Answer:
Number of nucleosomes in 
bp is equal to 
Explanation:
For wounding one nucleosome, total length of DNA required is equal to 
bp
The length of linker DNA in mammals is equal to 
bp
Thus , the total length of DNA that confides between two nucleosome is equal to the sum of wounding length of DNA and the linker length
bp
Thus, in 
bp length of DNA, the total number of nucleosomes is equal to 
Thus, number of nucleosomes in bp is equal to
The sensory receptors refer to the portions of the nervous system, which sense variations in the external or internal surroundings. The sensory input can be in various forms, comprising taste, pressure, light, sound, pH of blood, or levels of hormones, which are transformed into a signal and are transmitted to the brain or spinal cord.
In the sensory centers of the brain, the barrage of information is integrated and a response is produced. The response, that is, a motor output refers to a signal conducted towards organs via motor neurons, which then transforms the signal into some kind of action, like changes in heart rate, movement, discharge of hormones, and others.
