The function of the nucleus is to protect the cell’s DNA and control cellular activities. Two of the structures that the nucleus depends on are ribosomes and the nuclear membrane. The ribosomes assist with protein synthesis. Rough ER contains ribosomes on its surface and transports proteins throughout the cell. Smooth ER makes lipids and distributes them within the cell.
Once carbohydrates are eaten, they’re broken down into smaller sugars such as: glucose, fructose, and galactose in order to be used as energy for any immediate tasks.
Lipolysis causes fat cells to separate fatty acids and glycerol to be released into the bloodstream.

Answer:
Explanation:
Forged in the heart of aging stars, carbon is the fourth most abundant element in the Universe. Most of Earth’s carbon—about 65,500 billion metric tons—is stored in rocks. The rest is in the ocean, atmosphere, plants, soil, and fossil fuels. Carbon flows between each reservoir in an exchange called the carbon cycle, which has slow and fast components. Any change in the cycle that shifts carbon out of one reservoir puts more carbon in the other reservoirs. Changes that put carbon gases into the atmosphere result in warmer temperatures on Earth.
