Daucus carota - Origins and New Directions
Daucus carota (carrots) are one of the more commonly used vegetables in the western world. A member of the parsley family (Umbelliferae) which includes caraway, celery, dill, and parsnips, the history of the carrot is somewhat obscure. The potential for enhancing the nutritional value and consumption of carrots, however, may be very promising. Carrots are high in beta-carotene, an anti-oxidant carotenoid that is the carotenoid compound most readily converted to vitamin A when consumed by animals.
Carrots likely originated in the near east and central Asia, from Afghanistan to northwest India, where they were probably cultivated for at least 3,000 years. Carrots may have originally become domesticated through the discarding of the propagating structures after the vegetative structures were consumed. The potential of the remains to continue growth is high. Therefore, it is possible that the disposal of these vegetable tops in garbage heaps may have allowed for colonization of the area and subsequent domestication (Rindos, 1984). Very early evidence of the consumption of carrots also has been found in prehistoric Swiss lake dwellings (Brothwell and Brothwell, 1969).
The original wild-type carrots were thin, wiry, and varied in color from white to purple, but not the common orange that we see today. Wild-type carrots are also known as Queen Anne's Lace. The origin of the name is based upon an English legend. Supposedly, when the future Queen Anne arrived from Denmark to became the queen of King James I of England, wild carrot was still a novelty in the royal gardens. The legend states that Queen Anne challenged the ladies of the court to a contest to see who could produce a pattern of lace as lovely as the flower of the carrot. The ladies knew that no one could rival the queen's handiwork so it became a triumph for Anne (Haughton, 1978). Other common names for wild carrot are bird's-nest and devil's-plague.
Mutations led to changes in the pigmentation. Both the purple and yellow-orange varieties migrated to the Mediterranean where they responded well to cultivation and selection (Brothwell and Brothwell, 1969). Carrots were recognized as one of the plants in the garden of the Egyptian king Merodach-Baladan in the eighth century B.C. The carrot's use was believed to to be limited during this time and throughout the rise of the Greek and Roman civilizations (Brothwell and Brothwell, 1969). Both the Greeks and the Romans were believed to have used carrots for medicinal purposes (Herfruit S.
Whole carrots have a different reaction to the higher concentrations of hydrogen peroxide. There is a dramatic increase in the rate of reaction of catalase enzymes in the whole carrot, meaning that the saturations kinetics can be utilized at much higher rates of concentration.
The first references to the family of plants known as “Beta” can be found in Greek literature around 420BC. They were described as garden plants; dark and light varieties are mentioned. Sugar beet was first grown 2000 years ago originally for its leaves, which were probably the spinach or swiss chard of their day. Beet gradually spread throughout France and Spain, often in monasteries but also by peasant farmers. By the fifteenth century beet was grown all over Europe. The vegetable was probably selected from various Beta species growing around the shores of the Mediterranean. It was widely used for culinary purposes in Europe from the middle Ages onwards.
Humans have long recognized that flowers are an indication of future fruits. Therefore it was vital for nomadic hunters to remember where in the wild they saw flowers. And further yet each type of flower produced a specific fruit. Thus fruits and flowers had something in common; the preference of one fruit meant the preference of a type of flower. Most often, as in modern times, the most healthy looking flower shows signs that it will produce quality fruit. The beauty of a flower told hunters that a nutritious fruits would ripen after the flowers bloomed. This concept explains how we have evolved toward preferring healthy looking flowers. But how does this explain the security of a plants reproduction? It is necessary to mention that plants not only produce fruits to stop herbivores from eating the plant, but in their own diabolic plan, plants found a new way to spread their seeds through fruits. Herbivores would eat the fruits an...
There are many probable methods of introduction of purple loosestrifes. The first probable method is soil that used as ballast in European sailing ship. Since they were discarded in North America, they spread by wind across the Canada. Also, early European settlers were brought plants for their garden. Second probable method is beekeepers’ usage of purple loosestrifes to get more nectar. By beekeepers and early settlers, purple loosestrifes were introduced to Canada.
In the ancient ruins of Peru and Chile, archaeologists have found potato remains that date back to 500 B.C. The Incas grew, ate, and worshipped the potatoes. Also, the Incas would bury the potatoes with their dead. The Incan potatoes had purplish skins and yellow flesh. The Incas called them papas like some people still do today.
