We de-starch leaves so as to remove the starch produced in it during photosynthesis stored as food. Removing the starch would help us to infer our observations clearly as there is no change or substance that would effect the experiment we want to carry out. For example , the indicators we use might give blue-black or green colors just because of the presence or absence of starch.
Answer:
A. It contributes to global warming
Explanation:
- Solar power is the power of the future and is an essential nonrenewable source of energy for man. Solar power is driven by the incoming solar energy in the form of solar rays.
- Solar power is eco-friendly and doe not cause any harm can be sued in the summer season and has ample scope for greenhouse gases.
- As per the statement, the solar power should be used as the main energy source in U.S can be contradicted by saying it contributes to global warming.
That is not true because one you eat your body has to work together to digest the food.
This statement <span>''All systems should aim to achieve 99.999-percent up time''</span> is false.
In reality, all systems should aim to achieve an up time of 99.99%
The different between 0.99 and 0.9999 might not seem a lot but if we actually calculate the percentage points it represents and the amount with which we need to improve efficiently, it almost becomes impossible to reach 99.9999% up time.
