... derivatives of are important. Ascorbic acid (vitamin C) is derived from glucose. Important sugar alcohols (alditols), formed by the reduction of (i.e., addition of hydrogen to) a monosaccharide, include sorbitol (glucitol) from glucose and mannitol from mannose; both are used as sweetening agents. Glycosides derived from are widespread in nature, especially in plants. Amino sugars (i.e., sugars in which one or two hydroxyl groups are replaced with an amino group, -NH2) occur as components of glycolipids and in the chitin of arthropods. carbohydrateClasses of carbohydrates Sources The most common naturally occurring are D-glucose, D-mannose, D ...

Crohn's disease can also affect the also affect the colon, the regional lymph nodes, and the mesentery (outside covering of the intestines). The disease can be aggravated by a bacterial infection. It begins with the development of patches of inflammation on the intestinal wall, which can spread from one part of the digestive tract to another. It sometimes only develops in one place and does not spread any further. The inflammation causes the thickening of the intestinal wall, which sometimes causes an obstruction in these areas, or scar tissue, wh ...

... stroma and like the chloroplast, the mitochondrion is a semi-autonomous organelles containing the machinery for the production of some of its own proteins. The main function of the mitochondrion is the oxidation of the pyruvate derived from glycolysis and related processes to produce the ATP required to perform cellular work.(Campbell 182-9) Pyruvate, or fatty acids from the breakdown of triglycerides or phospholipids, pass easily through pores in the outer mitochondrial membrane made up of a channel protein called porin. The inner membrane is a more significant barrier and specific transport proteins exist to carry pyruvate and fatty acids into the matrix. ...

The new adult mosquito escapes from the pupae skin be splitting the skin open and resting at the water surface to allow its' body parts to harden. can complete the entire egg to adult cycle in 10 to 14 days, depending on the temperature, with shorter times during warmer periods. Some species can even reach the adult stage in as little as two to three days. Why Do We Need ? Mosquitoes are very abundant. Many of the eggs that mosquitoes lay in the water, and never become adults. They are eaten by fish, insects, frogs, toads and other amphibians. They are a major food source ...

... second highest cause of water pollution is ship waste. Ships used to take much garbage with them on their ships and dump them. This was very common until the government took action. They were giving sailors up to one million dollars fines for disposing waste. Because of that, ships now carry less garbage with them. Animals are not the only thing being harmed by water wastes. Fishing lines, rope, and plastic nets are being caught in the rutter and the engine, but the ships are not exactly perfect. The other main cause of water pollution is industrial waste. Industries do not be harmed by water pollution but the cause much it. Many companies pour chemicals i ...

... to Lord Shelburne at the time of his most significant experimental work, and Carl Wilhelm SCHEELE (1742-86), a Swedish pharmacist and chemist. It is generally believed that Scheele was the first to isolate oxygen, but that Priestley, who independently achieved the isolation of oxygen somewhat later, was the first to publicly announce his findings. The interpretation of the findings of Priestley and the resultant clarification of the nature of oxygen as an element was accomplished by the French scientist Antoine-Laurent LAVOISIER (1743-94). Lavoisier's experimental work, which extended and improved upon Priestley's experiments, was principally responsible for the u ...

... sexes, are generally similar in coloration (Womack 1993). The female adult is noticed by it’s small dark figure that is colored by white markings and banded legs. Its proboscis or snout is mostly black with regard to the white palp tips (Russel 1996). The dorsal pattern of white scales on the scutum is in the shape of a ‘lyre’ with two central based stripes that contrast with the dark scales present on the insect (Womack 1993, Russel 1996). Its wings are dark scaled and femur and hind legs are pale scaled for about three-quarters, and dark scaled for about two-thirds (Russel 1996). The first through the fourth segments of the hind tarsi are charact ...

... (by meters) that is traveled from the crest of one wave to the crest of the next. Radio frequencies are measured in units called kilohertz, megahertz, and gigahertz. (1 kilohertz = 1000 hertz : 1 megahertz = 106 hertz, 1 gigahertz = 109 hertz). All radio waves fall within a frequency range of 3 kilohertz, or 3000 cycles per second to 30 gigahertz. Within the range of frequencies, radio waves are further divided into two groups or bands such as very low frequency ( VLF 10-30 kHz ), low frequency (LF 30-300 KHz), medium frequency ( MF 300-3000 KHz), high frequency ( HF 3-30 MHZ) and very high frequency ( VHF 30-300MHZ). Amplitude modulation is the oldest ...

... per year per cow. It is necessary ;however, that the producer be well educated on how to handle twinning, in order for it to be successful for them. Many agencies see twinning as an economic move upward. The American Breeder Service has made efforts to produce semen as well as embryos with high predicted breeding values available to producers. They have been recorded based on twinning probabilities and ovulation rates. A large amount of work on twinning has also been done by the Meat and Animal Research Center. Since the early eighties, they have located cattle with a high frequency of twinning and been forming a breeding foundation based on this charact ...
