The respiratory system is lined with a tissue layer known as the mucous membrane. We discussed how this layer helps to alter the incoming air in three important, beneficial ways. Explain the three ways the mucous membranes alter the incoming air and the benefit of each of these alterations
Answers
Warming, add moisture and trap depris are the three ways the mucous membranes alter the incoming air.
Role of mucous in breathingNasal mucous membranes are lined with small blood vessels that help to warm as well as humidify the air you breathe. They are also lined with cilia which is a tiny hair-like structures that help to trap the debris that you breathe in during inhalation.
So we can conclude that warming, add moisture and trap depris are the three ways the mucous membranes alter the incoming air.

During cell polarization, what are the two resultant edges called?
Answers
Answer:
The leading and trailing edge
Explanation:
Cutting the front edge of each wave's half cycle using leading edge dimming. Trailing edge dimming, on the other hand, eliminates the second half of each wave's half cycle.
~
During cell polarization, the two resultant edges are called the leading edge and the trailing edge.
What do you mean by Cell polarization?Cell polarization may be defined as a phenomenon by which cytoskeletal arrangement, extra- and intracellular signals, and organelle and membrane reorganization occur due to maintaining the cell shape.
Leading-edge works on the front edge and separates the half-wave cycle, while the trailing edge works on the back edge and cuts the second half of the wave.
Therefore, during cell polarization, the two resultant edges are called the leading edge and the trailing edge.

Severe flooding in an area caused a population of minnows to become split into two separate ponds. Prior to the separation, the male minnows all had a moderate number of spots.
Following the separation, the first pond was filled with larger fish that fed on minnows, so male minnows with fewer spots were better able to avoid detection by predators. The minnows in the second pond, however, had very few predators, and female minnows in this pond preferred to mate with males that had the most spots.
After many generations, the two minnow populations evolved into different species and could no longer interbreed.
Fish Species Average # of Spots
Original Species four to six
New Species 1 zero to two
New Species 2 eight to ten
Which of the following best describes why the two minnow populations evolved into separate species?
A.
Natural selection acted upon the traits of the minnows in the first pond only, causing these fish to evolve into a new species with new adaptations.
B.
Natural selection acted upon the traits of the minnows in the second pond only, causing these fish to evolve into a new species with new adaptations.
C.
The same selective pressures were acting upon both populations, leading to a decrease in genetic variation and the formation of two new species.
D.
Different selective pressures were acting upon the two populations, leading to an increase in genetic variation and the formation of two new species.
