Answer:
Explanation:Bacteria are all single-celled. The cells are all prokaryotic. This means they do not have a nucleus or any other structures which are surrounded by membranes. Larger bacterial cells may be visible using a light microscope, however an electron microscope would be needed to see the details of the cell organelles.
Answer:
1. TEF
2.RMR
3.TEA
Explanation:
The major components that contribute to the body daily expenditure are as follows
1. TEF(Thermal effect of feeding)
2.RMR( Resting metabolic rate )
3.TEA(Thermal effect of activity)
Generally resting metabolic rate consume 60 to 75% of energy for maintenance thwe body temperature.
When body is doing this some physical work then it is called activity related expenditure.
Answer:
Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.
Bonus: we eat plants
Hope this helps!
So when one scientist turns around and says the mass of an electron is 9.10938291×10^-31 kilograms we know what a kilogram is and so we don't get an answer that it's 32949 microsmiths as he invented his own measurement because he needed one.
