to determine the intensity and therefore the effect of the circumstances. This supported the hypothesis that the more acidic or basic the environmental condition around the beet cell, the more permeable the, membrane indicated by color intensity. Pigment leakage in the solution was analyzed by using a spectrophotometer. INTRODUCTION Plant cells have selectively permeable membrane that allows selective substances to penetrate into the cell. Cell membranes are consisting of lipid layer that are made

equator. Based on this information, the darkest pigmentation of skin is along the equator. The lightest Pigmentation of skin is near the poles. The more darkly pigmented skin will be near the equator because there is more UV light there, and the pigment

Statue of Hatshepsut Seated The seated statue of Hatshepsut is dated around ca. 1473-1458 B.C. around the 18th dynasty in Deir el-Bahri, Upper Egypt. This statue is made entirely out of indurated limestone and has a height of 195 cm, width of 49 cm, and diameter of 114 cm. Many statues like this were found in her mortuary temple that has been ransacked and destroyed by bandits and pharaohs. I consider this statue to be in very bad condition because of its age and the history behind it. From first

cannot even pay their mortgage. The expressionism movement was the beginning of the modern contemporary time in comparison to the realism movement are apples and oranges in the 1500s the artist hunt the organic objects they used to put in their pigment. These two different paintings are coming from two distinctly different periods are great examples of how art can have the comparison of apples and

(for example carotene and chlorophyll.) Chlorophyll- a green pigment, present in all green plants responsible for the absorption of light to provide energy for photosynthesis. 8.3 Key Concepts The process of photosynthesis needs light in its reactions as well as the Calvin cycle The light-dependent reactions produce

The material used for this sculpture says a lot about the time in which it was made. The early dynastic period you see a lot of sculptures being carved from limestone and light sandstone. The Pre- dynastic and early dynastic periods also carved their statues from wood and ivory. This is still true for sculptures of the later time period but is most common among the lower level elite class and the slavery class. This is not often seen carried out in the creation of royal sculptures as they upgraded

Tattoos have a history that extends far back into the furthest reaches of time. For millennia tattoos have been used to help differentiate members of tribes and regions and even of religions. But the concept of tattooing did not catch on in the Western world until 18th century explorers discovered "tatau" in Polynesia; a technique that became popular among European sailors and then spread to the general populace of Western societies. Tattoos are made by inserting indelible ink into the skin's dermis

meaning storing materials for energy production. Chloroplasts main job is for making amino acids and lipids needed for production. Algae is a good example of where you can find chloroplast. When looking at chloroplast the appearance would be a green pigment known as chlorophyll. Chlorophyll absorbs light energy for production. In plant chloroplast which are commonly found in plant leaves have different structures each of them being important. The membrane envelope contains lipids for protection, and

“The best time to plant a tree was 20 years ago, the second best time is now.” This anonymous quote is a direct reference to the issue of pollution, and the ramifications and effects it has on plants and the cycle of photosynthesis. Pollution not only directly effect plants and the cycle of photosynthesis, but pollution can also indirectly harm other elements that contribute to the life of a plant and the cycles it performs. Photosynthesis is the cycle in which light energy converts carbon dioxide
