Answer:
Digital and analog signals are transmitted through electromagnetic waves. Changes in frequency and amplitude create the music you listen to or images that you see on a screen. Analog signals are composed of continuous waves that can have any values for frequency and amplitude.
During hypoglycemic conditions where the body is starved of glucose,body fats will be metabolized to produce ketone bodies as an alternate fuel for brain cells
Answer:
Explanation:
DNA mutations could be silent and have no effect, others affect protein synthesis. Mutation is a change in a DNA sequence brought about either by a mistake made when the DNA is copied or through chemical damage.
A point mutation is a single-letter swap – an exchange of two bases, adenine to cytosine, for example, at a single location in the DNA molecule. Since the sequence of letters in a gene determines the sequence of amino acids in the protein it encodes, a point mutation can change the amino acid sequence of the resulting protein. Sometimes a change in the protein's amino acid sequence can have dramatic results. For example, sickle cell disease occurs when a single-point mutation in the gene that encodes the hemoglobin molecule results in deformed red blood cells.
