It is not just the muscle cells that respire. All cells in the body need oxygen for respiration and all cells need to get rid of the carbon dioxide that they produce. In the lungs oxygen is taken from air into the blood and the blood transports the oxygen to the cells in all tissues of the body.As the muscles use the oxygen up,carbon dioxide is produced and absorbed into the blood. And this de-oxygenated blood is pumped back to the heart then on to the lungs. The lungs get rid of this carbon dioxide, and breathe in more oxygen.
Hope this answered your question.
Answer:
A. a cell process that releases energy from food
Explanation:
Answer:
The correct answer is - option III.
Explanation:
An experiment is scientific procedure to test a hypothesis and to demonstrate any scientific procedure to prove something. In high school laboratories there are experiments constitutes scientific methods that helps in demonstrate or prove or existence of something.
Extracting various pigments from the leaves of plants and identifying them by separating from it, is the best example of the high school laboratory experiment among all the options.
Thus, the correct answer is - option III.
The net gain of ATP molecules per molecule of glucose in the reactions of glycolysis is 2.
Glucose is the main source of almost all energy used by cells of similar and different organisms.
In glycolysis process, the production of two pyruvate molecules, a net gain of two ATP molecules, and two NADH molecules takes place.
Use this to help you. So here velocity is not given… so we have to calculate velocity of the car from given data. Car travel 60 km in 35 minutes. Frist of all we have to convert 35 minutes in hours by deviding 35 to 60 hour = 35/60
Next we have to calculate distance in kilometres so distance =velocity ×time.
Velocity =distance / time
Velocity =60/(35/60)
Velocity=3600/35
Distance = velocity ×time
In one hour… it will travel…
Distance =(3600/35) ×1.
By dividing you will get the answer…hope it will
