Conifer cone

know forest fires took place in the U.S in states like California, Arizona, and New Mexico simply from flipping through news channels. This documentary opened my eyes to just how powerful forest fires can be and how they affect the ecosystem and environment around us. What also shocked me as the documentary came on was the opening quote, “Earth is the only planet in our solar system that burns ... and there 's one main reason why. Plants.” I didn’t really put into perspective that Earth is the only planet that can burn but never would have guessed plants are the core reason. Along with the stories that interested me in the documentary, it was shocking to hear Dr. Nate McDowell predict conifer trees will not exist in 2050 because mega-fires are killing them off. After seeing exactly what conifer trees look like, I know they are heavily populated in forest areas and for an ecologist to assume they will be extinct in 35 years is astonishing after being around for hundreds of thousands of…

This paper will look at the Haida traditional uses of trees, shrubs, flowers, ferns, and mosses found on the archipelago. Due to the cool and wet climate along with the nutrient-poor soils, conifer species such as Western hemlock, Sitka spruce, and Western red cedar dominate Haida Gwaii’s forests (Banner et al., 2014). However, the deciduous red alder tree dominated the forest at the beginning of the trail as the earlier part of the trail was new growth. This is because red alder thrives in…

In Robert Frost's Poem "Stopping By Woods on A Snowy Evening" the speaker chooses to surround himself with the dangers of nature away from the comforts of society; whereas Tennyson's "The Lady of Shalott" is in a tower locked away from the beauties of society because of her own fears. As the speaker in Frost's poem secludes himself from society he notices the dangers around him and what they could potentially cause. In Robert Frost's poem "Stopping by Woods on a Snowy Evening" he describes a man…

1. a) Define Deuteronopia. b) What causes it? c) Why is it more frequent in males than females? d) Contrast the two types of receptor cells in the retina, and describe the retina’s reaction to light. Deuteranopia is when someone is colorblind, which results from the exposure to green light, causing the person to be confused, mixing up the colors as green, red, and yellow. Color blindness is caused by the green sensitive cones. In addition, deuteranopia is caused by a genetic condition where…

nose, and tongue. Our vision comes from our sense organ, our eyes and travels to the part of the brain that processes vision, the occipital lobe. From there what we see is a perception of what we are getting from our sense organ. Our perception of color in particular is shaped by the culture that we live in and biologically through the rods and cones in our eyes (How vision works, 2015). The way that the brain sees color is biologically based, and perception…

Do We Take Color For Granted? What is color? Color is something that is so beautiful, that no words are able to describe its wondrous beauty. There are three primary colors, well for humans. There are cone cells in the human eye, and cone cells are what allow us not just us humans but all living beings to perceive color. Humans have three different cone cells, and each of them have one hundred shades of color, so we are able to see about a million colors. But can humans actually see color that…

With these two disorders you can either have partial color blindness or total color blindness in one or both eyes. Color blindness is easy to detect and can be self-diagnosed for most people. If your color blindness is not inherited then it can be caused by a number of different diseases and you should see a doctor immediately after realizing your vision is not the same to prevent any serious condition. The reason that color blindness occurs starts in the retina of the eyeball. It is the…

SCIENTIFIC CONTENT The scientific content I have displayed throughout my photography was the anatomy of the retina of the human eye. The retina of the eye is a thin layer of tissue that lines the back of the eye. The purpose of the retina is to receive light that is seen by the lens of the eye, convert the light into neural signals, and send the signals into the visual cortex of the brain for visual recognition. The retina consists of several different parts, that are all crucial to the…

about how amazing it is to be able to perceive the world around me. I understood that from the retina to the brain, perception goes from complex to extremely complex. In other words, being able to experience the real world is one of the marvelous opportunities that we have. This phenomenon starts with light getting in contact with the cornea continuing to the back of the eyes, to the retina, before light goes to the optic nerve and end up in the brain. This process appears to be simple;…

One of the cultural myths that I have fallen into would have to be the ‘colorblindness is progress’. I’ve always seen past people and their color, or where they came from. I enclosed myself in the mindset of ‘I’m not racist because I don’t look at people’s skin color or background’. After learning about color blindness, and realizing that I was apart of it, I now know that this is the wrong way to view humans. Color blindness may seem like a good idea, and the intention might be of good intent;…
