A nurse is preparing to administer 5% dextrose in 0.45% sodium chloride 1000 mL IV to infuse over 12 hr. The nurse should set the IV pump to deliver how many mL/hr? (Enter the number only in the blank. Round to the whole number.)

Read each question carefully. There is only one correct answer unless the stem of the question includes directions that state otherwise. There are 80 items on the exam. You have 120 minutes to complete the exam. There is no backtracking to complete a skipped question or to change an answer.

A eukaryotic organism is found to produce 30,000 different proteins, but only has 15,000 different genes. What best explains this?

Suppose that in humans, genes A and B are located close to each other on the same chromosome.  An individual has the genotype AaBb. Alleles A and B are on one chromosome and alleles a and b are on the other.  We would expect that when this individual passes on alleles to their offspring, ____________.

A BIOL 115 student is tutoring middle-school students in biology. One of the middle-school students says, “In a diploid organism, meiosis will always produce haploid gametes.”  Is the middle-school student correct?

A genotype can produce a given phenotype. What cellular processes are involved in producing an individual’s phenotype from its genotype? 

Proteins carry out a wide variety of cellular functions, including serving as enzymes, forming structural components of cells, transporting things within a cell, facilitating cell-cell recognition, receiving signals, and transporting things across membranes. Because of this, protein synthesis is very important in cells. What structure in a cell is responsible for synthesizing the primary structure of a protein?

If a pseudo-random number generator  (PRNG) has backward secrecy and if the additional entropy source is not compromised and changed continuously,  the PRNG should be completely predictable if the seed is known.

In Schnorr identification protocol, Peggy must commit to her random value k so that she can change it later. After receiving Peggy’s commitment, Victor introduces some of his own randomness in the protocol. 

A nonuniformly random value should be used to seed a PRNG that can quickly produce random numbers.
