Chameleons Organism Physiology Essay Example for Free

Chameleons Organism Physiology Essay We know that an organism is anything that is living and can function by itself. This paper will help understand chameleons and how they have evolved to adapt to their surroundings. It will also discuss their physical features inside and out. Myths and facts will be revealed, as well as a few comparisons between sexes. Though there are many species of chameleons, everything discussed will be in reference to them as a whole. Chameleons are part of the reptile family. Half of their population lives and originated from Madagascar. Others can be found in the Middle East, Europe, and India. Fossils show that chameleons have been around for more than 26 million years (Klappenbach, 2014). The two scientific names given to them are Brookesiini and Chamaeleonini. Their known life span is to be around five to nine years (Switch Zoo , 2013). They are omnivores and carnivores, so their diet consists of insects, fruit, animals and flowers. There are also more than 135 different species of chameleons and six different subfamilies, which are Bradypodian, Brookesia, Calumma, Rhampolean, Chamaeleo, and Furcifer (Chameleons Online, 2002). The bulge underneath their tails can determine the sex of a chameleon visibly. This specie is commonly found in three types of habitats. The main one is the forest, where there are many trees and bushes for them to travel and hide. This is the same for scrublands, which is the second habitat. It is common for chameleons to want to stay off the ground and higher up, but few do like to make home in fallen leaves and sticks in large open areas. The third habitat is the desert, and even though it is hot and dry, few chameleons can still survive. Chameleons possess many features that are critical to their  survival, i (Komeleons). The first and well-known feature is their skin color. Their skin helps them to blend into their environment, but also stand out. They are able to regulate their body temperature and communicate based on the color of their skin. The important thing to know is that a chameleon’s skin color is a reflection of their feelings. When they feel threatened and s cared they will turn a dull color like a grey or a brown. When they feel dominant and want to defend themselves or their territory they will turn bright colors to seem more intimidating. There is evidence that suggests that chameleons evolved to stand out not to blend in. The reason their skin is able to change so many colors is because there is a layer of different pigments underneath known as chromatophore cells. There are four layers of skin cells that go in the order of yellow, red, blue, and brown in color. The color changing is from their hormones and not their nervous system. Females also change colors when they are pregnant or want to warn away males. Though chameleons are not the only organisms that can change color, they are among the fastest that can. Next, are the eyes of a chameleon. Their eyes are large and sit on the side of their heads. They are able to move separately and almost view 360 degrees of their surroundings (Foden, 2014). They are also able to move their eyes around without moving their heads. Another feature is their tongue. A chameleon’s tongue can be one and a half times longer than their body. When it is not extended, it sits coiled inside of their neck. They are able to extend their tongues to catch insects without being noticed, and the insects stick to it making it easier to catch. The fourth feature of a chameleon is their feet. Each foot has five toes. The feet in the front has two toes going outward and three toes going inward, while the back feet are the opposite. Their feet help them to grip braches to climb and stay mobile. Lastly, is a chameleon’s tail. Their tail is used for gripping while moving and to maintain their balance. When a chameleon feels threatened they can coil it, or roll it up, to make them appear larger while defensive. The inner structure of chameleons is also important in survival, ii (Neumann). They consist of a heart, oesophagus, lungs, liver, intestine, fat bodies, gal bladder, kidney, and cloaca. Females also have ovaries and oviducts for reproduction. They have a skeletal system that includes a very unique and important bone, the hyoid, iii (Terraristik). The hyoid is the bone that is connected to their  tongue. When chameleons extend their tongues you will notice that up close the bone’s outline is seen through the tongue. The hyoid is also used against predators when a chameleon feels threatened. They will push it down to extend their throat out to give the appearance that they are larger. It is clear to see that chameleons have evolved and are able to use many techniques to defend off predators. They are able to use their bodies to communicate with one another and express their feelings. Chameleons are also able to survive in normal and some extreme climates and habitats. The myth of chameleons being able to blend in with their surroundings has clearly been proven to be the completely opposite, as they change to stand out. In conclusion, there are many species of chameleons that have been around for many years, but they have evolved greatly over time. i (Komeleons) ii (Neumann) iii (Terraristik) References Bishop, G.

