AP Biology Flashcards: Smell Integration

Questions and Answers

Which of the following accurately describes how the dog's brain integrates information for smell?

Receptors originating in the nose send action potentials to the motor regions of the brain.

Chemoreceptor cells in the nasal cavity send impulses to the appropriate area of the brain. (correct)

Chemoreceptors on epithelial cells of the tongue send hormones to the appropriate area of the brain.

Chemoreceptors in the brain send impulses for smell in the nasal cavity.

Which of the following types of data would be most useful for the scientists to collect at regular intervals on a designated test plot of rose plants?

Amount of sunlight (hours/day)

Density of rose pollen produced (g/m²) (correct)

Amount of pollen produced by each flower (g/flower)

Mean temperature (°C)

If ATP breakdown (hydrolysis) is inhibited, which of the following types of movement across cell membranes is also inhibited?

Facilitated diffusion of a permeable substance

Movement of water through aquaporins

Passage of a solute against its concentration gradient (correct)

Movement of oxygen into a cell

Study Notes

Dog's Sense of Smell

Chemoreceptor cells in the nasal cavity transmit impulses to specific areas of the brain to process smell.

Thrips Population Study

Increased thrips populations in spring, decreased in summer suggests food abundance impacts population size.
Useful data to collect: Density of rose pollen produced (g/m²) for understanding food availability.

ATP and Cell Movement

Inhibition of ATP hydrolysis disrupts movement of solutes against their concentration gradient.

Marine Habitat Disruption

Undersea landslides can reduce marine population sizes.
Surviving organisms post-landslide likely show different allelic frequencies compared to pre-landslide population.

Calvin Cycle Understanding

Key question about the Calvin Cycle pertains to how ATP is utilized in forming 3-carbon carbohydrates.

Blood pH Regulation Post-Exercise

Elevated H+ levels lead to lower blood pH; normal levels restore via increased breathing rate, lowering blood CO2 and H+ concentration.

Community Diversity and Nonnative Species

High species diversity in a community correlates with increased resilience against destabilization by nonnative species.

Beetle Population Conditions

Maximum observed number of beetles occurs in T.castaneum with a parasite after 100 days.

Effects of Parasites on Tribolium Populations

T.castaneum is adversely affected by the parasite, unlike T.confusum which shows different responses.
