The answer is C. distribution.
Rain forests are huge carbon sinks, as plants and trees actively remove carbon dioxide from the atmosphere and store the carbon in biomass. This is a vital ecosystem service for counteracting climate change. Forests regulate the climate, as evapotranspiration from forests influence precipitation patterns and the temperature. Many as yet underdiscovered plants may be of benefit to us as sources of useful products or drugs. Rain forests act as a refuge for vulnerable plant species, thereby protecting them from human over-exploitation and saving biodiversity for future human generations.
Answer:
A compound is a molecule made of atoms from different elements.
Explanation:
All compounds are molecules, but not all molecules are compounds.There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds. They make up compunds because they can join togther .
Food starts to move through your GI tract when you eat. When you swallow, your tongue pushes the food into your throat. A small flap of tissue, called the epiglottis, folds over your windpipe to prevent choking and the food passes into your esophagus.
Esophagus. Once you begin swallowing, the process becomes automatic. Your brain signals the muscles of the esophagus and peristalsis begins.
Lower esophageal sphincter. When food reaches the end of your esophagus, a ringlike muscle—called the lower esophageal sphincter —relaxes and lets food pass into your stomach. This sphincter usually stays closed to keep what’s in your stomach from flowing back into your esophagus.
Stomach. After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chyme, into your small intestine.
Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream. As peristalsis continues, the waste products of the digestive process move into the large intestine.
Large intestine. Waste products from the digestive process include undigested parts of food, fluid, and older cells from the lining of your GI tract. The large intestine absorbs water and changes the waste from liquid into stool. Peristalsis helps move the stool into your rectum.
Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement.
Circulatory system, the digestive system and the excretory system.
These three systems are responsible for controlling, regulating and managing the liquid level of the body. These interdependent systems work together in order for the specie to survive and grow like any other organism.
