Name three examples of courtship behaviors
Visual displays, courtship dances, and acoustic vocalizations
Explain how sexual reproduction occurs in flowering plants. MUST use the terms (pollen, anther, stigma, ovary, fruit/seed, pollinator, fertilization) (one point per term used)
Sexual reproduction in flowering plants begins when a pollinator transfers male pollen from an anther to a sticky female stigma. The pollen grows a tube down to the ovary, where fertilization occurs, merging male and female gametes to form a seed. Finally, the ovule develops into a seed, and the ovary matures into a fruit.
Variations in traits among individual members of a species are primarily due to what?
Recombination of traits due to sexual reproduction and genetic mutations
What is natural selection?
The process by which organisms with variations that help them survive in their environment live longer and reproduce more.
What does "survival of the fittest" refer to in the context of natural selection?
Survival of organisms that are best adapted to their current environment.
What are adaptations in organisms?
Inherited traits that help organisms survive in their environment.
Which of the following is NOT a major type of adaptation?
Temporary adaptations
How do structural adaptations help organisms survive?
By changing physical features to fit better into their environment.
Which of the following is a structural adaptation?
Having a shark beak to open tough fruits.
Which of the following is a behavioral adaptation?
Learning where the best food on an island is, and visiting that spot every day
Which of the following is a physiological adaptation?

How do behavioral adaptations help organisms survive?
By adjusting to their environment and doing things that help them stay alive.
How do physiological adaptations help organisms survive?
By changing body chemistry and internal processes
