Changing the ph of a solution will change the shape of the enzyme always, but as well it changes the shape of the substrate. I would say B is the correct answer

what are the three properties of components of the universe that can be determined using electromagnetic radiation

vodomira [7]

The three properties of components of the universe are frequency,wavelength and Intensity can be determined using electromagnetic radiation.Frequency is defined as the number of cycles per second, and it's unit is Hertz (Hz).Formula is E=hÎ˝. Wavelength is the distance of one full cycle of the oscillation.The wavelength related to frequency formula is c=Î»Î˝.Amplitude is the distance from the maximum vertical displacement of the wave to the middle of the wave. Then amplitude tells about the brightness of the wave.

Refer to Fig. 6.4.1 and 6.5.2 for this and the next two questions. The mutation occurs in the DNA, but questions refer to result

aalyn [17]

Answer:

A mutation that changes the first letter to 'C' is called Frameshift mutation.

Explanation:

FRAMESHIFT MUTATION -: A frameshift mutation is a genetic mutation of a number of nucleotides caused by indels (insertions or deletions) in a DNA sequence that is not divisible by three. A frameshift mutation (also called a framing error or a reading frame shift) The addition or deletion may alter the reading frame (the grouping of codons) due to the triplet nature of gene expression by codons resulting in a completely different translation from the root. A frameshift mutation, instead of being added or removed, is not the same as a single-nucleotide polymorphism in which a nucleotide is substituted. In general, a frameshift mutation will cause the reading of the codons to code for various amino acids after the mutation. The first stop codon ("UAA", "UGA" or "UAG") encountered in the series would also change the frameshift mutation. The polypeptide that is formed will be abnormally short or abnormally long, and most likely will not be functional.
Hence, the answer is Frameshift Mutation.
