The liver of a dog has been found to have higher than normal cell death because the dna is damaged. What part of the cell failed
katovenus [111]

Answer:

This is a slightly vague question because there are many reasons why DNA can be damaged and determining which organelle was at fault is generally a case by case matter. but the only part of a cell that you could considered to be tasked with protecting genetic material is the nuclear envelope which is simply a phospholipid bilayer surrounding the nucleus and/or the nucleolus so I would say the answer is the nuclear membrane and/or nuclear envelope.

In a musical instrument, sound waves build up by constructive interference until they are loud enough to hear. This concept is k
zalisa [80]

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.

What is the sequence of events in the transmission of an impulse through the heart muscle?
zimovet [89]
<span>The sequence is as follows:
c, d, a, b, f, g, e

The impulse starts at the SA node that has its own contraction rhythm (but can be faster or slower depending on other impulses or hormones). That impulse travels then through the atria and is slowed down by the atrioventricular septum except for a region in the right atrium called AV node where the impulse has continuity. The impulse travels then to the ventricles through the AV bundle. The impulse continues through bundle branches to other fibers: Purkinje fibers. These Purkinje fibers cause then a contraction that goes from the apex of the heart and rapidly through the ventricles.</span>
