Factors Limiting Photosynthesis The rate of photosynthesis increases with increasing light intensity. But too much light intensity can slow down the rate of photosynthesis because the light damages chloroplasts in the leaf. The higher the temperature the greater the rate of photosynthesis as photosynthesis is a chemical reaction and chemical reactions increase with temperature. But at temperatures above 40 C the rate slows down because the enzymes involved are destroyed

To numerous people‚ pigs are a nuisance. They are usually viewed as dirty animals with no purpose other than for food. However‚ pigs contribute greatly to the environment. They are able to digest certain substances easier than humans and use resources to make life easier for us. On the other hand‚ phosphorus‚ one of the many essential nutrients for swine‚ has negatively impacted the environment due to swine excretions. Elevating this problem has led to the genetic improvement of swine. Phosphorus

the environment must survive the cold air and the nature of waves. 9 different species and their populations were simulated. The simulated environmental community contains 4 species of mobile consumers‚ 3 species of filter feeders‚ and 3 species of algae. The species were Black Pine‚ Coral Weed‚ Acorn Barnacle‚ Nori Seaweed‚ Mussel‚ Goose Neck Barnacle‚ Whelk‚ Chiton‚ Starfish and Green Crab. Green Crab feed on prey such as Chiton‚ Mussel‚ Whelk‚ Acorn Barnacle‚ Starfish‚ and

Bill Kozel Ms. Livingston English Comp 2 18 September 2012 Alternative Fuels in America On a national average the world uses 87.8 million barrels of crude oil on a daily basis. In 2000 it was estimated that the US alone consumed nearly 20 million barrels of oil a day‚ which is about 5% more than similar nations (Friedman 195). Oil consumption is only going to increase until it peaks‚ then it will steadily decrease as oil supply goes down. It is predicted that oil consumption will peak by the year

Antonie van Leeuwenhoek’s discovery of microorganisms in 1675‚ using a microscope of his own design. Microorganisms are very diverse and include all the bacteria and archaea and almost all the protozoa. They also include some members of the fungi‚ algae‚ and animals such as rotifers. Many macro animals and plants have juvenile stages which are also microorganisms. Some microbiologists also classify viruses as microorganisms‚ but others consider these as nonliving.[2][3] Most microorganisms are microscopic

tested dyes‚ Chara extract precipitate more than 90% of dyes after 5th days of incubation. Maximum precipitation of FD2 dye occurred was about 98.28% and lowest percentage was observed in FD5 about 90.36%. Even though‚ the similar extract of Chara algae were used for beads preparation (Immobilization)‚ different results were observed wherein maximum amount of FD3 dye (93.67%) was precipitated and minimum was FD5 (61.04%). The differences may be attributed to the specific enzymes present in extracts

In this talk Plant fuels that could power a jet‚ NASA engineer Bilal Bomani presents his work in turning the field of aviation into an environmentally friendly service. At NASA’s GreenLab Research Facility‚ he uses algae and halophytes to create a self-sustaining‚ renewable energy ecosystem that doesn’t consume arable land or fresh water. Bomani’s work has a set of guidelines which it must follow. In order to be truly Green‚ Bomani’s fuel must be Sustainable‚ Alternative and Renewable. Meaning that

The causes of pollution Pollution is the release of harmful environmental contaminants. The main air pollutants are carbon monoxide‚ lead oxides‚ sulfur dioxide and nitrogen oxides. The principle causes of pollution are exhaust pipes from motor vehicles‚ smoke released by factories and moreover‚ industrial plants burn coal and oil‚ which contain sulfur. New inventions and processes have been continuously developed to improve our way of life; such developments are called technological

question what kinds of factors are affecting the creek water to kill off the duckweed. Duckweed also is known to stop the growth of algae‚ but in our experiment we ended up having algae grow in some of the wells filled with creek water. We feel as though the creek water might have had some chemicals in it through runoff that would be harmful to duckweed but beneficial to the algae growing in those wells. Over the course of six weeks‚ we saw a lot of changes in the Thalli. We noticed that the growth of thalli
