The most important means by which capillary exchange occurs is by diffusion.
<h3>What is Simple diffusion?</h3>
Simple diffusion is a type of passive transport of substances across the cell membrane. It is a process that occurs from the region where the particles are more concentrated to regions where their concentration is lower, until an equilibrium in the concentrations is reached. Thus, diffusion occurs in favor of a concentration gradient. With this, there is no energy expenditure and no need for a carrier for the substances.

C knowing how to dissect a test and the questions
The speed of sound in the atmosphere of arrakis will be 775 m/s when a male ornithoid is flying toward his mate at 25.0 m/s while singing at a frequency of 1200 hz.
Step-by-step solution:
V = Velocity of sound
F' = Observed Frequency = 1240 Hz
f = Actual Frequency = 1200 Hz
= Relative speed of train = 25 m/s
We can derive the relationship from the Doppler effect.
F = f 
V = 
V = 
V = 775 m/s.
What is Doppler effect?
The Doppler effect is a well-known phenomenon in many scientific fields, including planetary science. The Doppler effect, also known as the Doppler shift, describes the changes in frequency produced by a moving source with respect to an observer.
