Answer:
Carbon is the foundation of all life on Earth, required to form complex molecules like proteins and DNA. Carbon helps to regulate the Earth's temperature, makes all life possible, is a key ingredient in the food that sustains us, and provides a major source of the energy to fuel our global economy. The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change. Where the carbon is located in the atmosphere or on Earth is constantly in flux.
On Earth, most carbon is stored in rocks and sediments, while the rest is located in the ocean, atmosphere, and in living organisms. Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms. In the case of the ocean, carbon is continually exchanged between the ocean's surface waters and the atmosphere, or is stored for long periods of time in the ocean depths. Humans play a major role in the carbon cycle through activities such as the burning of fossil fuels or land development. As a result, the amount of carbon dioxide in the atmosphere is rapidly rising; it is already considerably greater than at any time in the last 800,000 years.
Brainlist Pls!
A molecule is a group of atoms bonded together, representing the smallest fundamental unit of chemical compound that can take part in a chemical reaction.
an atom is the basic unit of a chemical element.
chemistry is the branch of science that deals with the identification of the substances of which matter is composed.
(i think this question wasn’t really a question but i answered it anyway lol. i’m sorry that chemistry is hard. good luck!)
Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water
An emerging virus might suddenly appear in a human population if it is airborne, meaning many people will get it at the same time. This causes the virus to spread, initially making a population be affected.
