abiotic processes that recycle
nutrients in ecosystems.
