Answer: They aren't classified as birds because monotremes are mammals, unlike birds. They are referred to as mammals because they have mammary glands responsible for manufacturing and producing milk. Birds cannot do this.
Contemporary landscapes result from many causes, including variability in abiotic conditions, such as climate, topography, and soils; biotic interactions, such as competition, mutualism, herbivory, and predation, that can generate spatial pattern even when environmental conditions are homogenous; natural disturbances. I hope this helps :)
Digestion and Absorption
Mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. In chemical digestion, enzymes break down food into the small molecules the body can use.
The chromosomes are in their condensed, highly coiled form, where they can easily fall without overlapping and staining will show a banding pattern.
