Which of the following is the correct sequence of events under the influence of natural selection with genetic variation in the population? 1. Well-adapted individuals leave more offspring than do poorly adapted individuals. 2. A change occurs in the environment. 3. Genetic frequencies within the population change. 4. Poorly adapted individuals have decreased survivorship.  

In which of the following environments would one find the greatest number of endemic species?

Structures such as human arms, bat wings, cat legs, and whale flippers all do different functions, but they contain many of the same bones. These structural similarities are an example of ________.

Everyone cheats in school, and we all know it’s no big deal. 

Within one year of effectively using a specific antibiotic to treat S. aureus infections in a community, all new S.aureus infections could no longer be treated with the antibiotic due to being resistant to the drug. How can this best be explained?

There are a variety of data that act as evidence of evolution. We discussed four key pieces of evidence of evolution in class: direct observations, homology, fossils, and biogeography.List the four pieces of evidence of evolution as discussed in class. For each one, provide either a definition or example. You will also need to discuss how each piece of evidence supports the theory of evolution. Each piece of evidence (name, definition/example, support of the theory) is worth 5 points. The definition/example is worth 2 points, and how each piece of evidence supports the theory of evolution is worth 3 points (20 points total).

A mutation in the hemoglobin protein causes sickle-cell anemia, which can be fatal if both alleles are affected. However, the allele for sickle-cell anemia provides a natural resistance to malaria. Homozygotes either get malaria (if they have two normal alleles) or are resistant to malaria but can die from sickle-cell anemia (if they have two sickle-cell alleles). Heterozygotes only deal with minor effects of sickle-cell and have a high chance of malaria resistance. Which of the following would likely occur in populations where malaria is common?

Using the BNF treatment summaries, what does it state about associated health benefits in relation to the combined hormonal contraceptives?

What is the dose of oral phenoxymethylpenicillin for an acute sore throat in adults?

20.  What interaction occurs and what is the severity if bemiparin is prescribed with aceclofenac or if prescribed with escitalopram?
