1 answer:

7 0

On the islands of the Galapagos lives a group of birds called finches. There are 13 species in this group. These species have diverse ecologies--some eat seeds, some eat insects, some eat fruit, and some even eat cactus. Although the bodies of these species look fairly similar, their beaks are very different. That is because it is their beak that is adapted to these diverse ways of feeding (Figure 8.14).

They separate during meiosis I is true of tetrads.

Explanation:

In Prophase 1, tetrads are formed. Each chromosome has two sister chromatids. When two homologous chromosomes align for crossing over they have four parts and these are termed tetrads.

When homologous chromosome separate tetrads get broken. Tetrads are not present in mitosis because no crossing over takes place in mitosis.

In Anaphase 1 homologous chromosome separate by getting pulled by spindle fibres forming two haploid cells and tetrads get separate.

Place the layers of the trachea in order from deep to superficial.

Assoli18 [71]

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.

The adventitia 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.

The musculocartilaginous layer consists of the cartilaginous plates, fibroelastic tissue, and the tracheal muscle. The cartilaginous plates number and are composed of hyaline cartilage surrounded by perichondrium.

The submucosa contains many elastic fibers and fat cells and many small seromucous tubular glands, which open into the lumen of the trachea.

The mucosa 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!
