Textbook Question
Chapter 30, Problem 4CT
Cattle in industrial dairy farms are typically given rBST, or recombinant bovine somatotropin. This animal hormone increases a cow's milk production, but there is concern that such hormones may have unforeseen effects on milk-drinking humans. There is no similar concern about plant hormones in the plant foods we eat. Why not?

Scientists studied changes in proline, which is an indicator of plant stress and overall protein content in the corn plant when leaves had been consumed by grasshoppers. Corn plants were exposed to varying numbers of grasshoppers and compared to control plants with no grasshopper exposure.
The bar graphs, with error bars, show the mean proline and protein content. The dashed lines show the proline and protein content of healthy plants 10 days prior to treatment.
Which of the following statements would most likely describe the growth of corn plants in this study?
When there is a decrease in the number of grasshoppers (dependent variable) measured against proline and protein content (independent variables), the corn plants would have slower growth and be smaller than the control plants.
When there is an increase in the number of grasshoppers (dependent variable) measured against proline and protein content (independent variables), the growth of the corn plants would be similar…

Imagine a rocky slope in the Santa Ynez Mountains behind Santa Barbara that is covered purple sage (Salvia leucophylla) and white sage (Salvia apiana). Competition among plants is intense, and research has shown that individual plants compete for space via allelopathy.
Imagine that some of the plants (the "mutants") experience a genetic mutation that renders the essential oils in their leaves much less volatile or much less abundant than the essential oils in the plants around them. The most likely outcome for these mutant plants is:

Plants are living organisms that belong to the kingdom Plantae. They are multicellular eukaryotes, meaning they have cells with a nucleus and other membrane-bound organelles. Plants are characterized by their ability to produce their own food through photosynthesis, a process that involves using sunlight, carbon dioxide, and water to produce glucose (sugar) and oxygen. One stressor for a pea plant could be exposure to high salinity in the soil. To simulate this stressor, we can water the plant with a solution containing higher levels of salt than normal. To record the impact of this stressor, we can measure the height and number of leaves of the plant. We can also measure the chlorophyll content in the leaves as an indicator of the plant's ability to carry out photosynthesis. Let's say we have two groups of pea plants, one group is watered with a normal solution and the other group is watered with a high salinity solution. After two weeks, we measure the height and number of leaves of…
