Overfishing is an example of human impact on biodiversity.
In simple terms, overfishing means that the sea animals hunted for food ( fishes, crustaceans, mollusks etc.) in a year are hunted in numbers greater than the number of newborn individuals of that species in that year. This means that the populations of these animals do not have the time to regrow their numbers.
This results in a dramatic decline of populations of many marine animals.
Answer:
They agree to ethical standards when they are licensed.
Explanation:
1 mole of NH42SO4 contains 42 moles of H. We take the 42 moles of H and multiply that times Avogadro's number (6.02x10^23) and get 2.5284x10^25 atoms of hydrogen
Answer: it is liquid at most temperatures on earth.
Step-by-step explanation:
Answer:
5.9405*10^14 Hz
Explanation:
Remember the equation c=v*λ
v=frequency
λ=wavelength
By manipulating the equation, we can get it in terms of frequency:
c/λ=v
Now convert wavelength to meters (1nm=m*10^-9)
5.05*10^-7m (2 decimal places were shifted to make the number between 1-10, hence the -7 exponent)
Use the manipulated equation:
(3.00*10^8)/(5.05*10^-7), which yields:
5.9405*10^14 Hz (or s^-1)
