Cockroach blood is not red because they do not use hemoglobin to carry oxygen. In fact their bloodstream is not used to carry oxygen either. They use a system of pipes called tracheae to bring the oxygen and remove carbon dioxide from their tissues. a result other factors determine the blood color. Male cockroaches have relatively colorless blood. Larval females have colorless blood.

Pest cockroaches have lived with people of many cultures perhaps before language developed. Here is a link to the common names given to cockroaches in different cultures: Some common names have some suggestive associations. (1) Water Bug. (2) The German cockroach, Polish cockroach, Russian cockroach, Crotton bug all refer to the same species Blattella germanica because one community wanted to name it after something they despised.

Insects as a group are said to think in their periphery. This is because many of their innate behaviors are hardwired in peripheral ganglions more so than vertebrates. For instance flying behavior is controlled in the thoracic ganglia and some reproductive behavior such as copulation is controlled in the last abdominal ganglion. Whenever sexual behavior or flying behavior has to be coordinated with the visual system the behavior includes what you might call the brain (head ganglion). See similar questions...

Thigmotropic. [Greek thigma, touch; as in thigmotaxis + -tropism.] This is a word used often in the plant world where a plant entwines itself about another object such as a vine climbing another vine or a tree or a string. Cockroaches are thigmotropic in the sense that they like to conform to a hiding place during the day, conforming to a curve or having something touching them on top and bottom such as in a crevice. Cockroaches and many other animals can lay eggs (infertile) without mating. See similar questions...

Emotion is not usually associated with insect or cockroach behavior. The cold and unmoving surfaces of the insect exoskeleton do not allow for movement of surface muscles and skin that one can interpret as a smile or other facial emotion. Insects react to environmental cues with reflexes that we usually do not interpret as emotion. Is a bee worker angry when it stings an intruder to the hive? We subjectively use the terminology "angry worker bee". See similar questions...

A group of tests that are important for diagnosing lupus will be performed. The results of these tests (serology) will be sent to you if you choose to receive them. The DNA in your blood will be analyzed to determine which genes may be involved in lupus and to address other scientific questions about lupus as they arise. A permanent cell line will be established and this cell line may be used for other approved lupus research at a later time. See similar questions...

You can give blood every 56 days (8 weeks). Every time you donate, you will have to meet the same criteria as you did before, and pass the medical examination. See similar questions...

This is clearly an assignment from someone who knows the type of answer they want. I am not sure what the questioner wants. I imagine that the majority of the approximate 3000 cockroach species are largely on their own in the environment. Their support is based on their membership and place in the food web. They are omnivores and thus eat almost any organic matter that does not fight back. They are eaten by many small lizards, amphibians, mammals, and birds. See similar questions...

Color is the perception of the power spectrum that is striking our retinas. Cells called cones are responsible for our perception of color. There are three distinct types of cones and each type covers a different region of the spectrum. The cones are typically labeled as red, green, and blue, which gives the incorrect impression that each responds to a distinct frequency. In fact, there is significant overlap between them, especially in the case of red and green. See similar questions...

Cockroach management and control is best accomplished by removing sources of food and household food wastes. Foods should be stored in sealed containers. Every attempt to reduce access to water should be made such as fixing leaking faucets or preventing condensation on pipes. Improving ventilation to eliminate damp areas is helpful. Caulking or sealing cockroach access and entry points is also helpful. See similar questions...

The reproductive cycle like the life cycle depends on the temperature. It is maximum for most pest species at 30?C which is about 86?F. At that temperature an egg case is produced by _Blattella germanica_ adults in about 6 days but it is held by the female for 18 days before they hatch. The other common pest species, _Periplaneta americana_, deposits an egg case every 3 days at 30?C and each egg case will hatch in about 30 days. See similar questions...

Each of us has a complete set of our genetic information in almost every cell of our body. Genetic information consists of our genes, which we inherit from our parents. Genes are made up of DNA. A simple, reliable way for us to get a copy of your DNA is through a blood sample. We then use that DNA to try to determine the location of risk genes. See similar questions...

It is the blood obtained from the umbilical cord at birth. The cord blood contains stem cells. Stem cells are the cells that make all of the other cells in your body, i.e., heart cells, neural cells, etc. These stem cells continue to reproduce throughout life unless they are destroyed by cancer or blood disease. If your stem cells are destroyed, you will die unless they are replaced by transplant. See similar questions...

You must be at least 17 years old, weigh at least 110 pounds and be in good health. There is no maximum age limitation as long as you are in good health. Blood pressure medication - most are allowed, blood pressure must be acceptable on the day of donation. Check with CBB nurse. Malaria exposure - if you travel to a malaria endemic area with or without medication, wait one year. See similar questions...

Blood Pressure is the pressure of circulating blood against the walls of the arteries. Your heart is like a pump. When it contracts, or beats, it sends a surge of blood through the blood vessels and pressure increases. This is called your systolic pressure. When your heart relaxes between beats, your blood pressure decreases. This is called your diastolic pressure. These two numbers provide important information about your health.

Most patients do not require blood transfusions. Your doctor will have discussed or will discuss this with you. See similar questions...
