There are three different tracheae supplying oxygen diffusing oxygen throughout the species body: The dorsal, ventral, and visceral. The dorsal tracheae supply oxygen to the dorsal musculature and vessels, while the ventral tracheae supply the ventral musculature and nerve cord, and the visceral tracheae supply the guts, fat bodies, and gonads.
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
At the end of each tracheal branch, a special cell provides a thin, moist interface for the exchange of gases between atmospheric air and a living cell. Oxygen in the tracheal tube first dissolves in the liquid of the tracheole and then diffuses across the cell membrane into the cytoplasm of an adjacent cell. At the same time, carbon dioxide ...
Immature cockroaches resemble adults except they are wingless. The cockroach is divided into three sections; the body is flattened and broadly oval, with a shield-like pronotum covering its head. A pronotum is a plate-like structure that covers all or part of the dorsal surface of the thorax of certain insects.
A cockroach's cells divide only once each molting cycle (which is weekly, for the juvenile German cockroach [68]). Since not all cockroaches would be molting at the same time, many would be unaffected by an acute burst of radiation, although lingering and more [ clarification needed ] acute radiation would still be harmful.
The dorsal tergum, ventral sternum, and the lateral pleura form the hardened plates or sclerites of a typical body segment. In either case, in contrast to the carapace of a tortoise or the cranium of a vertebrate, the exoskeleton has little ability to grow or change its form once it has matured.
The smokybrown cockroach is a detritivore and can feed off a wide array of organic (including decaying) matter. [1] Like most cockroaches, it is a scavenger, whereby it feeds on many different types of foods including dry earthworms, pet food, pet waste such as feces and urine, paper, and many types of ripe fruits.
The supraesophageal ganglion lies dorsal to the esophagus and consists of three parts, each a pair of ganglia that may be more or less pronounced, reduced, or fused depending on the genus: Locust brain. The protocerebrum, associated with the eyes (compound eyes and ocelli). [2]
