<span>The parotid salivary glands are </span><span>located ventral to the ear and produce nearly half of the total volume of saliva produced. They are the major salivary glands in animals and humans.</span>The parotid gland has four surfaces — superficial or lateral, superior, anteromedial, and posteromedial and receives both sensory and autonomic innervation.
Answer:
approximately 150 amino acids
Explanation:
Proteins are produced from genes via a process called gene expression. In this process, the gene-containing DNA is first transcribed into mRNA molecule, which is subsequently translated into an amino acid sequence that makes up the protein molecule.
However, during the translation process, the mRNA molecule is read in a group of three nucleotides called CODON i.e. a codon is made up of three nucleotide/nitrogenous bases. Each codon codes for a particular amino acid.
Since one codon of a mRNA that is three (3) nucleotides long codes for one amino acid, hence, strand of mRNA that is 450 nitrogenous bases long will produce a protein containing approximately (450/3) = 150 amino acids.
The statement which best describes artificial selection as compared to natural selection is: C. In artificial selection, the passing on of traits is determined by human choice.
<h3>What is artificial selection?</h3>
An artificial selection can be defined as a process that typically involves human beings breeding living organisms such as <u>animals</u> and <u>plants</u> to favor a desirable characteristic or trait.
This ultimately implies that, the passing on of traits or characteristics is generally determined by human choice in artificial selection rather than in natural selection.
