Describe the honeybee mating system. Which bees secrete alarm pheromone, and what does it do? What is the purpose of queen mandibular pheromone?

Drones: females, gather food; Queen: male, protects hive; Workers: males, mate with queen.

Drones: females, protect hive; Queen: female, mate with drones; Workers: males, lay eggs.

Drones: males, protect hive; Queen: male, lays eggs; Workers: females, search for new hive locations.

Drones: men, sit in hive and inseminate the queenQueen: only fertile femaleWorkers: females; maintain hive and watch bee offspring alarm pheromone-release by drones when hive is under attack, workers respond (only ones with stingers)queen mandibular pheromone-sterilizes workers

Sample Question
Keep in mind the concepts of osmolarity and tonicity. There will be another osmolarity problem on the final.

A) Osmolarity is the measure of resistance of a solution to flow freely due to the presence of solutes.

C) Osmolarity and tonicity are terms that can be used interchangeably to describe the concentration of solutes in a solution.

B) Tonicity is a measure of the color intensity of a solution based on the concentration of solutes.

Osmolarity is an easily measurable characteristic, by e.g. freezing point depression. In simple terms it is the total concentration of solutes (including ions) in a solution, and this does not depend on whether the solutes can cross cell membranes or not. Tonicity relates to the osmotic GRADIENT due to solutes that affects a semi-permeable membrane ( i.e. a membrane that is permeable to water); ONLY solutes that do not cross the membrane contribute to this effect.
