- The data that is attached below was collected during a lettuce seed ecotoxicity assay. Lettuce seed assays are used to compare the ecotoxicity of methanol, ethanol, and isopropanol by these alcohols' effects on germination rate and root elongination. Using the attached data, help answer which alcohol seems to be the most toxic to lettuce seeds. Why or why not would your results be expected? What does this information tell you about using ecotoxicity data to estimate human toxicity?Figure 4 shows an open stoma during a gaseous exchange process in a plant. H2O H2O. H2O y. H2O. H2O Rajah / Figure 4 Huraikan proses pertukaran gas dalam tumbuhan dengan mengambil pengaruh Y kepada kesegahan sel pengawal. Elaborate the gaseous exchange process in plants with considering the influence of Y to the turgidity of guard cells.Which of the following explains why pea plants in high soil nitrogen conditions have so few rhizobial nodules on their roots? When there is already high soil nitrogen there is a very large cost to having rhizobial nodules. The rhizobia bacteria in the nodules fix nitrogen when there isn't enough in the soil, so when there is already high soil nitrogen there is no advantage for the pea plant to expend the extra energy housing the rhizobia. The rhizobia bacteria in the nodules use nitrogen when there isn't enough in the soil, so in conditions of high soil nitrogen the plant tries to exclude the rhizobia to keep the nitrogen for itself. When there is already high soil nitrogen there is no benefit to the plant to having rhizobial nodules, which can rob the plant of the high nitrogen supplies so that the rhizobia bacteria do not have to fix the nitrogen themselves.
- Some genetically modified plant varieties incorporate a “self-destruct gene”, which causes anyseed produced by the plants to be unable to germinate.a) What are some ecological advantages to these “self-destruct genes”? Explain youranswer.b) Identify another reason why the enterprises that developed these varieties might haveincorporated such genesB) Describe the mechanisms employed by two types of plants to minimize photorespiration and ensure that the CC is carried out even when environmental conditions are not in their favor. Be sure to identify 1) the type of plant, 2) its natural environment and how it affects the plant's ability to perform the CC, and 3) how it has adapted itself to minimize photorespiration. 4what type of stem modification does: -Gloriosa superba-Ficus benghalensis have?

- You have been chosen as the lead student gardener for the CSUMB Future Farmers of America Club (FFAC). Your club is looking to you and your Bio211 plant experience to guide them. You arrive at the new FFAC garden plots where your club mates show you their cherry tree that they've been having trouble with.
