Answer:
Prophase II meiosis-chromosomes-6 and 12 DNA molecules per cell.
Explanation:
Meiosis is a unique type of division that occur in cells in which the chromosome number is decreased to half with the creation of haploid cells. It can be referred to as reduction division and it mostly occurs in organisms which go through sexual reproduction.
In prophase II , the nucleoli and nuclear membrane disappear.
The chromatids reduces in length to become short and thick .
The centromeres migrates to the polar regions and set the spindle fibres in place for the second meiotic division.
Therefore, at Prophase II of meiosis
The daughter cells are haploid. Its haploid cells should possess six chromosomes and 12 DNA molecules.

Answer:
Mechanoreception
Explanation:
Mechanoreception is usually defined as the ability of an organism, such as humans and animals, to perceive and react to certain types of stimuli. This may include a sensation like sound, touch, that are produced in an environment.
This involves the conversion of sound waves (which are mechanical vibrations) into nerve impulses which are in the form of electrical signals. Initially, this process starts with the vibration of the eardrum and immediately transmits these vibrations towards the three small bones that are located in the middle portion of the ear. These are then carried by the auditory nerve into the brain. The brain finally converts this information into electrical signals. This entire process eventually leads to the creation of sound within the temporal lobe inside the brain.
