This would be an invasive species which is not native to the environment. It can cause harm either because it over grows (if it's a plant.) Or if it's an animal, it will reproduce and most likely take over the environment. This is because it feels the need to compete for materials, but ends either taking most or all of it. Which then ruins the food chain depending on it's diet. If it's eating a plant, then other animals that eat that plant no longer have any food. And vice versa if it's feeding on animals. Other predators, no longer have their food.
An invasive species! This is because when these are introduced to an ecosystem they can kill or consume native species, leading to native population decline. Sometimes these species are expensive to remove causing economic problems as well.
Shivering occurs when the core temperature of the body begins to decrease which would threaten normal body function. Shivering is a response by the body to bring back temperature back to homeostasis. Trembling is the continual involuntary contraction of muscles. Muscle activity releases heat that warms up the body. This is the reason why we sweat during physical activities as the body sheds excess heat generated by the muscles in order to maintain the homeostatic body temperatures of 37 degrees centigrade.
Cation-exchange chromatography is used when the molecule of interest is positively charged, the stationary phase is negatively charged and positively charged molecules are loaded to be attracted to it. So, the amino acids with negative charge will elute the first. Glutamate, leucin, arginine is the order of elution because of their pI values ~3, ~6 ~10.
Air pressure is caused by the weight of the air molecules above
Explanation:
Air pressure is caused by the weight of the air molecules above. Even tiny air molecules have some weight, and the huge numbers of air molecules that make up the layers of our atmosphere collectively have a great deal of weight, which presses down on whatever is below.
