Answer:
Cell membranes in cold tolerant winter wheat plants have a higher ratio of unsaturated fatty acids to saturated fatty acids than do cold intolerant wheat varieties.
Yeast cells that produce more unsaturated fatty acids than saturated fatty acids in response to cold have greater cold tolerance.
Explanation:
The organisms which live in cold environment must have more amount of unsaturated fatty acids as compared to saturated fatty acids because <u>unsaturated fatty acids tend to freeze at comparatively lower temperature which provides the organisms an advantage and better adaptability to live in such environments. </u>The unsaturated fatty acids will not freeze easily even in cold environment and their body/cell will keep working perfectly even in cold weather. In contrast to this, the saturated fatty acids will freeze easily and the whole system of that organism will collapse during winter season.
Same goes with yeast. more unsaturated fatty acids in the body as compared to saturated fatty acids will help the yeast to live in cold environment. The reason for better adaptability is same as above.
For years, cholesterol has been a major concern for millions of people around the world. The fear of cholesterol has led to many people going to specialists like physicians and nutritionists. The people have heard stories from family and friends who have had high cholesterol and they fear heart disease and other crippling diseases like Atherosclerosis and Heart Disease the risk of these diseases increases as the blood Cholesterol rises. Most people don't know what this molecule is; it is help full if there are not to many of them. The majority of the population is conscious of the harm that cholesterol can cause, but they are not aware that it has useful values to our body. Over 25% of the population of the United jStates has elevated cholesterol. There are two major forms that cholesterol comes in: 1) Low Density Lipoprotein, which is generally considered "bad" cholesterol or (LDL's) and 2) High Density Lipoprotein, which is known as "good" cholesterol or (HDL's). Although given these names, there is nothing inherently good or bad about them. The facts coming up will clarify a lot of the misconceptions that are associated with cholesterol and the overall effect that cholesterol has on the human body. .
Cholesterol is a soft, fat like substance made up of carbon, hydrogen, and oxygen, that is found in all the body's cells and is used to form cell membranes, assemble hormones and other necessary substances. It is an organic compound belonging to the Cholesterol family that also encompass steroids. Cholesterol is produced two ways. The first is by the liver. The liver produces about 50,000,000,000,000,000 cholesterol molecules a second, or about 1,000 mg of cholesterol a day. But the liver also removes some Cholesterol from the blood. The second is by the intake of the foods eaten like animal fats (saturated and polysaturated fats) such as cheese, lard, egg yolks, red or marbled meat, pork, processed meat, gravies, palm or coconut oil, deep fried foods, whole milk, butter.
