Answer:
The right answer to the concept whereby sound waves undergo constructive intereference to producing a louder sound in musical instrument would be superimposition.
Explanation:
When sound waves are produced, especially from a musical instrument, numerous beats are produced, which have different frequencies. The sound waves mix with each other in any of Destructive or constructive interference. When the waves are moving in the opposite direction with the same amplitude, they tend to cancel out each other to produce a quieter sound wave. The constructive interference of sound waves results in a wave with an accumulated amplitude of individual waves, thereby producing a louder sound wave. When sound waves are in combination into a higher amplitude is called superimposition.
Answer:
c) probably a mixture of DNA and RNA.
Explanation:
DNA and RNA are the two types of nucleic acids present in cells. DNA or deoxyribose nucleic acid is composed of four type of bases ( adenine, thymine, guanine and cytosine ), deoxyribose sugar and phosphate group. RNA or ribose nucleic acid is composed of four types of bases ( adenine, uracil, guanine and cytosine), ribose sugar and phosphate group.
Here, the sample had adenine which could be either from DNA or RNA. Thymine is from DNA. Ribose sugar is from RNA and uracil is from RNA. Hence, the sample has a mixture of DNA and RNA.
This is known as the pericardium
This is true, for it is called redshift
