The answer is D. An anion is a negatively charged ion, which means it has accepted an extra electron (s) from a donor ion (cation). To add an electron, energy has to be released so that the electron can be less excited and go back to its orbital level. The released energy is equivalent to the energy required to remove the electron from its orbital level.

Answer:
Matter cycles through an ecosystem through processes called biogeochemical cycles.
Explanation:
Photosynthesis
Plants build carbohydrates by taking in carbon dioxide from the atmosphere.
Carbon moves through the food chain
As organisms eat other organisms, carbon moves up the food chain. Molecules in the food that contain carbon transform into the organic molecules that make up the living body.
Carbon moves back to the environment
Organisms use food molecules, containing carbon, as a form of energy. The process of cellular respiration breaks down food molecules into carbon dioxide.
Contribution of industry
Humans contribute to moving carbon dioxide back into the atmosphere through the combustion of fossil fuels.
Use of fossil fuels
Today's fossil fuels were formed hundreds of millions of years ago by plants deposited in the Earth. The decomposition of the plants slowed down in such a way that their organic molecules are used for natural gas, coal and oil.
Diffusion into the air
From the oceans, carbon dioxide diffuses into the air. This creates a large amount of carbon, which is then taken in by plants to start the cycle over again.
Answer;
-Complex sentence
Explanation;
-Complex sentences are sentences that contain an independent clause and at least one dependent clause.
-An independent clause has the ability to stand alone as a sentence. It always makes a complete thought. A dependent clause cannot stand alone, even though it has a subject and a verb. In this case, the part, " Astronauts can experience bone loss, muscle weakness, and diminished heart function" is the independent clause, while , the part, "when they are exposed to environments with reduced gravity for a prolonged period of time", is the dependent clause.
Answer:
Cattle have never come close to extinction because they are considered to be privately owned, generating profits and social status for producers. On the other hand, buffalo is not of equal value to its human, so Americans became disinterested in breeding buffalo and this led to near extinction in the US.
Explanation:
Buffalo is a herbivorous mammal that belongs to the Bovidae family. It is a large animal that can measure up to 3 m in length and 1.7 m in height. Its weight can reach 900 kg. The African buffalo is wild and native to the savannas of that continent. Although much larger, buffaloes are similar to oxen in appearance. Even similar, buffalo does not have the same economic value as ox, at least in the Americas. This made the breeders disinterested in the buffalo, which led to an almost extinction of the animal on the American continent.
