im so tired :( but dinner is still cooking so i cant sleep yet ....

well... as it passes through a random leg muscle for example... - decreases in glucose - increases in carbon dioxide - decreases in oxygen as it passes through the kidney... - decreases in glucose - increases in carbon dioxide - decreases in oxygen - decreases in urea etc etc

^ is bio your last exam ?! :O (i dont know if maths standard means general or not ....) (i was talking to Lil - Azn)

^ *macfarlane burnet :)

^ that is an example of co-dominance yes

an organism must: - be able to survive outside a host or be readily transferred - have a mechanism to be transferred from organism to organism. - be able to reproduce in large enough numbers to cause disease. - be able to enter an organism and reproduce without being destroyed by the body's...

.....any biotech studiers here ?

Aldosterone controls salt levels in the blood. It is produced by the adrenal glands above the kidneys. If blood pressure levels are low and the body needs salt, then more aldosterone is released, and it stimulates the nephrons to decrease reabsorption of potassium and increase reabsorption of...

Mangroves must regulate their salt concentration because they grow in estuaries, where rivers meet the sea, and so must survive in constantly varying salt levels. They can do this by either accumulating the salt in their leaves and then shedding them, or by excreting the salt from their leaves...

Desert mammals excrete nitrogenous wastes in the form of concentrated urea in order to minimise water loss as there is little water available. Insects excrete a dry paste of uric acid in order to retain as much water as possible, as they have a high Surface area to Volume ratio and therefore...

Two changes that can occur in DNA sequences are Inversion or Duplication. Inversion is when a DNA sequence breaks and then is reattached the wrong way around. Duplication is when there is an extra copy made of a section on the same chromosome. Both of these result in changes to the DNA sequence...

Health is defined as the physical, social, and psychological well-being of a person. However, these factors are variable for everyone. For example, a 'fit' person will say they are healthy if they have no disease, however a chronically ill person may say they are feeling healthy if the symptoms...

anyone want to post more questions ? or will we just answer them ? :P :)

Reproductive technologies such as cloning result in reduced genetic diversity in a population because the chosen individual is allowed to reproduce many times in a short period of time. In the process of cloning, cells from an organism are cultured to produce mature genetically identical...

Mended investigated 7 different characteristics in the garden pea plant. He first bred his experimental plants until pure to make sure there were no other factors present. He then cross bred alternate characteristics. eg. tall/short. All the first generation were observed to show the dominant...

marine fish: - kidney contains few small glomeruli, due to the low filtration rate. - small quantities of concentrated urine are produced. - this is because the water concentration outside the body is lower than inside, so it is already losing water to the surroundings, so needs to conserve...

Donated blood is needed for patients with burns, anaemia, severe bleeding, low blood volume, etc. Artificial blood is a good substitute for this for a few reasons: - the amount of blood needed by patients is far more than what is being donated. - there is a slight risk of disease being...

It is difficult to say that something definitely causes a disease, even if it is common to all patients. Trends in lung cancer have been seen to reflect smoking habits, as a general decline in lung cancer and death in males has come at the same time as decreased smoking by men. Lung cancer has...

definitely mod C for me, its always been my fav :)
