Hello there.
<span>The crossing over is a process where the chromatids pair and exchange sections of DNA, which lead to exchange genes (this result is call genetic recombination). So, the crossing over between nonsister chromatids during meiosis is significant in heredity because it leads to an increase of genetic variation (answer d.)</span>
Answer:
I think it's D
Explanation:
Don't take my word for it
The answer is C - Organ of Corti.
Organ of Corti is considered as body's microphone. It is present on basilar membrane which is floor of cochlear duct. Mechanoreceptors of ear are present in organ of Corti. On the internal side of organ of Corti, many hair cells are present. These hair cells are the sensory receptors for sound. When there is fluid motion in the ear due to sound waves, these hair cells generate electric signals which are then sent to brain and sound is perceived.
