Question

hii guys ans this please​

Answer 1

1. We should not take antibiotics unncessarilly because they can harm us.
2. After reclassification in 2005, Pluto is no longer classified as a planet because it: Pluto's gravity has not cleared its orbit of other matter and therefore it no longer fits the modern definition of a planet. Earth is round because: its interior rock is warm enough to flow slowly in response to gravity.
3. Very low NOx and PM emissions.
4. Compared to diesel and even to petrol, natural gas creates far less nitrogen oxides (NOx) and particulate matter (PM) when combusted. The combustion process is also quieter. CNG is therefore a better 'urban' fuel than diesel. Lower CO2 emissions, both tailpipe and well-to-wheel.

Hope it helps
