What is the scientific term for a random change in DNA that can introduce new genetic variation?
Mutation.
What is the process called when humans selectively breed plants or animals for desirable characteristics?
Artificial selection.
What is the scientific term for the variety of life in an ecosystem or across the biosphere?
Biodiversity.

What are the three main types of adaptations discussed in class?
Structural, behavioral, and physiological.

What is the term for changes in gene frequencies caused by random chance, especially in small populations?
Genetic drift.
Male birds with brighter feathers attract more mates and reproduce more successfully. What specific type of selection does this demonstrate?
Sexual selection.
Bees obtain nectar from flowers, while flowers benefit from pollination by bees. What specific type of symbiotic relationship does this represent?
Mutualism.

A population of birds experiences approximately the same mortality rate at every stage of life. Which type of survivorship curve does this represent?
Type II survivorship.
A desert lizard develops the ability to produce highly concentrated urine, allowing it to conserve water. Identify the specific type of adaptation.
Physiological adaptation.
A few birds from a large mainland population fly to an isolated island and establish a new population. Their descendants have different gene frequencies than the mainland population due to the characteristics of the original colonizers. Identify this evolutionary mechanism.
Founder effect.
Two unrelated species of aquatic animals develop similar streamlined body shapes because they live in similar environments. What pattern of evolution does this demonstrate?
Convergent evolution.
Two wolves from the same pack compete for access to the same mate. What specific scientific term describes this type of competition?
Intraspecific competition.
A bacterial population grows rapidly without significant limiting factors. Which population growth pattern is represented by a J-shaped curve?
Exponential growth.

A population of fish can survive in water temperatures between 10°C and 30°C. However, most fish are found between 18°C and 22°C. What is the scientific term for the temperature range of 18–22°C?
Optimal range.

A wildfire randomly kills 90% of a rabbit population. The remaining rabbits reproduce, but the new population has much less genetic variation than before. Identify the specific evolutionary mechanism.
Bottleneck effect.

A single ancestral species becomes separated into two populations. Over many generations, the populations develop different characteristics and eventually become distinct species. What pattern of evolution does this demonstrate?
Divergent evolution.

Two bird species live in the same tree. One species eats insects from the upper branches, while the other eats insects near the trunk. Identify the ecological strategy that reduces competition between them.
Resource partitioning.
A contagious disease spreads more quickly as a deer population becomes crowded. Is this a density-dependent or density-independent environmental resistance factor? Explain why.
Density-dependent. The disease spreads more easily as population density increases.
(Drawing) Draw a bell-shaped tolerance range graph and correctly label three types of zones, including the zones on both ends of the graph.
A bell-shaped curve with an optimal range in the center, zones of physiological stress on either side, and zones of intolerance at the two extremes.
Two populations lose genetic diversity. Population A experiences a sudden flood, while Population B is established by five individuals that migrate to a new island. Identify the specific evolutionary mechanism in each and explain the difference.
A = Bottleneck effect; B = Founder effect. The bottleneck results from a major reduction in an existing population, while the founder effect occurs when a small group establishes a new population.

The wings of bats and birds perform similar functions, but their wings evolved independently as flight structures. What is the scientific term for structures that perform similar functions but evolved independently?
Analogous structures.
Two species of lizards feed on the same insects, occupy identical habitats, and reproduce in the same areas. Neither species changes its resource use. According to the competitive exclusion principle, what long-term outcome is expected?
One species will eventually outcompete and locally exclude the other because two species cannot indefinitely occupy the exact same niche under stable conditions.

A species produces hundreds of offspring, provides almost no parental care, and experiences very high mortality early in life. Identify its reproductive strategy and survivorship curve.
r-selected reproductive strategy and Type III survivorship.
