DNA helicase breaks the hydrogen bonds between the base pairs in the double-stranded DNA. RNA nucleotides then line up beside their corresponding nitrogenous base (A-T, C-G) along the template strand of t...

A phagocyte will engulf the pathogen by endocytosis. The vesicle containing the pathogen will fuse with the lysosome where it is degraded by hydrolytic enzymes. Short peptides of the pathogen will be disp...

For an object to stay in a steady orbit; F=mv²/r where: F is the force on the object towards the centre of the orbit, m is the mass of the object, v is the radial velocity of the object, and r ...

First multiply out the right hand side to get5x + 10 = 10x^2 + 20xThen rearrange so everything equals zero, forming a quadratic equation10x^2 + 15x - 10 = 0 To make things easier, you can simplify the equ...
