What is the worst-case runtime complexity of the remove() operation in a binary search tree (NOT necessarily balanced), given problem size N is the total number of elements stored in the tree?

The dequeue() operation on a QueueADT can be implemented in constant time O(1) using ___________________________. (Select all which apply.)

Mrs. Jackson has Type A blood but she is not sure if she is homozygous or heterozygous. Mr. Jackson is completely unsure of his blood type. Their children have the following blood types: Phillip has Type O blood, Tom & Blake have type A blood, Lydia has type B blood and Percy has type AB blood. Use A, B, and O to symbolize the alleles. What is Mrs. Jackson’s genotype? What is Mr. Jackson’s genotype?

Suppose you are a biologist trying to discover how DNA copies itself. You grow cells in a culture that contains a special isotope of nitrogen, N-15, which will become part of any new DNA the cell makes. After one generation, you analyze the DNA and find that all the DNA has N-15. You then take those cells and grow them for another generation in a culture with the normal isotope of nitrogen, N-1. You know half of the DNA has only N-15 and half has only N-14. What can you infer from this information about how DNA replicates? Explain your reasoning.  

What is a negative externality? Give an example of something with a negative externality and what that negative externality is. Does the externality arise from under- or over-production by the market?  (2pts.)  Using your example of a negative externality, explain why a tax or government regulation might help the economy to reach an efficient production point. (2pts) What is a positive externality? Give an example of something with a positive externality and what that positive externality is. Does the externality arise from under- or over-production by the market?  (2pts.)  Using your example of a positive externality, explain why a government subsidy might help the economy to reach an efficient production point.
