The Origin, Distribution and Classification of Cultivated Broccoli Varieties
Of the many different vegetable crops now under cultivation in both the U.S. and abroad, one that has gained increasing importance is that of broccoli. Although it does not constitute a significant portion of most people's diets, it has nevertheless experienced a kind of "revival" in recent years and has become increasingly popular (Schery, 1972; Heywood, 1978). It may even be said that broccoli has emerged from relative obscurity and attained the status of a worthwhile garden vegetable,"(Talbert, 1953).
The botanical family to which broccoli belongs is the Brassicaceae, also known as the Mustard family. The Brassicaceae is a large family comprised of approximately 3,000 described species apportioned among 350-380 genera. The precise number of genera will vary depending on the authority(Heywood, 1978; Keil & Walters, 1988). The classification scheme for broccoli and indeed all of the other brassicas is clear and straightforward until one reaches the species level. At that point the addition of numerous subspecies, varieties, and cultivars results in a rather complex and confusing arrangement of-the taxa in question. For example, the scientific name for broccoli, Brassica oleracea (L.), is also shared by cabbage, Chinese cabbage, cauliflower, collards, brussels sprouts, kale, kohlrabi, and tronchuda kale, to name a few. Despite the fact that all of the aforementioned varieties are similar to one another and to broccoli, and are therefore referred to as B. oleracea, they are nevertheless separate entities. Most authorities today consider there are two major varieties of broccoli, B. oleracea (L.) var. botrytis or cauliflower broccoli and B. oleracea ...

In the first chapter of the book the author discusses a brief world history and evolution of rice crops. It is interesting to see that even though parts of Africa had their own rice crop variety, the globalization of rice crop Oryza Sativa has been slowly replacing the African variety.

Ovarian cancer is the abnormal growth of malignant cells in the ovaries, the egg (ovum) producing part of the female reproductive system. Often, Ovarian cancer goes undetected until it has metastasized (spread) to the pelvis and abdomen. At this late stage, this cancer is difficult to treat. Ovarian Cancer ranks as the 11th most common cancer among women, and it is the 5th leading cause of cancer-related death for women.

When examining the concept of race and ethnicity in Latin America, it can be said that it has quite a different meaning. Latin Americans perceive race as being open ended and explicit, yet racism is quite implicit in their society. They also attempt to adhere to the idea that they are living within a “racial democracy”. Racial democracies are a concept created to convince people that racism does not impact the structure of society and the opportunities that are available to people.
Racial divisions are evident in societies across the globe, and have been for centuries. While there are distinct differences between these relationships of class and race, many similarities are clear. History has shown a long list of tactics to exploit, terrorize, and manipulate racial minorities and lower class citizens. For the indigenous people of Guatemala and the American Indians, the inception of racial and class discrimination occurred during colonialization and continues to show its impact today.
The implications of becoming aware that you have been afflicted with this disease may extend far beyond just a physical condition. Learning that you have cancer can significantly affect a person’s mental, and emotional health. This could cause tension in social relationships, finances, or other lifestyle choices. Becoming more anxious or depressed can considerable hinder a person’s ability to make rational decisions when it concerns their well being. For these reasons, it is crucial for one to seek professional help for all aspects of their lives when they become aware of any serious changes. Although ovarian cancer is an especially detrimental disease, it does not necessarily mean one’s quality of life must be affected; and the stigma of receiving mental/physical help should never inhibit a person’s ability to live a happy and healthy life.
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...
