Biological pigment

The first subcategory is wear and tear theory, which theorizes that biological aging is like an aging car. As time passes and parts are used frequently, those parts become worn down and quit working. Applied to the body, that means cells eventually die off from use, and aging occurs as a result. Rate of living theory is the…

ago. In Africa it is very hot and there is a lot of UVB radiation. So when humans moved away from these high UVB areas we needed to adapt to be able to still synthesize vitamin D adequately. The authors guess that we did just that by slowly losing pigment over time. Michael Holick, from Boston University, did a study that spanned twenty years. His research concluded that not all sunlight contains enough UVB rays for our bodies to synthesize vitamin D. In Boston, for example, your body will not…

factory does, where all machines have its own specialised particular job to do. All living has a system that is indubitably crucial in order to function body properly and sustain a healthy body. It is ineffable in a way that our body performs numerous biological process at the same time such as respiration, digestion, metabolism and invading infectious microorganism. The assemblage of these different body systems facilitates the process to work together and create a state of balance in our body.…

Introduction When analyzing biological processes and development, Drosophila melanogaster is an ideal organism to utilize. Compared to other organisms, the functions of D. melanogaster are easier to manipulate due to its quick sedation time from carbon dioxide. These flies can be sedated in less than ten seconds with a carbon dioxide flow rate of 5L/min. D. melanogaster also produces offspring in a short amount of time (roughly 10 days at 25 degrees Celsius), which makes it a desirable species…

much in advance what to expect out of cosmetic skin procedures. Before we take a look at the ways we effectively treat skin pigmentation, let us first comprehend its causes. Your skin is comprised of cells known as melanocytes. These cells produce a pigment known as melanin, which gives skin its natural colour. The total number of melanocytes that are present in your skin eventually determines the colour of your skin. Besides giving skin its colour, melanin offers protection to the skin from the…

enclosure wall and the well. The temple precinct had an area of 74×51 meters; the temple itself is much smaller - 13×16m. Its entrance faces east. The outer walls don't have much decoration but on the inside the reliefs are well preserved and some have pigments. According to inscriptions on the propylon, construction of the Isis temple started around the beginning of 1st century CE [1]. According to one theory the temple's construction started…

scientific understanding is as extravagant as it has ever been, there are many artists who continue to use their knowledge to break new ground with their work. One such artist is Klari Reis. Klari Reis is an artist based in San Francisco who uses biological research techniques as both conceptual and inspiration…

Identification of bacteria can be a difficult process due to the fact that individual bacterial cells can possess similar structural morphology to other types of bacteria. As we have demonstrated in previous lab experiments there are key biological and chemical processes that are characteristic to different types of bacteria. Using various biochemical tests we can evaluate and detect these different processes to aid in our identification of unknown bacterial samples. The implications of these…

Many people to this day still believe that race is biological, but race is actually and has been socially constructed. Race is not something you are born with but it’s something that’s done to your body, done through a series of social forces; different forms of knowledge also do it. The argument that race is socially constructed and not biological is both important and significant. Gathering support from either philosophers and sociologists to naturalists, their work shapes around race and its…
