How did Tinbergen's experiment with digger wasp females demonstrate they used memory to navigate in their local environment?

1. He arranged pinecones and pinecone odor around their actual nest, moved just the pinecones to a fake nest while the female was foraging, and she flew back to the matching arrangement of pinecones, not the odor, indicating a memory of the cones' positioning.

2. He dug branching nests for females and allowed them to explore and lay larvae in the nests. He then moved the larvae in the nest to a new location while the female was foraging, and the female was still able to locate the larvae in the nest demonstrating a memory of how the nest was arranged.

3. He released mother digger wasps near beehives where prey was abundant, recaptured the mothers and brought them to nests with their larvae present, and then re-released them. They found their way back to bees hive demonstrating a memory of its location.

4. He arranged pinecones around their actual nest, rearranged the pinecones while the female was foraging, and she flew back to the same area but could not find her nest, indicating a memory of the cones' positioning and failure to recognize the new cone positioning.

3. sequence

4. interactions of individual amino acid R groups between different chains

5. Individual amino acid R units that are separated from each other by a large distance along the linear sequence of amino acids.

27. How many polypeptide chains are present in the Quaternary structure of a protein?

Waterways mass-produces a special connector unit that it normally sells for $4.00. It sells approximately 38,000 of these units each year. The variable costs for each unit are $2.40. A company in Canada that has been unable to produce enough of a similar connector to meet customer demand would like to buy 15,900 of these units at $2.70 per unit. The production of these units is near full capacity at Waterways, so to accept the offer from the Canadian company would require temporarily adding another shift to its production line. To do this would increase variable manufacturing costs by $0.30 per unit. However, variable selling costs would be reduced by $0.20 a unit.

An irrigation company has asked for a special order of 1,800 of the connectors. To meet this special order, Waterways would not need an additional shift, and the irrigation company is willing to pay $3.20 per unit.

What are the consequences of Waterways agreeing to provide the 15,900 units to the Canadian company? Would this be a wise “special order” to accept?
Should Waterways accept the special order from the irrigation company?
What would be the consequences of accepting both special orders?

Description:

Shenya Jones, 34-year-old female, arrives at the office with swelling and a red pustule on her face. She states that the problem started 2 days ago as a small pimple near her nose. It became irritated, and then extremely swollen and painful overnight. This morning, she noticed yellow drainage at the lesion site and the swelling has increased. The area of drainage is approximately 1 cm in diameter. Her upper lip, side of the face, and nose are all swollen. The examination and treatment areas need to be prepared before you bring her to the back office.

Discussion Questions:

1. What needs to be done before Shenya is brought back into the exam room?

2. Shenya is diagnosed with community-acquired MRSA (a highly contagious microorganism). What measures should you take to ensure there is no transfer of infection?

3. After Shenya’s examination, you will need to use an ultrasonic cleaner for sanitization. Describe how you would proceed and what source you would use if you had questions about the cleaner you are using.
