Biology
1 answer:
Pie3 years ago
3 0

Answer:

Their diameters  

Explanation:

An equation for the resistance to flow of a fluid through a pipe is

R = \dfrac{8 \eta l }{\pi r^{4}}

where

η = the viscosity of the fluid

l = the length of the pipe  

r = the radius of the pipe

The fourth-power term shows that even small changes in the radius (or diameter) of the passageways will cause large changes in airway resistance.

When the diameter of the airway gets as small as 1 mm, the resistance to air flow is quite large.

ivolga24 [154]

Speciation is the process by which new and distinct species are formed. One of the most important factors necessary for speciation to occur is the genetic isolation of two populations. This genetic isolation can, over long periods of time, cause these two groups to become genetically incompatible. Factors that can lead to this genetic isolation include geographic separation and hostility among population groups.

Why do you get hungry?
suter [353]

Answer:You may feel hungry frequently if your diet lacks protein, fiber, or fat, all of which promote fullness and reduce appetite. Extreme hunger is also a sign of inadequate sleep and chronic stress. Additionally, certain medications and illnesses are known to cause frequent hunger.

Explanation:

"Hunger hormones" (ghrelin) in your blood and an empty stomach signal the brain when you're hungry. Nerves in the stomach send signals to the brain that you're full, but these signals can take up to 20 minutes to communicate -- and by that time, you may have already eaten too much.
