Dogs have strong muscles‚ and their legs are long and almost slender. Like dogs‚ and most other animals‚ dogs run on

effects of the natural insect repellent on the different species of insects to be used in this study? II. Background of the Study : An insect repellent is a substance applied to skin‚ clothing‚ or other surfaces which discourages insects and arthropods in general from landing or climbing on that surface. Most pesticides and insecticides are used in homes‚ gardens and farms to kill or deter pests and insects. Insects and pests need to be kept away because they cause diseases and cause damage to

Arthropod Genetics Passing of Traits One bright and sunny Australian afternoon‚ Joy the Christmas Island Crab met her dream crab‚ a ten-legged green caped crab. They fell in love and had a beautiful crab wedding. The Generation one crustacean body’s phenotype was a plastic cup while the genotype was BB. The legs’ phenotypes were pearly white pipe cleaners and the genotype was ff. The crustacean had deep blue pom poms for eyes and the genotype was Ii. For antennae‚ the crustacean had soft qtips

Entomophagy People eat parts of insects in everyday life by taking the nutritional value without observing that. Many food products use insects to develop and reach perfect results with lower costs. Food laws in many countries do not prevent using insect parts in food‚ but they determine the quantity. For instance‚ the average of the insect fragment in wheat flour is about 150 or more per 100 germs. Researchers recently found that thousands of years ago people ate the insects as the main

up between six million and ten million different species. That’s an insane amount of variety! The Insect Fair puts this variety into perspective. I spoke with the manager of the Farm Store Dawn Taccone about the fair. He noted how diverse all the arthropods are from each other‚ saying‚ “[they] have 500‚000 insects split between several thousand different species.” My first stop was to one of my all-time favorites‚ the caterpillars. Unfortunately you can not touch most of them since they can be poisonous

Termite Handedness Summary: Animal behavior is the underlying concept of how living organisms act when presented a certain situation or environment. Understanding animal behavior in simple organisms such as termites can give us basic insight into how animal behavior works. In our experiment we tested termite “handedness” – if termites prefer to turn left or right. We did this by placing a termite in an ink path with a fork in it which would cause the termite to choose between going left or right
