Hope this helped ya have a good day bro cya)
The efficiency of work is a dimensionless value, and is equivalent to the ratio of the actual work output to the theoretical work requirement. This can be calculated using the equation:
Efficiency = (actual work) / (work requirement) = 123/150 = 0.82
The higher the efficiency, the better performance is given by the system. In reality, efficiency is always lower than 1 which is the ideal value.
According to the Big Bang Theory, the universe began when an explosion had occurred 15 billlion years ago. It consist of an explosion of space within itself. Unlike an explosion of bomb where fragments are thrown upward in the theory it was an exact opposite. Atoms formed when the matter and anti-matter were formed together after it has cooled down.
That would be a covalent bond

Answer:
1.Mitochondria is considered as the power house of the cell as it helps in producing large amount of energy in the form of ATP (adenosine triphosphate) that is used in driving various cellular activities.
2.Through a process called photosynthesis, plants use energy in sunlight to turn a gas called carbon dioxide and water into sugar. Plants then use this sugar to grow. At the same time, plants produce a gas called oxygen as a waste product, which is lucky for us and other animals because we need oxygen to breathe!
3.Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
4.Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2). How does photosynthesis demonstrate the law of conservation? ... The AMOUNT of carbon-dioxide atoms released by respiration are EXACTLY EQUAL to the atoms of these materials contained in the oxygen and carbon converted.The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law because the same carbon atoms are being recycled through the carbon cycle. ... Carbon is used for energy, and some is stored for growth.
