Discuss the effect of environmental conditions on the Maturation and Ripening Stage of sugar cane
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.

- James is preparing a plate of papaya (Carica papaya) for his sleepover friends. As he cuts open the papaya, they discover numbers of slime-covered seed inside, surrounded by soft flesh and soft skin. Before papaya fruits ripen and the seeds inside them mature, their flesh is bitter or sour. Only later does it become tasty.Discuss how this feature improves the odds for the plant's reproductive success and identify the possible agents to disperse the seeds. Remark: The word count limit is 250 words only, no less than 100 words.arrow_forwardSome 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”?

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?arrow_forwardIn ordinary English, we use the word fruit to mean something sweet and juicy; however, the following things are fruits: peanut shells, pea pods, bell peppers,and chili peppers. What is the characteristic that lets us know these really are fruits even though they are not sweet? In contrast, bananas are fruits that do not have this characteristic (they are sterile and new plants must be grown from buds that sprout near the base of the plant).arrow_forward

Two groups of plants are grown from seed in identical soil types, exposed to identical light conditions, and given the same nutrients. Group A is in a quiet atmosphere. The plants in group B provided with the same atmosphere, except that classical music is played for twelve hours daily in this area. The scientist measures the plants in both groups each day and records the data. In experimental design, Group A is known as.* experimental group control group non-experimental group O quasi-experimental grouparrow_forwardA nine-year research and experimentations have successfully developed rice plants with golden hue kernels instead of the usual white kernels. What is the advantage of this modified rice plant? Select one: To make the plant become resistant to herbivores. To provide sufficient rice produce due to its shorter cycle. To add nutritional value to the rice kernels. To allow easy harvesting and processing.arrow_forward
