Answer:
When the blood and the dialysate are flowing in the same direction, as the the dialysate and the blood move away from the region of higher concentration of the urea, to a region distant from the source, the concentration of urea in the blood stream and in the dialysis reach equilibrium and diffusion across the semipermeable membrane stops within the higher filter regions such as II, III, IV or V
However, for counter current flow, as the concentration of the urea in the blood stream becomes increasingly lesser the, it encounters increasingly unadulterated dialysate coming from the dialysate source, such that diffusion takes place in all regions of the filter

Explanation:
The area between the speed-time graph f a body and time axis measures the distance travelled by the body
But what are the choices??
Answer:
potential energy
Explanation:
this is because potential energy= mgh
so when m= 2m
p.e. = 2 times the previous value
Therefore , When mass is doubled , Potential energy gets doubled. When mass is halved , Potential energy decreases by half.
Answer:
The frequency of a wave is 35 Hz.
Explanation:
Speed of a wave is 140 m/s
Wavelength of a wave is 4 m
It is required to find the frequency. The relation between frequency, speed and the wavelength of a wave is given by :

f is frequency

So, the frequency of a wave is 35 Hz.
