describe and explain the differences in their energy mix (25) The energy mix is the different uses of energy that country uses. The UK does not have a balanced energy mix‚ some sources of energy are oil‚ gas‚ nuclear‚ coal and hydroelectric power. The main sources of energy come from oil and gas this is because there are reserves in the north sea‚ however production of oil and gas peaked in the 1990s but has since fallen. Gas production and oil are the main sources of energy. Gas fell from

in pond culture. Closed aquaculture systems do not have rapid turnover of water‚ but do not have a high surface to volume ratio facilitating exchange of gases‚ nutrients‚ energy etc. with the surroundings. Water quality for aquaculturists refers to the quality of water that enables successful propagation of the desired organisms. Physico-chemical parameters of water include: 1. Alkalinity Alkalinity relates to the capacity of the water to accept protons and is a measure of the water’s buffering

have a huge impact on the communication between cells. Cell communication is a crucial process necessary for cells to carry out various functions. Drugs such as Methylenedioxymethamphetamine (MDMA)‚ known as ecstasy‚ can create barriers or confusion to cells. Cell to cell communication carry messages from signaling cells to target cells. Usually a cell will bind with a target cell through a receptor protein in the plasma membrane of the target cell

Diversity in Living Organisms (Science) |Close X | |[pic] Classification And Evolution Classification refers to the identification‚ naming‚ and grouping of organisms into a formal system based on similarities in their internal and external structure or evolutionary history. It determines the methods of organizing diversity of life on earth. Therefore‚ classification helps in understanding millions of life forms in detail. Who started the classification of organisms? Let us explore the history of

Title: Confirming the Presence of Fermentation in the Conversion of Milk to Kefir Authors: Michael Ahrens‚ Nicholas Fiore‚ Garrett Hages‚ Melissa Cullom University of Kansas‚ Biol 402‚ Fall 2014‚ 3:00pm room 6040 Abstract: In this experiment milk was fermented into Kefir‚ then a series of tests were used to confirm that fermentation actually occurred. The tests used to confirm the fermentation were a gas production test‚ pH test‚ Gram stain‚ and turbidity test. The results showed during the conversion

Cell membranes are a bilayer make up of phospholipids‚ proteins‚ and cholesterol. Its main function is to regulate what comes in and out of the cell by means of diffusion‚ transport proteins and protein channels. Trans membrane proteins transport polar solutes across hydrophobic regions of the bilayer. Diffusion occurs when solutes are transferred from a high concentration of that solute to a lower concentration of solutes. Solutes do not depend on the concentration of other solutes‚ which allows

the cell appeared smaller after being exposed to starch solution was because water molecules move out of the cell because the concentration of water inside the cell was greater than outside the cell. I believe this for a few different reasons. We were given 3 different explanations to explain why the cells appear smaller after being exposed to sugar water. These include: That the sugar molecules are not able to enter the cell‚ but the sugar molecules push on the cell membrane making the cell appear
