When it comes to the manufacture of antibiotics, what advantages do soil bacteria and fungus have? Antibiotics should only be used when absolutely necessary. Why?
In the early 1800s, potatoes became the main food staple for the people of Ireland. In 1845, a fungus native to South America, Phytophthora infestans, began to infect potato plants, causing potato blight and making the tubers inedible. Over the next several years, most of the potato plants in the country were destroyed by this invasive species.
Which of the following statements correctly explains why the Irish potato famine occurred?
A - The arrival of ships from South America led to human introduction of the disease.
B - A drought across Ireland in 1844 led to more damaged potato plants that were susceptible to infection.
C - An increase in trade with other European countries led to the introduction of plants that were already infected with the fungus.
D - Ireland’s climate became closer to that of South America, which allowed the fungus to infect potato plants and reproduce.
Which statement best describes why antifungal treatments may have side effects to our own cells?
A. Fungal cells and human cells both have cells walls made of cellulose
B. Fungal cells and human cells both reproduce by budding
C. Fungal cells and human cells both have flagella for movement
D. Fungal cells and human cells both have a nucleus, 80s ribosome, and multiple shared organelles

- Why are fungal insecticides an attractive alternative to chemical pesticides for growing food crops? a. Human consumption of fungal insecticides would not make a person sick, but ingestion of chemical pesticides can be harmful to humans. b. A single fungal insecticide would kill a wider variety of insects than a chemical pesticide. c. Fungal insecticides can eliminate both harmful insects and plant pathogens, while chemical pesticides only kill insects. d. Fungal insecticides will decompose dying plants, enhancing the nitrogen content of the soil, while chemical pesticides are not decomposers.arrow_forwardis the potato a living organism? is it alive? how do you know?arrow_forwardWhich of the following is NOT a benefit of normal Flora?
