When food is digested, the food is broken down into Glucose, which can get into the bloodstream through the small intestines. It travels around the body in the bloods plasma and is then diffused into the body's cells through the capillaries. Once the Glucose is in the body cells, it can be used for respiration.
The breathing system is used in respiration because we need it to respire aerobically, so that our body gets all the vital oxygen it needs. When we breathe, oxygen is stored in the alveoli in the lungs. From there, it can be diffused into the bloodstream, to be used for respiration.
The products of aerobic respiration is Carbon Dioxide and Water. The Water leaves the body as sweat or waste such as urine. The Carbon Dioxide is carried through the blood to our lungs where we can breathe it out. Where as in anaerobic respiration, the product is Lactic Acid. This ends up being broken by oxygen after exercise (oxygen debt) and is also turned into Carbon Dioxide and Water.
Appositional growth is the term for the rise in diameter. The periosteum's osteoblasts build compact bone around the exterior bone surface.
The answer is D, 15,000 x 0.2= 3000 add that together =18,000
Glucose, water etc.... doesn't require ATP !
these molecule does not require energy to pass from the cell. it happens according to concentration gradient or by passive transport !!!
The<u> troposphere</u> is the lowest layer of our atmosphere.
The next layer up is called the <u>stratosphere. </u>
Above the stratosphere is the <u>mesosphere</u>.
The layer of very rare air above the mesosphere is called the <u>thermosphere.</u>
Although some experts consider the thermosphere to be the uppermost layer of our atmosphere, others consider the <u>exosphere </u>to be the actual "final frontier" of Earth's gaseous envelope.
The <u>ionosphere</u> is not a distinct layer like the others mentioned above.
