Answer:
In this case, the option D "Try repositioning the hearing aid or remove it and turn down the volume" is correct
Explanation:
Hearing Aid:
It is such a device that is used by the people who have some hearing problem.
It is a simple electronic device that has a Microphone that receive the sound from other person which is send to the Amplifier that amplifies the sound and send to the speaker so that the person with the hearing aid can listen the sound easily.

- We can't turn up the volume as doctor can still listen the whistling sound but the 70-year old is not listening his sound so there is noise is in hearing aid.
- We can't use pen and pencil as it will difficult to write for a 70 year old person and will make conversation difficult.
- We can change the position as mentioned in option D or remove the hearing aid turn the volume down so that the old man can listen clearly.
SS and ss. Since 100% of the offspring are spotted, then it would need to be SS so that it dominates over all. :)
The early change that the system makes in an effort to cope with an obstruction is that the stretch receptors in the bladder wall become hypersensitive. Urinary tract obstruction is a blockage that inhibits the flow of urine through the urinary tract, including the kidneys, ureters, bladder, and urethra. The blockage mat be partial or complete. In response to the obstruction the urinary system is capable of undergoing adaptive changes or responses to compensate for the obstruction.
This means that each dominant allele "adds" to the expression of the next dominant allele. Usually, traits are polygenic when there is wide variation in the trait. For example, humans can be many different sizes. Height is a polygenic trait, controlled by at least three genes with six alleles.
