Frequency theory of hearing
According to the frequency theory of hearing the auditory nerve's impulse corresponds to the frequency of a tone. This allows the recognition of pitch. Sounds are detected in the ear as acoustic signal in the external and middler ear. It is later on transformed in an electrical impulse that a nerve can detect in the cochlea. The theory assumes that a nerve can fire at rates of 20 to 20000 times per second. This is the assumption that the frequency of human hearing range is at 20 to 20000.

Answer: Option C) Animal
The cell wall is tough, flexible and fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides cells with structural support and protection. All BUT ONE type of organism has cells with cell walls. That is an animal
Explanation:
One distinguishing feature of animal cells compared to other living cells is the absence of cell wall.
However, the animal cell possess a cell membrane, with which it regulates substances entering or leaving the cell, and also provide protection and mechanical support for the cell against foreign invaders such as pathogens.
The probability is Ss×ss = Ss, Ss, ss, ss = 50% heterozygous genotype, 50% homozygous recessive genotype = 50% yellow phenotype, 50% phenotype
Answer:
The statement is true.
Explanation:
The DNA structure had been studied for years, and there were even some theories, like the three-stranded DNA structure. Nevertheless, until Watson and Crick started to develop the actual structure of the DNA, with the help of Rosalind Franklin's pictures, there wasn't a strong theory that could explain some of the DNA properties.
