List two differences between gram positive and gram negative bacteria.

Properly diagnosing a patient requires distinguishing the correct disorder from other disorders with a similar lab presentation. Which disorder below will present with leukocytosis?

A 60-year-old patient with headaches, pruritus after bathing, and blurred vision is suspected of having polycythemia vera. Which of the following supports this diagnosis?

This lymphocytic disorder occurs primarily in males and presents with massive splenomegaly and absent lymphadenopathy. Laboratory studies show pancytopenia and the occasional presence of abnormal lymphocytes with erratic cytoplasmic protrusions (shown below). Immunophenotypic studies reveal CD19, CD20, CD22, CD25, CD103, and CD11c.

Why might islands be ideal opportunities to study the emergence of new species?

Evolution can be described as:

In a certain population, the frequency of a dominant allele is represented by p = 0.7, and the frequency of the recessive allele is represented by q = 0.3. Given this, what is the frequency of the heterozygous genotype?

When only a very few individuals give rise to a new population in a new area of favorable habitat, the new population might possess different genotype frequencies for a certain trait than the larger population from which it separated. This is called the _________ effect.

A population of bees lives in isolation on a mountaintop. All of these bees display the smooth body phenotype. A strong storm blows several bees from a distinct population up the mountain to the smooth body population. However, these bees have the fuzzy body phenotype. The bees are all of the same species and the body texture phenotype is entirely genetically controlled. The fuzzy bodied bees reproduce with the smooth bodies bees and there are both fuzzy and smooth individuals in the next generation as a result. Select the correct interpretation given this information.
