The answer is variant C because every living organism needs water to survive. A human can live without water only 6 days, after that period the most important organs start to shut down because of the lack of water.
Answer:
Wavelength=75 cm.
The wavelength well remain unchanged which is 75 cm.
Explanation:
The formula which will help us to answer the question is:
V=f*λ
Where:
V is the velocity
f is the frequency of wave
λ is the wave length
Now:
λ=V/f Eq (1)
The equation show's that wavelength is independent of the amplitude but it depends on the frequency and the velocity with which wave is moving.
The wavelength well remain unchanged which is 75 cm.
Use the equation
The final velocity 
is 68 m/s, the acceleration 
is 8 m/s^2, and the net displacement 
is 33 m, so you can solve for the initial velocity

Phytoplankton are plant organisms that live in the upper, sun filled layers of the ocean. T<span>he function of the phytoplankton in ocean ecosystems is <em><u>A. Producer</u></em></span>
we know that
Power efficiency is defined as the ratio of the output power divided by the input power:
so
in this problem
%
Substitute in the formula above
therefore
the answer is
