Briefly describe how a biological contaminant was able to get into groundwater wells at walkerton?
The biological contaminant, E. coli bacteria, likely entered the groundwater wells at Walkerton due to surface water runoff carrying manure from nearby farms contaminated with the bacteria. Heavy rainfall washed the E. coli from the manure into the groundwater supply, leading to widespread contamination.
How does biological evidence support the theory of evolution?
Evolution is based on the principle of natural selection, so in order to see what science has come up with as "evidence", you must understand natural selection. Briefly, natural selection is when a group of organisms detect a change in their habitat and start spontaneous changes in their anatomy or behaviour through generations. Scientists have made research on a certain insect that used to feed off of hay, this type of insect lived off of hay around the world, so it wasn't a specific case. A couple of years later, farmers have noticed that those insects have now started to feed off of apples. After scientists got involved and started studying the insects, they tracked the whole change of behaviour down to a small farm in America. This farm used to be filled with cows and the farmer then sold all his cows to a milk company, so he got rid of the insect-infested hay that was the cows' food. The farmer then started planting apple trees instead, and he had a lot of those insects in his area so after a while the insects correctly "adapted" to the fact that hay wasn't available and apples were, so that was proof for natural selection. That was proof for evolution.
Explain in briefly Berkley and Hartley's method of osmotic pressure measurement and states its uses?
Berkley and Hartley's method of osmotic pressure measurement involves using a semipermeable membrane to separate a solution from its pure solvent. The difference in height between the two liquid levels in a U-shaped tube is used to measure the osmotic pressure of the solution. This method is commonly used to determine the molecular weight of unknown substances and can also be used in medical and biological research to study cell membranes and concentrations of substances in biological fluids.
Can you briefly discuss the difference between a concentration gradient and concentration difference?
A concentration gradient refers to the gradual change in concentration of a substance over a distance, while a concentration difference simply indicates the variation in concentration between two points. In essence, a concentration gradient describes how the concentration changes across a space, whereas a concentration difference highlights the contrast in concentration between specific locations.