Racial discrimination is a concept that is usually identified with the racism and that covers it, although it deals with concepts that do not match exactly. While racism is an ideology based on the superiority of certain races or ethnic groups on other, racial discrimination is an act which, although it is usually based on a racist ideology, not always is. In this regard, it should be borne in mind that the racial discrimination positive (when establishing discrimination in order to ensure the equality of persons affected), constitutes a form of discrimination aimed at combating
ADULT LEARNING THEORY 2 Adult Learning Theory Malcolm Knowles Malcolm Knowles (1913-1997) was a key figure in America’s adult education in the second half of the twentieth century (Smith, 2002). Early Life “Born in 1913 and initially raised in Montana,” Knowles seems to have had “a reasonably happy childhood. His father was a veterinarian and from around the age of four Knowles often accompanied him on his visits to farms and ranches” (Smith, 2002, para. 2). His mother also played a critical role in his character building. During his campaign for the scouting prize, he developed a technique that would help him compete successfully (Smith, 2002), which he always thanked his mother for. In 1930, He entered Harvard University with scholarship, where he spent four dynamic years. Although job opportunities were extremely scarce, he still managed to find a job in Phillips Brooks House at Harvard (National Louis University [NLU], 2005), “a university organization dedicated to social work” (NLU, 2005, para. 7); he also volunteered to participate in many activities with immigrants at Boston's Lincoln House Settlement (NLU, 2005). In addition, he accumulated experiences in communicating with youth groups and counseling for immigrant Italian families. He was even elected President in Harvard's Liberal Club (NLU, 2005). He was soon found to be caught up in the Depression; however, he was not defeated by either the delivery job for the New York Times in the Cambridge area, or the errands he ran as a water boy for the Harvard football team (Smith, 2002). With the desire to work in the field of education, Knowles managed to get a job in new National Youth Administration in Massachusetts, where he was involved in “finding out what skills local em...
Racial Discrimination is a practice where one is treated less favorable due to their race or characteristics associated with he/she race. Within the United States there are many causes of were race matter within society, and unfortunately still does. Although it may not be obvious people still judge others by what they are and what they look like. Racial discrimination is a bias practice that is done everyday. Within this study it was able to point out what exactly leads to those to enable in such thoughts and practices. To be able to do this researchers look upon ones personal life aspects such as point of view, behavior, and environment, which was able to predict how likely one, is to be racial discriminative towards others. Using race a systematic way of life, it is heard for older generation to get out the mentality of looking pass skin color. Although times have change within American society issues such as race will never change.
...her” (Unknown). Smoking is harmful and shouldn’t even have begun with in the first place. To put a single thought about all the bad things that smoking can lead to isn’t hard. Smoking should never even cross the brain. It is crazy how many people just do it so they can “fit in.” That shouldn’t be an excuse to get lung disease, or to ruin cells in the brain. Do not put the harm of others into your hands. Just ask yourself if you can handle the guilt of knowing that someone who doesn’t smoke has “smoker’s lungs” because they have been around someone who smokes. There are so many people today that die, because they have smoked all their life, or even died from secondhand smoke because their parents or spouse have smoked in front of them. So think twice before lighting a cigarette and taking the first puff, think about what all can happen to the body, once addicted.
What is Racial Discrimination? Nowadays people don’t even know because they don’t take the time to learn about one of the biggest threats to our society as a whole. There are 7 most common types of Racial Discrimination. They are Prejudice, Racial Assumptions, Racial Jokes/Slurs, Discrimination, Harassment, Systematic or other times called Institutional Racism and Micro-Inequalities. Let me explain these seven a little more for you.
Before the land of what we no class Turkey, Iraq, Jordan, and other countries in the middle east grains, such as wheat and wild barley, could be seen growing in the wild without human hand to cultivate and nurture it (Authors 2007). Over time, humans began to recognize the benefit of the plants and began the first signs of human agriculture. The skill of farming took time and trial and error, but along the way, humans began to settle down to tend to their crops. Though the first crops were nothing more than seed s thrown about without rhyme or reason to the process we know today such as fields having, rows and sorting out the seeds to create a higher yield each harvest (Authors 2007). Because of the trial and error process, agriculture of plants did not take place of a short period but took many, many years to evolve to what we know today as agriculture; the new fa...
The remains of ancient plants can provide a wealth of archaeological information about a site, with many methods being available to the archaeologist engaged in extracting this data. Perhaps one of the most widely-known of these techniques, possibly because of its attractive nature, is pollen analysis - a technique developed in the early years of the twentieth century by, like so many archaeological techniques, a geologist -- the Norwegian Lennart van Post. To understand the technique and the uses to which it may be put, we must first examine the biological nature of the material itself.
Technology has become a huge part of everyday life, and people seem to have one great debate and are fighting over which is the best phone, iPhone or Android. The Apple iPhone is a cellular smartphone that was created and is maintained by Apple Inc. Android is another type of smartphone that is accessible to consumers, but the operating system is powered by Google and many different companies produce Android devices. The different operating systems and interfaces have created a long and carried out debate to which was superior. iPhone is the better phone and there are many reasons as to why it is superior to its rival, Android. The iPhone’s sleek and beautiful design has users’ hands fondling the device and never putting it down. The operating system is very distinct, but is straightforward with its functionality. People who purchase the iPhone believe that they have received their money’s worth and more when owning and iPhone. The iPhone is better than Android when compared because of the beautiful design and attractive display, the operating system and its functionality, and the device’s personal worth is definitely worth the money spent to own one.
For decades archaeologists believed that plants and animals were first domesticated in the near east (Israel, Lebanon, Syria, south west Turkey, Iraq, western Iran) early in Holocene (8000 to 10000 years ago). It is now possible to mount a challenge to this archaeological dogma about the domestication of plants and animals as evidence of that has been found in Afghanistan and Mehrgarh on the Kachi plains of Pakistan. The roots of sedentism and village farming community have been documented in the 7th millennium BC, at the site of Mehrgarh on the Kachi plains of the central Indus valley. Farming was successful here because it is thought that Pleistocene Indus River flowed in this area...
