As a rule, the gill area is greater in fast-moving crabs (Portunids) than in sluggish bottom dwellers; decreases progressively from wholly aquatic, to intertidal, to land species; and is greater in young crabs than in older crabs. Often the gills are enclosed in protective chambers, and ventilation is provided by specialized appendages that create the respiratory current. As in cephalopod mollusks, oxygen utilization is relatively high—up to 70 percent of the oxygen is extracted from the water…

containing cDNA of human interferon gamma is kept under the control of 3-phosphoglycerte kinase promoter in the yeast Saccharomyces cerevisiae. The amount of of expression was greater under PGK promoter than just the IFN-γ mRNA. 25 x 10 (6) units per litre culture of active IFN-γ are synthesized in transformed…
Livestock production and climate change affect and get influenced by each other. The most important effects of climate change on the environment and livestock include rise in temperature, elevation in sea level, alteration in microbial eco-system and several others effects, known or unknown which might affect the livestock positively or negatively. There have been various predictions about the quantum of sea level rise with varying degree of confidence because many of the natural phenomena have…

plant. Normally focus more on COD and municipalities more on BOD removal. With chemical treatment, removal of COD is improved at basically all kinds of wastewater plants. The BOD value is most commonly expressed in milligrams of oxygen consumed per litre of sample during 5 days of incubation at 20 °C and is often used as a surrogate of the degree of organic pollution of water. (Clair N. Sawyer,…
Objective: The objective of this lab is to show how diffusion occurs with different types of osmosis. This is done with varying concentrations of solute. Introduction: To fully understand this experiment you should have a solid basis of background information on a few a topics. The cell membrane, for example, is the flexible barrier which surrounds the cell (see Figure 1). This organelle controls what is able to enter and exit the cell, which is known as selective permeability. The…
Should the UK move towards wind energy as its primary energy source? As fossil fuels are finite, wind energy is looked at as an alternative source of energy. Wind energy produces renewable energy through the extraction of air flow to create energy. Currently, the UK is the sixth largest producer of wind energy in the world (Global Wind Energy Outlook, 2014), however the questions remains whether the UK should continue to invest in wind power compared to other renewable sources of energy. The…
With the rapid development of the global economy, the world 's demand for oil continues to increase. When conventional oil resources cannot meet the rapid growth of oil demand, people turn their attention to unconventional oil resources, which is an important source of oil sands. By the sand, asphalt, mineral, clay and water in five parts of the oil sands is a kind of unconventional oil resources. It is distributed widely, and is rich in resources. At present, the world oil sand technology is…
