A patient hyperventilates during a panic attack and begins feeling dizzy and develops muscle spasms. Which change in blood chemistry most likely caused these symptoms?

A dormant viral genome has remained integrated within a bacterial chromosome for many generations without killing the host cell. After exposure to ultraviolet radiation, the virus becomes active and destroys the cell. Which statement best explains this change?

A patient is diagnosed with strep throat and prescribed penicillin. The antibiotic works by interfering with the production of peptidoglycan in bacterial cells. Why would this treatment be effective against bacteria but not human cells?

A patient with severe nasal congestion loses much of the normal function of the nasal mucosa. Which function has been disrupted?

A macrophage engulfs a bacterium and later displays antigen fragments on its surface bound to MHC-II proteins. This process helps activate another type of immune cell. Which immune cell is activated by this antigen presentation?

A premature infant has difficulty breathing due to a lack of surfactant. What is the most likely consequence?

In a monohybrid cross between two heterozygous parents, what proportion of offspring would be expected to show the recessive phenotype? (feel free to use scrap paper to figure this out)
