The fungus Botrytis is known to cause rot in fruit and decrease the harvest. In an effort to limit the damage, some agriculturalists spray the soil of orchards with fungicides. The effect of fungicides is not specific for Botrytis and kills most fungi in the soil. In a short answer, predict what would happen to the yield of grapes following fumigation and explain the rationale for your prediction.

Two groups of tomatoes were grown under laboratoryconditions, one with humus added to the soil and one acontrol without humus. The leaves of the plants grownwithout humus were yellowish (less green) compared withthose of the plants grown in humus-enriched soil. The bestexplanation is that(A) the healthy plants used the food in the decomposing leavesof the humus for energy to make chlorophyll.(B) the humus made the soil more loosely packed, so waterpenetrated more easily to the roots.(C) the humus contained minerals such as magnesium andiron needed for the synthesis of chlorophyll.(D) the heat released by the decomposing leaves of the humuscaused more rapid growth and chlorophyll synthesis.
The fungus Botrytis cinerea is a pathogen of plants, and causes high losses of strawberry crops around the world. In Europe, most B. cinerea fungi are killed by fungicides (chemicals sprayed on the crops to kill the fungus). However, some B. cinerea are resistant, and continue to live even when exposed to fungicides. If the currently-used fungicides continue to be sprayed on strawberry crops in Europe, what is expected to happen? (Choose one.) a)The strawberries will eventually become larger and more resistant to fungicides. b)The strawberries will form a beneficial association (mutualism) with the B. cinerea, and both will be resistant to the fungicides. c)Strawberry plants will preferentially be colonized by B. cinerea that are not resistant to fungicides. d) The proportion of B. cinerea that are resistant to fungicides will increase in the population over time, and these fungicides will no longer be effective at killing most of these fungi.
The Irish potato famine was an important historical event that occurred in the 1840’s. The Irish were generally low income, and relied entirely on a particular variety of potato, known as "lumpers”. This strain of potato was susceptible to a rot caused by Phytophthora infestans. This led to wide-spread potato spoilage, which devastated the food supply, and ultimately caused many deaths. What would have been an effective strategy to avoid the Irish potato famine? Plant a more diverse mix of potatoes. Use antibiotics on the potatoes to protect from the rot. Expand cropland to increase the total number of potatoes grown. Use fertilizers, crop rotation, and irrigation to improve potatoes crop yields.
