Answer:
1. In the natural carbon cycle, there are two main processes which occur: photosynthesis and metabolism. During photosynthesis, plants use carbon dioxide and produce oxygen. During metabolism oxygen is used and carbon dioxide is a product.
2. When fossil fuels are burned, they release carbon dioxide and other greenhouse gases, which in turn trap heat in our atmosphere, making them the primary contributors to global warming and climate change.
3. it Disrupts the nitrogen cycle by contaminating the groundwater and making it more difficult for the plants to absorb the nitrogen and causes the phosphorus cycle to accelerate, resulting in an excess of phosphorus in water and soil.
4. The phosphorous cycle is slower than carbon cycle and nitrogen cycle because phosphorous is found mainly in very small dust particles. It moves very slowly from the deposits on land and in sediments and then it is transferred to the organism and from organism it is moved more slowly to the soil.
Answer: The smoke goes to the cells of the mouth or buccal cavity, nasal cavity, trachea, larynx, and then finally distributed into the bronchi (small tubes) in the lungs.
Explanation:
Respiratory system can be defined as the complex system of organs that allow us to obtain oxygen for biochemical oxidation of food and releasing energy in the form of ATP. The breathing is a process in which the air is inhaled inside the respiratory system and oxygen is absorbed by the cells and carbon dioxide is expelled out of the body. The pathway of oxygen is cells of the mouth or buccal cavity, nasal cavity, trachea, larynx, and then finally, distributed into the bronchi (small tubes) in the lungs and it is reverse for carbon dioxide or carbon monoxide gas components present in the smoke. The red blood cells are the cells that are involved in getting rid of smoke out of the body, as they have hemoglobin which has binding efficiency with both oxygen and carbon dioxide. The exchange of deoxygenated blood (carbon dioxide containing blood) takes place in the blood capillaries. From the blood capillaries the carbon dioxide is expelled out from the bronchi following the entire route of expiration.
Well usually it takes a couple of weeks and u have to take a test to find out if ur pregnant
