does locust have blood?if yes what colour?

Blood is a liguid specially formulated to carry to every living cell of the body all the things essential to life - oxygen and other gases, iron and other minerals etc. It also helps to carry waste and toxins to organs that process them for disposal (lungs, liver, spleen etc). \n\nIn humans and the bigger animals its appearance is pretty obvious (red, gooey stuff), but in many small creatures and insects it is more mixed up with the general chemistry of the creature. They have less developed vascular systems (arteries and veins) and they don't process exactly the same chemicals as us so their 'blood' is a different colour and texture.\n\nFinally, even in humans there is more than one system for transporting stuff around - we also have our lymphatic system which contains a clear fluid called 'lymph'. It is vital in helping us to fight infections and when its working hard in our defence thats when you get swollen glands - these are the lymph nodes - factories for fighting the nasties transported there by the lymph - you have these all over, but especially in your throat, under your arms, in your groin etc. Its what the doctor feels for when you have a temperature.\n\nFascinating stuff!

Its brown colouration comes from a combination of bile and dead red blood cells. In newborn babies, fecal matter is initially yellow/green after the meconium. This colouration comes from the presence of bile alone. In time, as the body starts expelling excess dead red blood cells, it acquires its familiar brown appearance. Throughout the life of an ordinary human, one may experience many types of feces. A "green" and sometimes "clay-like" appearance to the feces is a result in a lack of blood cells expelled. Bile overload is very rare, and not a health threat. Food may sometimes appear in the feces. Common undigested foods found in human feces are seeds, nuts, corn, and beans, mainly for their high fiber content.

(m)\n\nLimulus is a true "blue blood" for, while human blood is red, the blood of this creature is a light blue.  Human blood is red because it has a red pigment called hemoglobin which contains iron.  The Limulus blood contains copper rather than hemoglobin thus giving the blood its blue color.  The animal's blood also contains fantastically sensitive chemicals used by researchers in discovering harmful bacteria called endotoxins, sometimes found in human blood.  In short, the blood of this ancient animal might well save your life some day.

Yes they do. In fact, all insects have hearts but they sure don't look like our big mammalian hearts. A mosquito's heart is a long, skinny, fragile tube that runs along its back, starting near the aNnus', to the chest cavity (the thorax). The tube actually extends to its head but only the abdomen part has muscles to contract and is called the heart.\nA bug's heart contracts (as ours does) to squeeze green (or colorless) blood forward through the heart from chamber to chamber toward the thorax. There the heart simplifies into a plain tube (the aorta) that carries the blood (called hemolymph) to the head. The blood sloshes around in the head, bathing the brain and organs. When each chamber of the heart relaxes, valves open and blood rushes into the heart from the body cavity — but not via blood vessels. \n\nThe blood circulates freely in the body cavity making direct contact with internal tissues and organs. It delivers nutrients, salts, and hormones and whisks away wastes with each heartbeat.\n\nAnuradha

Mosquitos prefer people with a higher iron content in thier blood. \n\npeople with low blood iron are less likly to be bitten. \n\neating bannanas for instance, before you go outside, raises your potassium and iron count, and will make you more attractive to mosquitos.

There is a green respiratory pigments called chlorocruorin, which is green in dilute concentrations, and red in high concentrations. \nHowever, this pigment occurs mostly in annelids (earthworms and their relatives). \nThe greenish fluids in "bugs" (I'm assuming you mean arthropods)could come from defense glands or similar structures, or it could be their gut content in case they were crushed.\nThey have other respiratory pigments, and most are red-violet-bluish in color. Insects don't have pigments.

lice, crabs,  and no...blood stains cannot necessarily give you aids from a  toilet seat.  The blood needs to be fresh and wet...and you have to have a sore or open area for it to infect.  If you indeed worry about it I would consider investing in cavacide.  Kills bacterias etc in 30 seconds air dry time.

If there is any blood present yes.

depends on what you eat. and whats in the food. the amount of iron, if the food has a lot of a certain color. and such. but it can come in all sorts of colors, and in case it is very black, i would see a doc. that means there is bleeding in the body somewhere...

Physiologically speaking, insects have a very efficient respiratory system (at least for aereal respiration and relatively small body size), the trachea. These ducts take oxygen directly to the tissues, thus there is no need for a respiratory pigment. \nEvolutionarily speaking, the lineage of insects is very different from that of vertebrates; their closest relatives have other respiratory pigments. However, as Haysoos has said, some insects do indeed have hemoglobin (convergence).

I have looked and seen.\nThe blood of most animals you are familiar with is red.\n\nYou are most familiar with oxygenated blood which is bright red. When you cut yourself the blood that leaks out is in contact with oxygen in the air and becomes oxygenated.\n\nDeoxygenated blood is a darker red.\nThe deoxygenated blood in veins is NOT visible just by looking at your skin. What you are seeing is the colour of deoxygenated blood viewed through the layers of tissue of the vein walls.\n\n'Blue blood' does not exist except for convenience in diagrams to distinguish it from the oxygenated blood in other parts of the diagram. The other common misconception is the use of 'blue blood' to describe aristocracy - cut of their heads and there is lots of bright red blood!\n\nHOWEVER - there ARE some animals (but none you are likely to have heard of) that do have blue blood - the oxygen is carried on copper rather than on iron.

In humans and other hemoglobin-using creatures, oxygenated blood is bright red. This is due to oxygenated iron in the red blood cells. Deoxygenated blood is a darker shade of red, which can be seen during blood donation and when venous blood samples are taken. However, due to an optical effect caused by the way in which light penetrates through the skin, veins typically appear blue in color. This has led to a common misconception that venous blood is blue before it is exposed to air. Another reason for this misconception is that medical charts always show venous blood as blue in order to distinguish it from arterial blood which is depicted as red on the same chart.

Tell us more. Do you know if you have been bitten by an insect? Is it red also I know it is difficult to see if in back but if you have a mirror maybe you could look. It could be a number of things but we need more information please.

If you spray a plague of locusts, comprising millions of them, with insecticide, most of them will die. Some of them won't - lets say 1%. Of that 1% some didn't die because they may not have had exposure to the insecticide. They will most likely die with the next spraying. Some of that 1%, however, will happen to have an inate resistance to the insecticide, and they will pass it onto some of their offspring. So next year, the farmer will spray, and perhaps 10% of the locusts will survive, so the following year the farmer increases the strength of the insecticide, and only 1% survive, and so on, over many years, gradually the resistance grows, to a level that the insecticide needs to be at a level where it is toxic not only to locusts but to humans, and so has become useless.\n\nAs for bacteria, much antibiotic resistance is plasmid mediated. The plasmid is a small ring of genetic material within many bacteria, it is used to transfer genetic material between bacteria, not just of the same species, but different species of bacteria. The resistance mechanism to antibiotics is similar to the locust example, but it can be transferred to other bacterial species as well, via the plasmid. \nThe good news with antibiotic resistance is that it requires energy to maintain genetic code within the plasmid. If we stop using a particular antibiotic, then having that genetic code within the plasmid will not be an advantage to survival, in fact it may be a hindrance. Eventually it will be lost, and the antibiotic will become potent again. This is of course a simplistic example, but the basics are there.