Reverend Grandpa in Cold Sassy Tree :: Cold Sassy Tree

Reverend Grandpa in Cold Sassy Tree  Ã‚      Cold Sassy Tree  Ã‚   In life, people look for direction.   Everyone in the world needs a helping hand.   Some people turn to one another while others turn to forces, which are of great power.   People turn to great forces such as God.   There are many people who live according to the rules of God, out of the bible or whatever book they consider holy.   So therefore, these people are directed in leading a better life.   In the brilliant novel Cold Sassy Tree, by Olive Ann Burns, Grandpa is such a person.   Whenever Grandpa faces an obstacle, he turns to God.     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Grandpa turns to God whenever he needs true help.   Grandpa is a type of person who is mild, witty, and very religious.   Grandpa uses religion to solve many of his problems.   At the beginning of the story, Miss Love was the target of gossip.   The whole entire town viewed her as an outsider and couldn’t understand why she married Grandpa, especially after his wife recently died.   After Grandpa elopes, he comes back to the house and finds a group of people mourning the sad death.   He introduces his new bride and then out of no where, Grandpa says, â€Å"Lord above, afore this gatherin’ assembled, I ask You to bless the memory of Miss Mattie Lou† (Page 99).   Everyone stood in silence as Grandpa continued the prayer.   Then all of the sudden, people also began to pray along with Grandpa.   This is amazing.   Grandpa used the power of God to divert the feelings of the crowd.   It is very sly of G randpa to do that.   Later on, Will is talking to Grandpa about his frightening encounter with the train.   Will asks Grandpa if â€Å"[he is] alive [because] of God’s will† (Page 97).   Obviously, Grandpa responds with wise words.   He tells Will that â€Å"God gave [him] a brain† (Page 97).   This shows that Grandpa believes God doesn’t do everything.   He believes God only does major things.   He isn’t there twenty four hours a day but God gives one certain abilities which help at all times.   Furthermore, Grandpa starts to give Will a sermon.   Grandpa tells him that â€Å"[One] don’t git thangs jest by astin’† (Page 98).   This shows that Grandpa is an well-educated man who understands the importance of God.   He doesn’t even waste his time asking for petty little things because he knows that God would not listen.

Social Responsibility of Business

However, in the 21st century it is a firms' responsibility to create a broader range of value along what is called the Triple Bottom Line, which consists of people, planet, and profits. Although financial profit is vital for a firm to exist, the intangible benefits that come from operating with society and the environment in mind go way beyond pure financial gain. As a manager, hiring hard-working and competent individuals to work for your firm is obviously important, but it is often not enough.Your employees are takeovers Just like you, your customers, your suppliers, and even the firm's shareholders. Taking their concerns into consideration, and allowing them to express themselves openly and honestly can make them much happier employees. Happy employees provide better quality customer service, which leads to happier customers. Happier customers lead to more business, which leads to happy investors. In other words, making your employees happy can have prosperous results.Although con ducting â€Å"green† business is expensive and may require costly investments depending on what industry a firm is in, we are obligated as a planet to move in that direction. Practices like pollution and deforestation, along with byproducts like CA emissions are very rough on the environment, and unless we engage in cleaner, more sustainable practices, we may cause irreversible damage to the planet. A quote comes to mind, although I don't remember where I heard it from: â€Å"If you think economics is more important than the environment, try counting your money while holding your breath. Yes, it's a bit extreme, but it effectively puts the importance of the environment into perspective, and reminds us that there are future generations relying on our consideration and treatment of the environment. I hope that businesses in the 21st century will take more accommodative and proactive strategies toward CARS practices than their historical counterparts. Due to the costly nature o f CARS related activities, I doubt that all organizations will truly support CARS activities, and will continue to take reactive and defensive stances regarding CARS.Being realistic, however, we can see that CARS is becoming a hot topic mongo firms around the world, which means Coos and other shareholders are likely to begin to push their company's in that direction. It may be because the shareholders are genuinely concerned with ongoing social issues and the sustainability of our environment, or it may be because the CEO simply wants to promote their company in a positive way to the public. Either way, it seems that CARS will become much more accepted and practiced as the 21st century progresses. Both the benefits of implementing CARS activities and the inevitable costs of ignoring them cannot be denied.

The s Theory Of Entrepreneurship - 910 Words

As one looks at the history of entrepreneurship, they will notice the variety of definitions and entrepreneurial elements that economists use to explain the topic. Although there are many vital parts of this concept, Israel Kirzner developed his own view that many economists take into account when creating their own definition. Basically, Kirzner’s theory of entrepreneurship held the idea of alertness as its backbone. Without the use of alertness, entrepreneurs would never discover opportunities, which allows their competitors to easily surpass them. However, if the entrepreneur is alert, then they will notice an opportunity where innovation is needed and in return they will usually profit. When others analyzed Kirzner’s theory, they criticized the amount of value that Kirzner put on alertness because they believed he lost sight of the creativity and the imagination aspect of entrepreneurship. After Kirzner developed his theory, years later an economist by the name of F rederic Sautet decided to elaborate more on Kirzner’s concept. Basically, Sautet portrayed alertness as the central piece to his and Kirzner’s view of an entrepreneur; however, he went into more depth in order to help silence Kirzner’s critics. Sautet explains, â€Å"It simply means that before one unleashes one’s own creativity, imagination, and judgment, one has to come to recognize one’s own creativity, imagination, and judgment†(95). Sautet explains that Kirzner did not disregard creativity and imaginationShow MoreRelatedResource Based View of Social Entrepreneurship: Puting the Pieces Together813 Words   |  3 Pages INTRODUCTION The emerging field of social entrepreneurship calls for a need for new integrated theories to contribute to the discipline and help grow the field.
