When looking out onto the beach‚ there are various sections that are visibly different from one another. These zones are due to seaweed‚ the size‚ density and more obviously colours. The most common colour seaweeds are browns‚ from the phaeophycae family. During the day‚ as tides come and go‚ the seaweed becomes saturated and then starts to dry out‚ called desiccation. This coursework will look at the adaptations of seaweed?s to reduce desiccation‚ and also the factors that cause the desiccation

Asian shore crab (H. sanguineus). Today‚ the Asian shore crab is well established and is becoming a dominant crab species in Massachusetts‚ as well as much of New England. The species has become such a threat because it can tolerate vast ranges of salinity and temperature‚ is an opportunistic omnivore with a broad diet‚ females have a high fecundity with a breeding season twice as long as native crab species‚ and there are no natural predators in the non-native range. A broad diet creates the potential

during the reaction and can keep catalyzing reactions till there are no more substrates. However enzymes are tertiary proteins structures and are very dependent on the environment in which they reside in. Many factors such as pH‚ temperature‚ and salinity can affect the shape of the active site on the enzyme and decrease the rate of the reaction. Many tertiary proteins such as enzymes depend on various weak ionic bond‚ hydrogen bonds‚ disulfide bridges‚ and hydrophobic interactions(van der

The need for growing more food‚ on a sustainable basis‚ to support the ever-increasing population demands a systematic appraisal of our natural resources including climate‚ soils‚ flora‚ and fauna. Since agriculture is highly location-specific‚ grouping the available land area in the country into different agro-ecological regions based on certain identifiable characteristics becomes all the more important. This may help the country to engage in more rational planning and optimizing resource use for
