Dissecting the cow’s eye helped us to see all the different parts of the cow eye and see how they work and where they are in the eye. The cows eye was very helpful in identifying what our eyes look like and the how they work. I now feel confident in identifying and labelling key parts of the eye. When we got the eye it was big, fatty and gross. The fat and muscle around the eye was very soft and mushy but difficult to cut. The inside of the cows eye there was a black liquid. Ultimately, the cows eye experiment was very helpful and fun to do.

In 1802, philosopher William Paley called the eye a miracle of "design". Your eyes are responsible for 80 percent of all of the information that your brain receives. (Schleifer, 2014) But how did our eyes form? How are we able to see what we see? What allows us to see the colors we see? The eye is made up of many different complex parts that all work together to create images our brain can understand. The eye is made up of the front parts, or parts we can see, the interior parts, or parts we can’t see, the nerves which carry signals to our brain, and glands that protect our eyes. The eyes we have today have evolved over a long period of time and undergone many different changes, according to Charles Darwin, Richard Dawkins, and many other evolutionists. When all of the different parts of our eyes work together we are able to see a clear image that is produced from our brain.
Society, especially western, tends to conceptualize beauty through the use of publicity and cinema. We are under constant bombardment from consumer related magazine ads, billboards, television commercials, and movies about what “beautiful” people look like and how we should imitate them. This standard is overwhelmingly portrayed as a white beauty standard. Starting from a very young age this standard of beauty is created in our minds. We want to look like these actors and models; we want to be thin, fit, youthful looking, a symmetrical face and even have a particular race. We accept this beauty standard; we notice our various faults among ourselves and self-critique. We try to emulate the models as best we can; we forget that these standards are not reality. Publicity models and the most popular actors do not represent the majority of us and it is a foolish and unattainable dream to attempt to change ourselves to their beauty. The pressure society puts on us can cause low self-esteem and diseases such as anorexia. But we must look at the antithesis of society’s conception of this white standard, our minorities. Portraying this beauty standard to the polar opposites is more than racist. It is destructive to the minority community in that it creates resentment, low self-esteem, and a perverse hierarchy where minorities judge themselves and others on their proximity to the white beauty standard. In The Bluest Eye, Morrison critiques the white beauty standard that causes the black minority to feel a destructive self-hatred towards themselves and their fellow blacks because their self-perception is an unrealistic and unattainable beauty seen in publicity and films. This research paper’s aim is to present the influence of ...
An inspection of the modern animal phyla will reveal that eyes are just as diverse as they are complex. Some organisms like the rag worm have pigmented cup eyes while other like he box jellyfish have two lens eyes and two pairs of pigment pit eyes. To account for the diversity in eye structure, we must first examine the eye ‘prototype’, the original structure that was acted upon by evolution. The simplest organ that can be considered an eye is composed of a single photoreceptor cell and a single pigment cell, without any lens or other refractive body (Arendt, 2003). Such organs are know as eyespots, and...
Beauty is something that a lot of people in life strive for , because everyone has fitted in their mind what exactly beauty is. People know that it can help you out in life. But what most people don’t know is that, beauty is in the eye of the beholder. Meaning that beauty should not be characterized by what people are told it is, beauty is different for everyone, what is beautiful for you may be ugly to someone else. The characters in Toni Morrison’s The Bluest Eye are confronted with the ideal of beauty and strive for it whether they know it or not. The two characters that I think were followed the ideal of beauty in Toni Morrison’s story are Pauline and Pecola.
Based on experimental evidence from the Astyanax mexicanus investigation, it can be argued that eye regeneration in the dark cave environment is due to adaptive evolution. Experiments that have been carried out on Astyanax cavefish do not seem to favor the neutral mutation theory. The results from these experiments have shown that several eye genes are pleiotropic and regulatory since they have many functions in development in addition to their eye forming roles. This means that the genes do not experience the neutral decay process. Even critical eye structural genes such as retinal opsin, which functions at the base of gene cascades, are still expressed during the eye development of cavefish. This is why the adaptation hypothesis based on pleiotropy is the most credible explanation behind the loss of eyes in cave-adapted animals.
Our lives sometimes depend on our eyes. Think of covering your eyes and walking across a busy street. By investigating red eye and how it applies to our lives today, we can use it to our fullest advantage. For example, eye doctors shine bright lights into our eyes to get a look inside without harming us. This type of research can lead to major improvements on laser surgery and safer eye habits.

According to animal homeopath, Beth Murray, CCH, RSHom (NA), “symphytum is a really important remedy in eye injuries,” especially injuries from a blunt blow to the eye, an orbital fracture or a corneal abrasion. Symphytum can be very useful when an animal is suffering from eye inflammation.
...nation with effective results. Using mathematical combinations, unnecessary tests would not need to be performed on animals (Animal Testing: Toxic & Tragic). Using corneas from eye banks is a substitute that would relieve animals from Eye Irritancy Tests. Eye banks carry corneas from the deceased, whether it be human or animal. Using these corneas would be a faster and less stressful way for scientists to get better results and not have to worry about the pain of animals.
Microscope are useful in viewing the letter “e” and the cheek cells. It shows a close visual image, which help to observe the two objects. Following the methods is important, because it provides the necessary materials and the steps of the procedure. It’s extremely important to wear a apron , goggles, and gloves. Also, be cautious in using the materials. The purpose is to observe and how to use the microscope under the specimen. For the results each figure image shows the differences between the low-power and the high-power objectives. In those figure, it will explain the view of the image of a cheek cells and a close image of how does the letter “e” looks like.
