Answer:

7

Explanation:

Let the middle number be x.

Since  the middle number is 1/3 the last number, then the last number has to be three times the middle number,

Therefore the last number is 3x

The first is 3 times the last number, meaning the first number has to be 3*3x=9x

All the three number add up to 91,

thus 9x+x+3x=91

13x=91

x=91/13=7

What is the most important means by which capillary exchange occurs
Vesnalui [34]

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.
