-A mutation in a pathogen may produce a new strain. This new strain may become resistant to an antibiotic through natural selection. The new strain ma...

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...

In all organisms, allows creation of bigger molecules from smaller ones

In animals, enables muscle contraction

In some animals (mammals and birds), provides heat to maintain...
