- A. Most varieties of Sedum are not native plants in Albany or New York City. Why may it be dangerous to introduce a new species to an established ecosystem?B. How does a green roof reduces the amount of carbon dioxide in the atmosphere?C. Why is it important to reduce the amount of carbon dioxide in the atmosphere?D. State one disadvantage of a green roof. E. What are other ways the owners or architects of a building can reduce its carbon footprint?Throughout history, spices have been used as preservatives and to cover up the smell or taste of food that is slightly spoiled. The success of some spices led to a magical, ritualized use, and possession of spices was often limited to priests or other powerful members of the community. a. Choose a spice and trace its use geographically and historically. What is its common use today? b. Spices grow and tend to be used predominantly in warmer climates. ExplainMany cultures and religions have customs which deal with the way they use the land. For example, in Judaism, it is required that a field be left fallow (unplanted) every seventh year. What is one beneficial effect of customs like this? A) They prevent the land from being overused. B) They cause less competition among farmers. C) They make the land more valuable to farmers. D) They force people to farm more recklessly at other times. (Not Graded)
- Doug Schemske is a biologist who studies plants from around the world. Doug and his research team carry out experiments with the plant species Mouse-ear Cress, or Arabidopsis thaliana. They like this species because it is easy to grow in both the lab and field. Arabidopsis is very small and lives for just one year. It grows across most of the globe and in a wide range of latitudes and climates. Arabidopsis is also able to pollinate itself and produce many seeds, making it possible for researchers to grow many individuals to use in their experiments. Doug chose Arabidopsis populations in Scandinavia and the Mediterranean for his research on local adaptation because those two locations have very different climates. The populations may have adapted to have the highest survival and reproduction based on the climate of their home location. To deal with sudden freezes and cold winters in Scandinavia, plants may have evolved freeze tolerance traits, which produces chemicals that act like…In North Carolina and other soybean-producing states, many farmers grow a species of soybean known as Roundup Ready. Roundup is a weed-killing chemical that was produced by Monsanto, (recently purchased by Bayer). The farmer can directly spray Round-up on his fields and it will kill all the weeds, yet leave the soybean plants unharmed. One particular farmer noticed that after a few years of using Roundup weed killer, it became less effective, leaving more andynore weeds alive after spraying. Which of the following explanations, best describes why these weeds remained alive? After years of exposure to Roundup, the soybeans became more resistant to the weed killer. Roundup-resistant weeds were more likely to survive and reproduce than were non-resistant individuals. When Bayer bought out Monsanto, they started selling poor-quality Roundup. Roundup-resistant weeds have less-efficient photosynthetic pathways than the original form.Coffee (Coffea arabica) and Chocolate (Theobroma cacao) are two species of tropical or sub-tropical understory trees that have a rich history in human cultures. Given your knowledge about the plants, and considering the three main pillars of sustainability (environmental quality, economic vitality, and social justice), discuss important considerations for ensuring that coffee and chocolate production can be sustainable for the present and into the future. What are some of the most important considerations? Propose some specific recommendations to increase the sustainability of our relationships with these plant species. Make sure to address all three pillars of sustainability in your answer.
- Prepare a summary of this article without distorting the message it wanted to convey For farmers, pesticides save labor and generally provide a higher yield: they can mean the difference between saving a crop and losing it to disease. Some farmers, especially those who grow produce at a smaller scale, use pesticides sparingly. For example, fruit trees are susceptible to disease in northeastern regions, especially at the blossom stage. An apple or peach grower may spray their fruit trees with a fungicide once in the spring to ensure that the fruit sets, but use no further chemicals for the rest of the season. For many large row crop farmers, on the other hand, regular pesticide use is as much a part of farming as planting seeds. Spraying Roundup on a field of corn genetically engineered to withstand the chemical kills! the weeds without affecting the corn. In comparison to mechanically weeding hundreds or thousands of acres, using pesticides is a game-changer. Some farmers spray their…Certain genetically modified tomatoes were designed to suppress (reduce the effectiveness) the enzyme polygalactonase which delays ripening. How does this genetic modification affect the consumer and the diet of individuals in developing countries? A. Delaying the ripening process means that the tomatoes are more likely to freeze on the vine before becoming ripe. This freezing process locks in the minerals and beneficial nutrients so that the tomato can be transported without losing its nutritional benefit. B. Delaying the ripening process means that the tomatoes are more likely to have a shorter shelf life and have to be eaten quicker. C. Delaying the ripening process means that the tomatoes have a longer shelf life, so they don't rot as quickly. The tomatoes survive delivery to the consumer and provide nutritional value to more people. D. Delaying the ripening process means that the tomatoes can stay on the vine longer to receive nutrients. Once…3. a)The leaves on a plant in your garden begin to turn yellow. From this observation alone, can. you predict which nutrient the plant lacks? Explain. b)How might the fact that plants don’t move influence their ability to adapt to climate change and other environmental changes? c)Would you expect a changing environment to benefit plants that reproduce sexually or asexually? Explain your reasoning.

What are rabi crops? 4. What are kharif crops? 5. Give example for plants belonging to Leguminosae family. 6. Why paddy cannot be grown in the winter season? 7. What is ploughing? 8. How do you separate good, healthy seeds from damaged ones? 10. What is compost? 11. What is Crop Rotation? 13. What is animal husbandry?Danish is preparing a plate of papaya (Carica papaya) for his sleepover friends. As he cuts open the papaya, they discover great 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.
