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. Explain
Miracle RiceRice is staple food in Asia. In the 1950s, Asia faced food shortage and an impending famine. If you have relatives that lived in Asia during the ’50s and ’60s, they may tell you that due to the rice shortage, many starved and those who were lucky had to supplement their diet with other crops, such as barley. In 1962, an organization focused on research and development of rice called International Rice Research Institute (IRRI) developed a high-yielding variety of rice by crossing the two types of rice from Indonesia and China. The result was ground breaking. The new variety called IR8 (India Rice 8) increased its yield as much as 10 times the traditional variety of rice. By the early 1970s, many rice farmers in India, the Philippines, and Vietnam switched to cultivating IR8 rice, making these countries into major rice exporters, preventing a mass famine in Asia, and saving millions of lives. 1) Is the IR8 rice variety considered a genetically modified organism (GMO)? Why or…
The song "Bahay Kubo" is an example of FAITH (food-always-in-the-home) concept. 1)List down all the crops (17-18 crops) you can recall in the song. 2)Choose any of the crops in the song to write in cropping patterns. Use the correct symbols to indicate the cropping pattern involved. A) 2 crops under Intercropping (ex: cassava + corn b) 3 crops in sequential cropping (ex Rice - Corn - Soybean) c) 5 crops in strip cropping

- Certain genetically modified tomatoes were designed to suppress (reduce the effectiveness) the enzyme polygalactias which delays ripening. How does this gene modification affect the consumer and the diet of individuals in developing countries? options: Delaying the ripening process means that the tomatoes have a longer shelf life. The tomatoes survive delivery to the consumer and provide nutritional value to more people. Delaying the ripening process means that the tomatoes can stay on the vine longer to receive nutrients. Once picked, these tomatoes will ripen rapidly to provide a full taste to the consumer. 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. Delaying the ripening process means that the tomatoes are more likely to have a shorter shelf…arrow_forwardMiracle RiceRice is a staple food in Asia.

- Food plants or crops, which have been genetically altered, are known as genetically modified foods. The genetic alteration is meant to make it commercially competitive, yet it is not without environmental and ethical concerns and dilemmas.

Also identify and explain any Four long term negative impact of genetically modified food crop on the environment as well as human health.arrow_forwardCrops gain genetic diversity when large swathes of farmland are planted with the same crop.

- GMOs can be used to create an increased crop rate at a lower price and therefore can be used to solve the problem of world hunger. Introducing GMOs to third world countries can conserve labor, resources, and land. Nutritional value and vaccines added to the crops can improve life in the countries. These proven benefits outweigh the fact that allergies and effects on wild plants are only potential. Explain pleasearrow_forwardAn agriculture lab is trying to improve a type of tomato so that it produces large fruits even under very hot, dry conditions. To do this, they must first identify the genes responsible for the tomato's response to temperature and moisture. Which experimental approach would be most helpful in doing this?arrow_forwardIn 2006, there was a sudden, unexplained die-off of honeybee colonies throughout the United States. The die-off was economically significant because one-third of the human diet comes from insect-pollinated plants, and honeybees are responsible for 80% of the pollination. In October of 2006, the sequence of the honeybee genome was reported. Interestingly, the genome was found to contain far fewer cytochrome P450 genes than do the genomes of other insects. Suggest how the die-off and the paucity of P450 genes may be related.arrow_forward
