They are markers because their blood level can tell about the human's metabolism, and can predict diseases.
Cholesterol is a natural fat essential to the body. It allows, among other things, the synthesis of vitamin D or bile. It is a constituent of the wall of our cells. Finally, it is part of many hormones, such as sex hormones.Cholesterol has been identified as responsible for certain cardiovascular diseases such as myocardial infarction and stroke.
Insulin is a hormone naturally produced by the pancreas in response to an increase in the level of sugar (glucose) in the blood.Insulin synthesis failure or insulin resistance leads to diabetes, a disease that affects the quality of life of the patient as it will be dependent on daily intake of antidiabetic and insulin, and will be required to adapt a diet. dietetic
Answer:
The key thing to consider here is that water's expansion when freezing is what allows ice to float. The fact that ice remains on top of water is what prevents lakes and rivers from freezing solid. The layer of ice on top serves to insulate the water underneath from the cold air, meaning that life can continue to survive in bodies of water even if they're totally iced over.
If that were not the case, and ice sank, many of the planet's lakes would not be able to support life in the winter. The polar ice caps would also be very different. Whereas the Arctic is a layer of ice floating on top of water, sinking ice would turn it into a giant ice cube extending all the way to the ocean floor. The Antarctic would experience an encrusting of ice all around the continent. Neither of these would be conducive to life.
So, in short, the world would probably support dramatically less life than it does now. Failures of rivers to flow in winter would likely mean that most regions beyond the subtropics would be nearly barren. People would likely have been constrained to the tropics. The oceans would be much lower due to so much ice being tied up in the poles, and there would probably be much less rainfall. This may have made the development of agriculture as we know it impossible.
So, if there were people at all in such as world, they'd probably still be hunter-gatherers, without civilization as we conceive it
Living things has emerged into three domains called Archaea, bacteria, and eukaryotes. Evident that support the idea that multi cellular that is eukaryotic cell evolved from the prokaryotic cell are the descendents of the separate prokaryotic cells that together form a union which are inter dependent.
For example: The mitochondria which is referred to the energy source of the cell is considered as the great-great-great-granddaughter of a bacterium cell which is free living. This free living bacterium bacterial cell was consumed by an other cell and this remained as the stable guest in the cell. This mitochondria provided chemical energy to the cell and also protected the nutrient rich environment. which surrounds it. This process of one organism residing in the other organism completely is called endosymbiosis.
All lipids share Hydrophobic. Hope this help. GOOD LUCK
Fatty acids when need as a source of energy goes through a process called <span>lipolysis and during this process, it is broken down into a useable energy source. </span>
