The normal core body temperature of a healthy, resting adult human being is stated to be at 98.6 degrees fahrenheit or 37.0 degrees celsius. Though the body temperature measured on an individual can vary, a healthy human body can maintain a fairly consistent body temperature that is around the mark of 37.0 degrees celsius. The normal range of human body temperature varies due to an individual’s metabolism rate, the higher (faster) it is the higher the normal body temperature or the slower the metabolic rate the lower the normal body temperature. Other factors that might affect the body temperature of an individual may be the time of day or the part of the body in which the temperature is measured at.

Edible plant stems are one part of plants that are eaten by humans. Most plants are made up of roots, stems, leaves, flowers, buds and produce fruits containing seeds. The edible portion in an onion is swollen leaves with a bit of stem. They are bulbs which, like garlic and leeks, are modified stems in which the primary storage tissue is expanded leaf bases. They come in white, yellow, and red varieties.

The green color in leaves is caused by the presence of a compound called “chlorophyll,” which the plant produces to do photosynthesis, which is how plants get energy from sunlight. The purpose of chlorophyll is to assist the plant in making food for itself by utilizing energy from sunlight and nutrients from the soil. The chlorophyll is green because it absorbs red and blue wavelengths of light — and so green is not absorbed and is reflected, making the plant look green to our eyes.

The Indian government has established 18 Biosphere Reserves of India, (categories roughly corresponding to IUCN Category V Protected areas), which protect larger areas of natural habitat (than a National Park or Animal Sanctuary), and often include one or more National Parks and/or preserves, along buffer zones that are open to some economic uses. Protection is granted not only to the flora and fauna of the protected region, but also to the human communities who inhabit these regions, and their ways of life. Eight of the Eighteen biosphere reserves are a part of the World Network of Biosphere Reserves, based on the UNESCO Man and the Biosphere (MAB) Programme list. In 2009, India designated Cold Desert of Himachal Pradesh as a Biosphere Reserve. And, on September 20, 2010, Ministry of Environment and Forests designated Seshachalam Hills as another Biosphere Reserve taking the count to number of such designated areas to 17. And, on August 25, 2011 Panna (Madhya Pradesh) became India’s 18th Biosphere Reserve.
