D.
If the vibrations have a low frequency, the sound is heard as a __low-pitched sound_____. If the vibrations have a high frequency, then the sound is heard as a __high-pitched sound_____.
Explanation:
High pitched sound is of higher frequency because they make the air molecules vibrate much faster than low-pitched sound. Due to their high frequency, their wavelength is shorter (Remember wavelength and frequency are inversely proportional). Vice versa is true to the low-pitched sound. They vibrate air molecules slower than high-pitched sound. Their wavelength is longer and frequency smaller.

Explanation:
In a strand of DNA, Adenine and Thymine form complementary pairs, while Guanine and Cytosine form complementary pairs. This sequence lacks Guanine and Cytosine.
Answer:
<h2>
Histone acetylation increase transcription.
</h2><h2>
Whereas DNA methylation decrease transcription
</h2>
Explanation:
Histone acetylation is a transcription-activating modification which occurs by the addition of acetyl group from acetyl coenzyme A, to one or more lysine residues at the ε-amino group by the enzyme histone acetyltransferases. Histone acetylation increase transcription.
DNA methylation is one of the mechanisms that cells use to control gene expression and DNA become unavailable for transcription . In DNA methylation, DNA become inactive( unavailable for transcription) so that transcription wouldn't occur.
