In order to answer this question you need to use integration by parts.Using the standard integration by parts formula: ∫u dv/dx dx = uv-∫v du/dx dx.Let:u=ln(x) v=(1/2)x²du/dx=1/x dv/d...

To find x, we need to create an expression from the information given. We know the area is 15 and that the area is equal to the length multiplied by the width. This gives us:(x+3)(2x-1) = 15Then we can ex...

Enzymes would have different sequence of amino acids and therefore different primary structure. This would result in different shape of a protein ie their tertiary or, if present, quaternary structure.

3 ½ = 7/22 ⅓ = 7/3To add or subtract 2 fractions, the denominator (bottom number) must be the same. To create a common denominator we can multiply the first fraction by 3 and the second by 2.This gives us...

The small intestine has several adaptations to facilitate the absorption of nutrients: a short diffusion distance (single layer of epithelium) to maximise absorption, a good blood supply to rapidly transp...
