The cell membrane separates the intracellular and extracellular environments. The lipid bilayer only allows small polar molecules (such as O2 or CO2), small hydrophobic molecules (fatty acids, steroid hor...

p² + 2pq + q² = 1.0

p + q = 1.0

1.0 - p = q 

1.0 - 0.864 = 0.136

q = 0.136

-Spatial summation occurs when multiple presynaptic neurones together release enough neurotransmitter (e.g. acetylcholine) to exceed the threshold of the postsynaptic neurone. For exam...

Sence codons are used for synthesizing mRNA and are generated as complementary strand during DNA semi-conservative replication while Antisense codons are the template used for DNA replication and can't...

The fluid mosaic model describes the composition and function of cell membranes.  Membranes are made of lipids and proteins (and a few other bits and bobs but don’t worry about that here).  The lipids ...
