How can insects reduce water loss?
Spiracles form a part of the abdomen region of the grasshopper. They consist of tiny holes that permit air to enter trachea. Spiracles lie along the sides of the abdomen and the thorax. Tubes stem out from the spiracles and carry air to all parts of the body for respiration. The trachea is the respiratory surface of the grasshopper. Since water travels easily along this surface, it is prone to water loss. The respiratory surface is protected thanks to spiracles. Grasshoppers have two thoracic and eight abdominal spiracles. These insects have valves that allow them to close their spiracles, thus reducing water loss. Spiracles are known to possess intricate opening and closing mechanisms that are physiologically helpful to regulate air flow and lessen water loss from the insect
What is the body cavity for stomach ulcer operation?
There is no spinal cavity . . . the spinal cord runs down the back in the spine bones, or vertebrae, and is enclosed on all sides by the vertebrae bones.
Does spider have a heart?
YES!all living creatures have a heart, otherwise they would DIE!
How much empty space is there in the abdomen?
there is no 'empty' space in the abdomen (abdominal cavity) because all the organs fit nice and snug and whatever space is left is filled with fluid.
On which tectonic plate is Nova Scotia located?
Nova Scotia, along with pretty much all of North America and Greenland, is on the North American plate.

How do grasshoppers obtain oxygen?
Grasshoppers and other related arthropods perform their activities with the help of trachea. These are the air filled tubes that are generally open at the surfaces of the thorax along with their abdomen with the help of a pair of spiracles. Spiracles are a kind of valves that allow oxygen to enter and carbon dioxide to escape. They are only used for the purpose of respiration. These tracheoles are found at the end of the tubes i.e. the tracheal tubes. They are insinuated between the cells. They carry the oxygen all through their body. Now, many of the terrestrial arthropods have evolved a sort of close respiratory system that is only composed of the spiracles, tracheae and the tracheoles. These are present for the purpose of transporting the metabolic gases to and from the various tissues.
Do the abdominal segments have spiracles in grasshoppers?
Honey bees have ten spiracles (breathing pores). Three are on the thorax, and seven on the abdomen. The spiracles are the openings to the trachea, which expand and collapse like lungs in response to abdominal wall movement. Two large sacs in the abdomen and smaller ones in the head and thorax lead to very small breathing tubes with blind ends which are filled with liquid which absorbs oxygen and which diffuses into the tissues.
How does a stick insect breath?
Like all insects they have spiracles along the sides of their bodies.
Do stick insects have spiracles?
All insects have spiracles. This is how they breathe because they do not have lungs like vertebrates do!
Do all the abdominal spiracles have segments?
Yes.
Do ants have spiracles?
yes, all insects do

Do crayfish have spiracles?
No. The aquatic kind of spiracle (such as you'd find on rays and skates) could be located only on cartilaginous fish, or the most primitive of the bony fish. The loosest definition of spiracles seems to include a respiratory opening such as the blowhole in whales; lobsters do have ventral openings to the gills but these are anatomically dissimilar to those. (Also since lobsters are aquatic, they do not possess spiracles of the type you'd find on insects.)
What are the openings to the tracheal tubes?
Spiracles are the openings on the sides of all insect's.Air rushes through the spiracles to the tracheal tubes and diffuses into the body tissue and reaches every parts of the body
Why did cities such as Pittsburgh Cincinnati and Louisville grow rapidly in the 1830's?
They all were located along the Ohio River
