Describe the process of Eutrophication.

Excess nitrates and phosphates are water soluble and enter rivers/lakes/waterway due to leaching.Algae in the water use the increased level of ions for growth. This is called Algal bloom.Build up of algae on...

Genetic engineering can be used to modify the genome of an organism to express desirable characteristics. Outline the steps of producing a recombinant DNA molecule.

The steps are as follows:The desired gene is isolated by 'cutting' it out using a restriction enzyme. The same restriction enzyme is then used to 'cut' a vector (plasmid or virus). These can either be left a...

Describe simple harmonic motion (SHM). Sketch a displacement-time graph for a particle undergoing SHM and the corresponding velocity-time and acceleration-time graphs. Use these graphs to describe the relationship between accleration and displacment.

Simple harmonic motion is periodic motion in which a restoring force acts in the opposite direction to that of displacement and is directly proportional to the displacement.The displacement-time graph for SH...

A spring with a spring constant k is connected to the ceiling. First a weight of mass m is connected to the spring. Deduce the new equilibrium position of the spring, find its equation of motion and hence deduce its frequency f.

Let's first find the equilibrium position of the spring. When the mass is first attached the spring will oscillate like a simple harmonic oscillator, in the real world the oscillator will eventually settle a...
