Habitat preservation is when people get together or just one person helps to stop the end of a living space for animals such as the monterey aquarium the help sea life by doing research to see why animals are dying and do what they can to stop it. another one if nation parks or forests you are not allowed to harm them in any way they are protected by laws(the government)
DNA of two species is one of the best evidence to tell us how closely related the two species are.
if we can't see air do fish see water ?
The work function has the formula
E = h v
where
E is the energy
h is the constant
v is the frequency
Since the given is wavelength, we use the relationship between frequency and wavelength
v = c / λ
where
c is the speed of light
<span>λ is the wavelength
</span>
So.
E = h c / <span>λ
h = E</span><span>λ / c = 1.25 eV (475x10-9m) / (3x10^8 m/s)
h = 1.9792 x 10^-15
The work function is:
E = 1.9792 x 10-15 v
</span>
Distance is 15 m + 11 m =26 m
Displacement is North 15 - 11 south= 4 m north.
