1) Density-independent factors may alter birth rates ____.
A but never death rates
B in both small and large populations
C in populations as individuals increase in number
2) Many antibiotics work by inhibiting the synthesis of peptidoglycan, a component of the bacterial cell wall. Which of the following could potentially be a similar target for anti-fungal drugs? (there aren't any real drugs that actually target this fungal feature, but 1 class of anti-fungals does target fungi unique synthesis pathways for different membrane components)
A inhibiting the synthesis of cellulose in fungi
B inhibiting the synthesis of chitin in fungi
C inhibiting the synthesis of peptidoglycan in fungi
D inhibiting the synthesis of lignin in fungi
3) In which lifecycles are spores produced through meiosis? (select ALL correct answers)
A plant-like lifecycle in protists and land plant lifecycle (i.e., the sporic lifecycle, or the alternation of generations)
B the fungal lifecycle (i.e., for most lineages but not the Chytrids and unknown in Microsporidians and Glomeromycetes)
C animal-like lifecycle in protists (i.e., gametic)
D fungi-like lifecycle in protists (i.e., the zygotic lifecycle)
