Answer:
For a contraction to occur there must first be a stimulation of the muscle in the form of an impulse (action potential) from a motor neuron (nerve that connects to muscle). Note that one motor neuron does not stimulate the entire muscle but only a number of muscle fibres within a muscle.
Explanation:
Answer:
Phenotypes
Explanation:
If a trait is simply controlled by 2 alleles, there is a maximum of three phenotypes that can be produced from the alleles. Either the individual is homozygous dominant (AA), homozygous recessive (aa), or heterozygous (Aa). This would give a maximum of 3 different phenotypes, potentially only 2 phenotypes if the trait is completely dominant
In contrast, if a trait is controlled by lots of alleles (either at the same gene or different genes) there are many more possibilities for the final phenotype, as each allele might contribute something slightly different.
They specify the order of amino acids in a protein from N-terminus to C-terminus
The patient is at increased risk for a tetanus infection. Tetanus is caused by a toxin produced by the bacteria Clostridium tetani wherein it manifests as the spastic contraction of muscles. The most common manifestation of overt tetany is lockjaw or ophisthonos.
