What is the difference between cellular respiration and the combustion of fossil fuels?
madreJ [45]

Carbon is released into the atmosphere only during the burning of fossil fuels

Explanation:

During the process of fuel burning, carbon is released in the atmosphere. The human invented power plants, factories, cars and other vehicles releases carbon in the form of carbon di-oxide in atmosphere.  

However, the cellular respiration is similar to that of fuel burning as it is too a combustion process. But the carbon produced in this process fuels the inner cellular activities rather than releasing it in the atmosphere.

The food consumed by a male turkey that is 17.5 lbs = 13.6 grams of food per pound * 17.5 pound = 238 grams.

7 gobblers = 7 male turkeys, hence:

The food consumed by 7 gobblers = 238 grams * 7 = 1666 grams

Advocard [28]

Answer:

Epiglottis

Explanation:

The epiglottis is a leaf like structure tat rests above the voice box/larynx and its main function is to seal off the windpipe during eating, so that food is not accidentally inhaled down the wind pipe. When water goes down the wrong pipe, it goes down the windpipe instead of the oesophagus resulting in water going to your lungs which causes the coughing as a protective reflex to clear the windpipe

What role does oxygen and carbon dioxide play in the circulatory system?
Gwar [14]
Oxygen and carbon dioxide is exchanged by the millions of alveoli in the lungs and the capillaries that envelop them. we inhale oxygen (which is then exchanged with carbon dioxide in the lungs) and then we exhale the carbon dioxide. although, the air that we breathe usually consists more nitrogen than oxygen.
