The nature of light has been the subject of contentious scientific scrutiny for most of recorded scientific history. At the heart of that scrutiny was a debate over the fundamental properties of light: is light a wave or a particle? Ancient scientists like Euclid of Alexandria and Ptolemy of Rome conducted rudimentary experiments exploring the tendency of light to reflect off of smooth surfaces or refract when passing through a medium. These were the first indications of light’s wave properties. Ultimately, this wave theory of light was insufficient in explaining all of light’s phenomena; for example, when light encounters a corner, it will cast a shadow rather than bend around the corner like waves of sound--thus the debate continued. The work of an Italian physicist, Francessco …show more content…
The Gold Beetle has a multi-layered exoskeleton that will allow for interference patterns to create the beetle’s golden appearance. When light strikes the beetle, each layer of its exoskeleton refracts light differently. When the wavelengths of the refracted light are in phase, this additive interference causes the total refracted light to be amplified, allowing the beetle to appear metallic. The beetle also has a secondary mechanism if its highly reflective camouflage fails to protect it. The beetle can pump an orange-pigmented fluid underneath its wing covers which alters the spacing of the layers of the exoskeleton. The change in spacing of the exoskeleton removes the effects of the additive interference, allowing the beetle to mimic another species, the Ladybird Beetle (Hippodamia convergens). While the Gold Beetle is harmless, the Ladybird Beetle is highly toxic and bad-tasting to predators. This example of Batesian mimicry effectively discourages dangerous predators from feeding on the now toxic-appearing Gold
Beetles have various defense strategies, including camouflage, mimicry, and poison. They use camouflage to blend into their surroundings to hide from predators. They mimic the color or shape of other insects to deceive enemies. Many Longhorn Beetles look like wasps, even though they
Every year farmers’ crops are subject to droughts, floods, storms, and so much more. But one of the biggest problems that seem to be plaguing the agricultural industry, specifically the cabbage and lettuce industry, is pests. One pest in particular is the diamondback moth, and it has been wreaking havoc all over New York. However, all is not lost; there still will be cabbage and lettuce in the grocery store. The reason for this? Scientists have come up with an effective new way to manage the diamondback moth, and it isn’t reliant on pesticides. It uses genes. But, best of all, it won’t be one farmer paying for one treatment. It will be a universal movement, and this movement has the possibility to revolutionize the crucifer, or, in more simple terms, the cabbage and lettuce market.
Mountain-pine beetles have drastically changed the environment they are living in; due to this, areas such as industry, recreation, and the ecosystem have been impacted. For the last few decades the mountain- pine beetle has become a huge problem in the Rocky Mountains, stretching all the way from New Mexico all the way to central Canada. More than 60 million acres of forest have been infected, which has resulted in about 60% of the mature pines across North America to be killed (Rosner, 2013). Every day hundreds of trees are felled in an effort to clear out the beetles and to rid the forest of the unsightly dead trees. Entire forests have been reduced into nothing more than standing grave yards that mark a once great ecosystem. Forest Service officials are struggling to come up with a solution to this epidemic but find their options limited due to legal framework, public opinion, and just options in general.
The El Segundo Blue Butterfly is an endangered specie, and it’s been on the endangered specie list since June 1, 1976. They live in the El Segundo Dunes of Los Angeles County in California. They rely on dune buckwheat for their entire life cycle. There are two scientists who have been working on bringing back the butterfly since 2007. The names of the scientists are Travis Longcore and Ann Dalkey there is also a group called “the Xerxes society”. They helped by convincing the “Standard Oil Company” to manage a small portion of the butterflies habitat.
The world is a tough place to survive. If the creatures living on this massive planet cannot adapt in order to survive, extinction will eventually win out. There have been five mass extinctions, and many minor ones, throughout the history of the world. Of course, not all extinctions can be controlled, such as natural disaster and over hunting. However many extinctions, such as no defense against predation, lack of water conservation, no control of osmoregularity, and the inability to adapt to a new environment, can be avoided through natural selection. There is one creature in particular that has mastered the art of surviving against predation:
The Hercules Beetle, which is native to South America, is one of the largest species of beetle in the world. The Hercules Beetle spends most of its life on the ground of the leaf covered rainforests and tropical jungles searching for food. The leafs covering the ground also help hide the beetle from predators. The Hercules Beetle is an omnivore, which means it eats both plants and animals. One of the most distinctive things about the Hercules Beetle are its pincers that look like horns, which are mainly used against other male Hercules Beetles during disputes. The Hercules Beetle has a conservation status of “threatened” and its skin type is shell.
