Answer:
The correct answer is option A. "Line spectra".
Explanation:
Line spectra is a method that is used to determine the temperature of a star. Line spectra is based on the principle that, depending on the temperature of a star, a line is traced which is compared to the continuum temperature that could either generate a emission (hotter) or absorption (colder) line. A spectrum of lines depending on the temperature have been established under the code OBAFGKM, where O is the hottest an M is coldest.
Answer:
Many plant crops need more phosphorus than is dissolved in the soil to grow optimally. In addition, crops are usually harvested and removed – leaving no decaying vegetation to replace phosphorus. Therefore, farmers replenish the phosphorus ‘pool’ by adding fertilisers or effluent to replace the phosphorus taken up by plants.
Explanation:
Answer;
-Carbohydrates
Explanation;
-Carbohydrates are the first nutrients broken down. It starts in the mouth with saliva and ends in the rectum.The main function of carbohydrates is to provide your body with energy to support muscular work, brain activity, breathing and other important activities. Carbohydrates are made up of sugars known as saccharides.
-Carbohydrate digestion begins in the mouth and is complete when the polysaccharides are broken down into single sugars, or monosaccharides, which can be absorbed by the body.
Although "further disturbances" is pretty vague, both climate change and nonnative species will definitely have a potentially long term impact on an ecosystem
