Individuals of a population can be distributed in one of three basic patterns: they can be more or less equally spaced apart (uniform dispersion), dispersed randomly with no predictable pattern (random dispersion), or clustered in groups (clumped dispersion).
I think its a hypothesis (let me know if i'm wrong)
Answer:
I believe this is an example of Genetic Drift
Explanation:
The Genetics of the given population is stuck in a way that causes the population to drift from one extreme into the other.
Answer:
a) mucosa, submucosa, hyaline cartilage, adventitia
Explanation:
The wall of the trachea can be divided into four layers from the deep region to the superfacial region :
These are; mucosa, submucosa, the musculocartilaginous layer (hyaline cartilage), and the adventitia.
<u>The adventitia</u> is a connective tissue layer that combines with the musculocutaneous layer and with the connective tissue that encircles the trachea. It is composed of loose areolar tissue. This areolar tissue permits a considerable amount of movement of the trachea along its length.
<u>The musculocartilaginous layer</u> consists of the cartilaginous plates, fibroelastic tissue, and the tracheal muscle. The cartilaginous plates number and are composed of hyaline cartilage surrounded by perichondrium.
<u>The submucosa</u> contains many elastic fibers and fat cells and many small seromucous tubular glands, which open into the lumen of the trachea.
<u>The mucosa</u> has numerous low longitudinal folds and is lined with pseudostratified columnar ciliated epithelium, which contains numerous goblet cells and rests on a basement membrane.
I hope that helps!
