Uv Radiation On Organisms Essay

850 words - 3 pages

This project is significant because it could help bring about a better understanding of, how UV wave lengths affect the people and the hole in the ozone layer. By determining the effects of UV on Artemia Salina we come closer to alleviating the effects of UV radiation on organisms. In the future this could lead to better UV protection technology.

IV: UV exposure in seconds
DV: Mortality Rate
DV2: Growth Rate it mm/day

H1=the UV radiation will kill more Shrimp the longer they are exposed to it.

H2=the Artemia are more likely to form defects and some form of stunted growth.
N1= The UV will have no effect and there will be no deformities or conditions of any kind on the Artemia

Artemia are small crustaceans that live in saline, in-land shores including species like crayfish and brine shrimp. These invertebrates are small, and are generally hard to see in the water, have hard exoskeletons, and little legs that are really hard to see. Males give birth to young through laying cysts, while females produce offspring via live birth, being around since the Triassic period, Pre-historic fish have been sometimes eating Artemia and other times getting picked off by hovering birds.
Artemia Salina or Sea Monkeys only go into near shore waters because most salt is far from shore and Artemia can only survive in certain salinity levels making it a little harder to culture in salt tanks. But when saline levels are just right they give peak results in experiments. They have almost no defenses but multiply quickly and are fast swimmers.
Artemia also are extremely common in marine shops being used for human or fish food and also for a variety of science projects and has a hefty sale rate, even for how sometimes expensive they are.

Methods

Safety Considerations
Hazards:

1. UV radiation: UV is dangerous to skin and eyes, can cause blindness and even cancer if precautions not used.

2. Electricity near water = The electricity could electrify the water through contact, electrocuting anyone who touches it.

Precautions:

1. UV radiation – Work under adult supervision, UV protective goggles and UV safety procedures.

2. Electricity near water=keep electrical units, as far away as possible, and avoid contact at all costs.

Because plants and certain bacteria survive off the sun one would think that more UV radiation would be beneficial to these plants and organisms but on the contrary a delicate balance must be obtained in order for the plants and organisms to work efficiently and not be harmed. Too much UV radiation may damage the DNA

Yet, not many people have written books on this subject My experiment is about how outside sources such as the UV-B rays other radiation influences the growth of plants. I have conducted an experiment where I use four different types of radiation (cosmic, UV, alpha, and beta). My findings concluded that the cosmic radiation was positive

Most of the solar radiation energy transmitted to earth is composed of infrared (~37%), visible (~43%), and UV (~7%) wavelengths (Nicholson et al., 2005). Based on a “photobiological” definition of UV (the Global Solar UV Index), it is divided into three categories: UVC (200–280 nm), UVB (280–315 nm), and UVA (315–400 nm) (WHO, 2002). On Earth, the most of the solar UV radiation is attenuated by the atmospheric

The acute effects of UV-A and UV-B exposure are both short-lived and reversible. These effects include mainly sunburn (or

Uv Rays

765 words - 3 pages The Effects of UV Rays Ultraviolet radiation (UV) is an electromagnetic spectrum between x-rays and visible light. The sun radiates energy in a wide range of wave lengths. The shorter the wavelength is the more radiation and potential for harm can come from it. The spectrum is divided into three categories UVA (315-400 nm), UVB (280-315 nm), and UVC (100-280 nm). The sun we all know is the natural source of radiation, and then we

Depleting Ozone and Its Effect on Society

1279 words - 5 pages environmentalists and researchers alike focus on the increasingly dangerous affect that ultraviolet radiation has on present day society. In order to understand how the ozone affects us we must first understand what the ozone is. What is the ozone? The ozone’s essential duty is to protect society from harmful ultraviolet rays by acting as a filter. The ozone is a layer in the middle of the stratosphere that protects the earth from the harmful ultraviolet

Nevertheless, this article dodges the question of why mammals don’t reproduce through a facultative sexual cycle.[4][5][6] One recent theory on the origin of sex is that UV radiation stirred evolution in such a way as to make sex advantageous. UV radiation is a mutagen, and exposure thereto causes
