Alternative source of energy such as Solar power, nuclear power , hydroelectric power , bio fuels , geothermal power, wind energy etc have potential to provide energy with much lesser pollutant emission , hence improving air quality and reducing greenhouse gas production
<u>Explanation:</u>
- One of major environmental issue –Air quality having large dependence on atmospheric emission, especially from burning fossil fuel
- Fossil fuel combustion results numbers of air pollutants, which are harmful to health as well environment. It is one of major reason of global warming.
- SO₂(Sulphur oxide) and NOx (nitrogen oxides) which are byproducts of fossil fuel combustion when emitted into atmosphere causes smog and acid rain
- Alternative source of energy produces less pollutant which help in protecting air quality and water quality. It also causes much less damage to public health, global warming , wildlife loss etc comparative to burning fossil fuels
The nucleic acid is DNA best conclusion the scientist can make based on the observation
Answer:
Facilitated diffusion involves transport protein
Explanation:
The spear is 4620 years old.
N=N0e^-kt
N0 = initial amount of C-14 (at time t = 0)
N = amount of C-14 at time t
t = time, in years
k = 0.0001
N/N0 = e^-kt
we know N/N0 is 0.63
so we have:
0.63 = e^-kt
we can take the ln of both sides, leaving us with:
ln0.63 = -kt
t = ln0.63 / -(0.0001)
t = 4620 years
hope this helps with your thing!
