Crude oil is composed from hydrocarbons of varying chain length. Hydrocarbons with longer chains have higher boiling points due to the increasing strength of intermolecular forces with length, therefore t...

The question can be written algebraically, as:(a) 3t + 2c = 7.80(b) 5t + 4c = 14.20To work out the individual costs, we need to make one of the sets of variables equal. We can do this by multiplying the e...

Mitosis and meiosis are both types of cell division.Cells that divide by mitosis produce 2 identical daughter cells - these cells have the same number of chromosomes. These cells are important for growth ...

Where the angles of a triangle A+B+C = 180 degrees, then if follows that (where A = 90, B = 2x + 30, C = 2x):180 = 90 + 2x + 30 + 2x180 = 120 + 4x60 = 4x15 = xTherefore, it follows that A = 90, B = 60, C ...

Interphase: DNA in chromosomes replicates to have double copies of itself for mitosis. 1. Prophase: DNA in chromosomes condenses therefore becomes mo...
