-DNA and RNA are very similar in their molecular structure. Both of them are formed by smaller units called nucleotides. A nucleotide is composed by 3 parts: a sugar group, a phosphate group and a nitroge...

To differentiate y, we must used the product rule.The product rule is d/dx [f(x)g(x)] = f'(x)g(x) + g'(x)f(x)So here, we let f(x)= x^3 and g(x)= sin(x)Then, f'(x)= 3x^2 and g'(x) = cos(x)Then substituting...

The direct translation of this sentence would be; "J'ai joué le foot dans le parc avec mes amis."Translating this sentence isn't as easy as it first appears, as there are many specific details t...
