Middle School Life Science Flashcards: Traits Affect Populations

Study Traits Affect Populations in Middle School Life Science with focused flashcards that help you recognize the idea, recall the key rule, and apply it in practice-style prompts.

QUESTION

Identify the most likely population outcome when a new predator appears and one color morph is better camouflaged.

ANSWER

The better-camouflaged morph increases in frequency over generations. Natural selection favors traits that reduce predation risk.

Practice questions

1 of 50Practice questions for this set
A population of flowering plants has trait variation in flower tube length: short or long. A pollinator shift occurs: over 6 years, long-tongued moths become more common than short-tongued bees. Seed counts show that in years with more moths, long-tube plants produce more seeds than short-tube plants. Trait frequencies change from Year 0 to Year 6: short-tube 70% to 40%, long-tube 30% to 60%. Traits can affect population outcomes. Which claim about traits is incorrect based on the evidence?
