Using Fick's equation for photosynthesis, explain why plants with plants that have evolved to live in very dry areas use PEP carboxylase for the initial CO2 fixation enzyme rather than RUBISCO. Your answer should include which term Fick's equation is affected by using PEP carboxylase rather than RUBISCO.

In essence, fracking, also known as hydraulic fracturing, is a stimulation technique used in the exploitation of oil and natural gas resources. By injecting a mixture of water and materials known as fracking fluid at high pressure, shales are fragmented in order to release the gas it contains.

Shale formations are fine-grained, laminated sedimentary rocks, composed of fine clay particles and formed by the accumulation of sediment and organic matter into a sea.

By using this method, new fossil fuel resources can be exploited. However, this method poses serious environmental risk. Among these, air emissions consisting primarily of escaping methane as well as those produced by the equipment itself, increase the rate of climate change. Methane is a potent greenhouse gas, 84 times more potent than carbon dioxide.

Spillage from the fractured formation as well as waste pits, can contaminate both surface and ground water thus posing a serious health risk to both the human and animal populations.
