The sliding filament theory demonstrates how the muscles in our body contract. As a signal reaches the neuromuscular junction (motor end plate), neurotransmitters such as Acetylcholine will diffuse across th...

The product rule states that if y=uv, where u and v are both functions of x , then dy/dx = u(dv/dx) + v(du/dx) Therefore, the differential of 2x e 3x can be found by letting 2x= u and e 3x =v . u= 2x, du/dx ...

Sustainability in cities involves improving and developing cities whilst preserving the environment and resources. Sustainable cities must control the use of resources. This can be done by improving the effi...

Structure of the protein is easier to understand if we start from the beginning and gradually build up our knowledge. Firstly, proteins are made of amino acids. Each amino acid is made of a central carbon at...

First, you need to find value of one part . We can see that Wim who has a share of 5 parts gets £115. So, 5 parts is equivalent to £115. Therefore, value of each part is 115/5 = £23. Now, adding the ratios 2...