The bombardiers beetle is a small insect that uses a unique form self-defense involving chemical reactions. The beginning of this reaction is in the secretory lobes which produce a highly concentrated mixture of hydrogen peroxide and hydroquinone that is sent to the collecting vesicle. Now, the reaction between hydrogen peroxide and hydroquinone goes like this: the hydrogen peroxide decomposed into water and oxygen; when the oxygen mixes with hydroquinone it produces more water and quinone, a chemical that generates heat up to boiling. Quinone is the goal of the entire chemical reaction, for quinone is the chemical used by the beetle when threatened. However, this possess is not instant and develops over a significant amount of time. This is
In 1993 Volkswagen had record low sales but by the end of 1997 the VW brand had sold 137,885 cars. That was an increase of 178% from it’s 1993 slump. It is safe to say that the the ’94 relaunch of VW on the American Market was a success. The “Drivers Wanted” campaign, developed by Arnold Communications, I believe was successful as a result of excellent market research and positioning.
Of Beetles and Angels by Mawi Asgedom is an autobiography about the journey of Mawi Asgedom. It begins in Asgedom’s hometown of Ethiopia, where he lived during the civil wars that were going on around him and his family. They moved to a Sudanese refugee camp, waiting to be be given a way to come to America. After three years of waiting, immigration offices finally let his family leave Sudan and go to Chicago, Illinois. Though they had just reached a land of opportunity and wealth, Asgedom and his family did not know how to speak English and struggled to make a living in their new home. They lived on welfare and help from programs such as World Relief to help them pay for things
The future is seeming bright for my general population of animals. Sauron ate for me while I was watching for the first time today. He had eaten three whole annulipes- a ravenous appetite for a guy with such a tiny face. I even had the opportunity to hold him a while, while he ate his second pincher bug on my thumb. He handles pretty well for a ground skink. Even the wolf spiders, notorious for having bad temperaments, decided to be on their best behavior for me (Colette especially). Now that I have only one spider- Roman died- it'll be easier to handle her on a daily basis.
Like any other school there were the “cool” kids and the “not-so-cool” kids and like most people I longed for the feeling of fitting in. I tried so hard to buy the right clothes and to talk the right way. I became so caught up in my own life that I did not take a second to stop and think of someone other than myself. Last year, in eight grade, I had the chance to be apart of the “it” group, but during that time I lost myself. Peer pressure had pushed me into a corner where I was unable to think for myself and as a result I lost my ability to establish my character.
Mealworms have a very interesting ecology. They are the 2nd stage in the life cycle of the darkling beetle. Their scientific name is Alphitobius diaperinus. They are also considered pests in the poultry industry. Mealworms have 6 legs and they are located at the front of their body. The mealworms go through their stage of the life cycle in 40-100 days.
God perfectly designed every animal to be fully capable to live their lives just how the need to. Each animal is way too complex to evolved into another form. To proof this, I will show you some amazing animals that God has created. The European Green Woodpecker's tongue comes from the back of the throat, travels from the back of its head, through its nostril, and out of its mouth. Clearly that is way too complex to be evolved, and evolutionist have no idea how because no other animal has that type of tongue. The Bombardier Beetle manufactures chemicals that makes a explosion to protect itself. There's no way that this bug could evolve, it needs all of its parts their all at once or you don't have the animal. God created this bug was created
Where in the World War One animals played a very important role there insects also helped in various ways. The most uncommon insect to take part was glowworm. Its scientific name is Lampyris noctiluca. Glowworms emit light in the dark. About 10 glowworms could provide the same amount of light of a street lamp, They were collected in the jars in huge numbers. Thousands of glowworms collected in different jars were used as lanterns. In the dark trenches soldiers could read letters or study maps and could go through the intelligence reports with help of the light coming from these glowworms.
Light, a concept that has been worked with for many years dating back to 500 B.C. Pythagoras hypothesized that humans perceive light due to the human eyes ability to emit rays upon the environment and the emittance gives a human his or her sight (Sekuler). Afterward, human intellectuals started making it more concise to present day knowledge of light. This development of light came from two intellectuals named Christian Huygens and Isaac Newton. Newton exclaimed during the 1700s that light was a stream of particles carrying energy but Huygens, Newton’s contemporary, thought that light needed this invisible “ether” in order for these streams to make light travel. Then, a couple hundred years later, modern scientists such as Albert Einstein, Thomas Young, and Augustin Fresnel proved Isaac’s and Huygens’ hypotheses of light (Rossing, 23-24). This is how the basis of light was created.
